Ubuntu 22.04 and GNOME smartcard https://askubuntu.com/questions/1567786/ubuntu-22-04-and-gnome-smartcard

I've been tasked with setting up Smartcard authentication on Ubuntu (and other flavors), but I need some help specifically with Gnome login screen on Ubuntu 22.04/24.04.

The system in question has the smartcard and krb authentication working, but for whatever reason I can't get the GNOME (GDM login) screen to start reading my USB card reader. It's a supported reader and using pkcs tools I can read the card and slot with no problem. I just can't get GNOME to attempt to read the card. The reader never flashes at all. I've followed various tutorials online to no avail.

Which is the true memory usage report on Ubuntu Server? Running 26.04 in VM https://askubuntu.com/questions/1567785/which-is-the-true-memory-usage-report-on-ubuntu-server-running-26-04-in-vm

I have installed the server on VirtualBox and allocated 2 vCPUs and 4096MB base memory.

So if I run free -h the output tells me 3.3Gi total, 474Mi used, and 2.7Gi free. Also 360Mi buff/cache and 2.8Gi available.

The same thing can be confirmed by using top. However the story changes when I use htop instead:

Memory is shown at 252M used out of 3.3G, much lower than the previous reports.
Why is this? I haven't changed any of VirtualBox's advanced settings & only used the unattended install with automatic download of Guest Additions, as well as the CPU & RAM allocations aforementioned.

Thunderbird version 140.12.0esr (64 bits) snap is messing with folders https://askubuntu.com/questions/1567781/thunderbird-version-140-12-0esr-64-bits-snap-is-messing-with-folders

Since a couple of versions, my email folders are not sorted alphabetically anymore. A search told me that I should have a command to automatically sort them out, but there is not such option on my version. I thought I could sort the folders manually and place them properly sorted. Alas, it is not working. I am unable to move one folder relative to another. (that could be a personal problem, though...). Could you please tell me how to sort them properly ? Many thanks in advance for your help. P.S. : I thought they are sorted by creation time but, no, they are not...

Browser recommendation for GPU-accelerated 3D WebGL cosmology simulations on Linux https://askubuntu.com/questions/1567776/browser-recommendation-for-gpu-accelerated-3d-webgl-cosmology-simulations-on-lin

I am a cosmology PhD student using a low-end Ubuntu laptop. My research requires frequently rendering complex 3D simulations in the browser (e.g., Gaia DR1 WebGL visualizers).

I am seeking a reliable browser recommendation based on the following technical constraints:

  • GPU Rendering Accuracy: Firefox defaults to slow CPU rendering on my setup and fails to render critical elements (e.g., orbital lines upon zooming), which appear correctly in Chromium. I need guaranteed, accurate WebGL/GPU acceleration to avoid misinterpreting browser rendering bugs as simulation errors in my thesis.

  • No Aggressive Ad-Blocking Interference: I currently use Brave, but I am concerned its aggressive "Shields" and ad-blocking scripts might silently break or alter specific simulation outputs without my knowledge.

  • Privacy & Resource Efficiency: Standard Google Chrome is not viable due to heavy telemetry and invasive ad layouts that clutter my screen and consume limited system resources.

Given the need for strict rendering fidelity for scientific data without heavy telemetry or overly aggressive script blocking, which browser would you recommend?

Thanks for your help!

Gimp crashes randomly https://askubuntu.com/questions/1567771/gimp-crashes-randomly

These Gimp random crashes make me mad. I lost my half an hour work. Why does it crash randomly? I am using 3.0.6 version. Don't know if it is flatpak or not. I have installed few plugins but crashes happen when I am not using them. These crashes actually happen when I open about 15-20 images totaling around 100-150 mbs. My laptop has 16 gb ram and AMD Ryzen 5 PRO 3500U. It isn't overheating. Does Gimp have a known bug with working on multiple images?

grub hangs up on availability of block devices https://askubuntu.com/questions/1567770/grub-hangs-up-on-availability-of-block-devices

Tried to recover boot for Ubuntu and this us what I get:
Ubuntu Wont Recover

What do I do now?

wpa2 enterprise with no certificate at (k)ubuntu26.04 - cannot connect https://askubuntu.com/questions/1567738/wpa2-enterprise-with-no-certificate-at-kubuntu26-04-cannot-connect

I just installed kubuntu 26.04; but then I just cannot connect to my University WPA2 enterprise wifi (like I could with 25.20, 24.04 and 22.04), signal eduroam.

This signal is configured with wpa2 enterprise, mschapv2 and peap, but no CA certificate.

At NetworkManager I (no longer? I cannot recall in previous kubuntu versions...) do not have a square to tick "No CA certificate" (initially I thought leaving it blank would mean "No certificate").

The command nm-connection-editor does show a window where I have such square - I save the configuration for eduroam, but I cannot devise where it is saved.

In fact, I can see a file netplan-NM-44fa4c25-2dc7-4a52-b83e-adcd7dd39185-eduroam.nmconnection at /run/NetworkManager/system-connections, but this file does not contain a line , e.g.,

system-ca-cert=false

(or whatever line I should provide to say there is no CA certificate). Also, this file is created at run time.

Yet, at /etc/NetworkManager/system-connections I produced a file netplan-NM-44fa4c25-2dc7-4a52-b83e-adcd7dd39185-eduroam.nmconnection with such line - but I could not devise how to convince the system to use this configuration file when I call for a connection to eduroam.

Currently I see some alternatives, that I do not know exactly how to put in action: i) the NetworkManager to be instructed to not use a certificate, even if it is does not present this option at its configuration window ii) the gui issued by the nm-connection-editor command to record a configuration file that does become used iii) to connect by the nmcli command, but to use a specific configuration file

I googled around , but I must miss some detail here. Thank you,

J.

As indicated, I add to the original question my new comments:

Thanks heynnema and Andrei Borzenkov for inputs.

a) I tried netplan apply and retested, no difference (so I learn there is a /etc/netplan/ directory with some .yaml configuration files); b) I thought my problem might be the CA certificate - well I might not be sure of this. I try to connect to eduroam and it keeps asking for my password, again and again. I do get this eduroam connection through windows 10 (dual boot machine). c) If I understand, this issue of CA certificate might not be the culprit. So I report what I observe at trying to log and I also write below the log "with journactl" with the "relevant lines" (sorry for the length):

"

(acessoLivre - undesirable - is the signal it gets automatically if no success in with eduroam).

I hope this brings in more details. Please, let me know if you need more information. I also try to learn from the points you raise.

Thanx.

J.

Following up: Thanks to enzyklopädie instructions below , I can connect to eduroam !

I try to learn and do better next time - I see a log from journalctl in my original question would already help, as pointed by others. I cannot devise how you enzyklopädie got the solution and the command you issued to see the alert you wrote - I think I would take ages to reach out the reason. So, help me educate myself, pls.

By the way, the command:

"

nmcli connection modify eduroam 802-1x.openssl-ciphers "DEFAULT:@SECLEVEL=0"

"

introduces the lines:

"

#Netplan: passthrough setting
openssl-ciphers=DEFAULT:@SECLEVEL=0

"

into

/run/NetworkManager/system-connections/netplan-NM-44fa4c25-2dc7-4a52-b83e-adcd7dd39185-eduroam.nmconnection

but this file is overwritten every time I come to reconnect. So, there remains the question - how to make this instruction/configuration permanent (I come and go between eduroam and other signals)?

I went further to check my thunderbird capabilities under eduroam and I cannot tell how much necessary is to set (but I did) at its configuration:

"

security.tls.version.min 1

"

and for some reason to be able to use the smtp server I use as "Connection Security: " STARTLS rather than SSL/TLS (and the corresponding correct port, of course).

OK, there remains the question "how to make a instruction/configuration permanent" for a given SSI signal?

J.

Good morning.

New additions based on the last comment by heynnema.

My understanding then is that the configuration about the SSL version to be used when I use eduroam is stored in a file called, in my case, /etc/netplan/90-NM-44fa4c25-2dc7-4a52-b83e-adcd7dd39185.yaml (id est, a yaml format file). I check it now and it has the lines (I do not describe here the complete hierarchy)

"

      802-1x.openssl-ciphers: "DEFAULT:@SECLEVEL=0"

"

I have not hand edited this file - my thought is that it (also) became edited with the command

nmcli connection modify eduroam 802-1x.openssl-ciphers "DEFAULT:@SECLEVEL=0"

I had given (which changed also the file a "corresponding" file at
/run/NetworkManager/system-connections ) .

So I think the run time file is generated based upon what is (permanently stored) at the /etc/netplan corresponding yaml file. Therefore, there is the due configuration for me to use with eduroam even after any reboot.

I should say that now I got all configurations I needed. Thanks to everyone who took time to help me.

Problem after re-enabling bitlocker on Ubuntu 26.04 / Windows 11 dual boot setup https://askubuntu.com/questions/1567735/problem-after-re-enabling-bitlocker-on-ubuntu-26-04-windows-11-dual-boot-setup

I have been using Ubuntu and Windows without issues on a dual boot setup. The Windows drive mounts automatically on startup in Ubuntu, however I want to re-enable BitLocker to encrypt the Windows drive. After re-enabling it, Ubuntu will not start. I get the following message:

You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, or "exit" to continue bootup. Press Enter for system maintenance (or press Control-D to continue):

If I type systemctl reboot nothing happens. If I type exit the same message appears again.

I have disabled Bitlocker again, but still I would prefer to have the Windows drive encrypted because it is a laptop I sometimes travel with.

No focus, no paste in Ubuntu [closed] https://askubuntu.com/questions/1567667/no-focus-no-paste-in-ubuntu

Recently I have problems with my Ubuntu 22.04 using Gnome:

  • I can’t paste with the mouse middle button.
  • New windows didn’t get focus or remained hidden.

I tried several suggestions from the web, but to no avail. I installed 25.04 and 26.04 on the side using the same home directory. I still had the same problems. A new user with a fresh home on any of the installations has no problems. My experiments shows that the problems are associated with the home/.config directory, however my .config is huge and I have difficulties finding the culprit file or files.

GNOME Panel & Activities Overview workspace thumbnails flickering issue https://askubuntu.com/questions/1567665/gnome-panel-activities-overview-workspace-thumbnails-flickering-issue

GNOME Activities Overview workspace thumbnails begin flickering after several hours of uptime on Ubuntu 26.04 LTS with GNOME Shell 50.1 running on Wayland and Intel Alder Lake-N integrated graphics (i915 driver).

System:

  • Ubuntu 26.04 (upgraded from 24.04)
  • GNOME Shell 50.1 / Mutter 50.1
  • Wayland session (no Xorg session available)
  • Intel Alder Lake-N UHD Graphics (i915 driver)
  • Three displays (all 1920×1080 @ 60Hz)

Symptoms:

  • After several hours of uptime, GNOME Activities Overview becomes visually corrupted.
  • Specifically, workspace thumbnails flicker immediately upon entering Overview (Super key or hot corner).
  • The flickering is limited to Overview workspace thumbnails and GNOME top bar. Normal desktop, application windows remain stable and unaffected.
  • Exiting Overview immediately returns the desktop to normal. Logging out and back in resolves the issue temporarily, but it returns in minutes, rebooting it returns after several hours. No GPU resets, hangs, or DRM errors appear in journalctl.

I’ve tried:

  • Kernel parameter: intel_idle.max_cstate=1 Appears to delay or partially change the symptoms, but the issue still occurs.
  • Kernel parameter: i915.enable_dc=0 Initially seemed to reduce symptoms, but the issue still returned.
  • Tested different kernels (including older kernel) No change in long-term behavior.
  • Disabled a couple of third-party GNOME extensions (still using default Ubuntu extensions).

Observations:

  • The issue does not affect application rendering or the desktop outside of Activities Overview.
  • It appears only after extended uptime (hours), not immediately after login.
  • The issue is reproducible across reboots and kernel versions.
  • No relevant errors in journalctl related to i915, DRM, or GPU resets.

Question:

Has anyone seen GNOME Activities Overview workspace thumbnail flickering or corruption on GNOME Shell 50 / Mutter 50 under Wayland, particularly on Intel integrated graphics? Are there known issues, workarounds, or logs that I should investigate further?

Update:

I performed additional testing and found a significant correlation with monitor configuration.

With my original multi-monitor setup (2 ASUS monitors + 1 TCL TV), GNOME Shell produced thousands of repeated errors:

gbm_surface_lock_front_buffer failed Failed to query buffer age, got error 3003

These sessions also exhibited Activities Overview flickering, top-panel flickering, and occasional window-edge artifacts.

I have now tested the system with a single display only (different display: Sony TV over HDMI) and the issue has not reproduced. There is no visible flickering, no rendering corruption, and:

journalctl -b | grep -c "gbm_surface_lock_front_buffer failed" 0

journalctl -b | grep -c "Failed to query buffer age" 0

The issue also reproduced across multiple kernels, including a newer mainline kernel Linux 7.0.12-070012-generic, which makes a pure kernel/i915 explanation seem less likely. Using this mainline kernel the symptoms also started appearing after roughly 10 minutes rather than a few hours.

At this point, the strongest lead appears to be a GNOME Shell/Mutter multi-monitor rendering issue, or an interaction involving multiple outputs.

Can’t boot into an Ubuntu 26.04 live USB https://askubuntu.com/questions/1567269/can-t-boot-into-an-ubuntu-26-04-live-usb

I have got an HP EliteBook 8570W which has a 3rd generation Core i7 processor, an AMD Radeon HD 7700M and 8 GB of DDR3 RAM.

The problem is that I can't boot Ubuntu 26.04 from the live USB. When I boot I see the Ubuntu logo, but it disappears after a few minutes.

Ubuntu 26.04 inaccessible disk https://askubuntu.com/questions/1567128/ubuntu-26-04-inaccessible-disk

I have a ASUS TUF GAMING laptop with two separate nvme each 1TB. On first one windows 11 installed with bitlocker disabled. And on the second one I installed Ubuntu Raccoon. But during installation Ubuntu installer reported bitlocker detected. Anyhow installation finished without any problem. I did not used any encryption either. Just created a user to login. I have created a swap, efi and an ext4 partition. After login, I could not mount the ext4 partition as it prompts for a password!? By the way, I checked the disk and discovered a Microsoft reserved partition in front of queue which was strange. Any idea? Tks

After Update from 24.04 to 26.04: how can I configure my terminal to open in the same directory as other open terminals https://askubuntu.com/questions/1566040/after-update-from-24-04-to-26-04-how-can-i-configure-my-terminal-to-open-in-the

After the latest operating system update I realized that my productivity went down as I was unable to configure my shell to open a new tab console in the same directory as the already opened tab.

How to reproduce:

  • Open a terminal (Ctrl Alt T)
  • cd Downloads
  • Open a new terminal (Ctrl Shift T)
  • New tab opens in ~ but in 24.04 the console opened in ~/Downloads

Any idea how I can get the old behaviour after my update?

The graphical UI has a setting "Preserve Working Directory" with available options: Always - Never - Safe, that does not change the behaviour of the terminal. New tabs open always open in the home directory.

My prompt command variable was used in 24.04 and remains unchanged:

 $ echo $PROMPT_COMMAND setLastCommandState;

Thanks

Solution: switching back to gnome-terminal restored the functionality I worked with in 24.04. Thanks for the help nevertheless! Let's see if ptyxis will add this productivity feature in the future. Nevertheless I love the new Ctrl . to open a terminal from a nautilus window in 26.04.

Ubuntu 24.04 (Noble): Wi-Fi stopped working after kernel upgrade to 6.17.0-14-generic (Intel AX211 / iwlwifi) https://askubuntu.com/questions/1563722/ubuntu-24-04-noble-wi-fi-stopped-working-after-kernel-upgrade-to-6-17-0-14-ge

After upgrading the Linux kernel on Ubuntu (via sudo apt upgrade) to a newer version (in my case 6.17.0-14-generic), Wi-Fi stopped working. The laptop uses an Intel Wi-Fi 6E AX211 adapter with the iwlwifi driver. The device was detected by PCI tools, but the Wi-Fi interface was not usable and the device showed as UNCLAIMED in lshw.

Ubuntu 24.04.2 pinned app shortcut failling on special characters https://askubuntu.com/questions/1545776/ubuntu-24-04-2-pinned-app-shortcut-failling-on-special-characters

I am used to access to my pinned applications with the windows + [0-9] shortcut on Ubuntu 22.04.5.

I recently upgraded my laptop to Ubuntu 24.04.2 LTS and this shortcut only works for non special characters. I am using an AZERTY keyboard and so far, I found that the keys é,è,ç,à (mapped to the keys 2,7,9,0) don't apply the shortcut.

I tried to hold the shift key while applying the shortcut but it only opens a new instance of the selected application instead of navigating to the existing one.

Of course I could use my mouse or the alt + tab shortcut to navigate through my applications, but I find it more precise when I have a bunch of windows opened. Did this behavior happen to anyone?

How do I properly update Python? https://askubuntu.com/questions/1538584/how-do-i-properly-update-python

Detach Terminal crashes all terminal instances https://askubuntu.com/questions/1532175/detach-terminal-crashes-all-terminal-instances

New install. Ubuntu 24.04.1 LTS ~ installed Gimp, Libre Office, and Ink Scape... then added UBS Studio to record the bug.

So, I open a terminal window, and left-click the [+] (top left) to add an additional tab. In most cases if I then right-click that new tab and select Detach Terminal, it will abruptly close all terminal windows that I have open. In some cases this behavior will stop for a few iterations and then start again. Sometimes I have to add two more terminal tabs and select a middle tab among them to try and detach... I have yet to isolate a specific open/close pattern that is 100% reliable to produce this issue. However, it is consistent from a fresh reboot.

Since then I've been looking for a place to report the issue and share the video. I have the video on my google drive to show what I'm seeing happen. Thoughts are welcome.

I'm using Ubuntu 22.04 on a WSLv1 system, which does not support snap:

$ snap list
Interacting with snapd is not yet supported on Windows Subsystem for Linux 1.
This command has been left available for documentation purposes only.

It is only fair because snap list errors out. Is it possible to upgrade to Ubuntu 24.04 by somehow disabling any snap interaction and sidetracking its attempt to do snap list?

Thanks!

How to install without USB stick https://askubuntu.com/questions/1458972/how-to-install-without-usb-stick

I have burned the ubuntu .iso to a USB with Balena etcher and installed Ubuntu to a new SSD with the USB installer.

Now that I have an Ubuntu machine. Is it possible to install to a new SSD from the Ubuntu, without the USB stick? It would be nice not to have to burn a USB stick and be able to outfit a new SSD from an OS (Mac, Windows, or Ubuntu) with an Ubuntu install .iso

How to update firmware correctly https://askubuntu.com/questions/1301801/how-to-update-firmware-correctly

enter image description here I'm looking at the screen and I'm wondering how to update the firmware suggested here, while not using the dock.

My question is on how. Don't I, in order to update the firmware, have to be connected to the dock? If I'm connected to it, am I not using it? This reminds me the days where win95 requested you to connect to the internet to download the drivers for the modem.

2nd (site question): How safe is this? Knowing that the dock is working flawlessly.

chroot: failed to run command '/bin/bash': No such file or directory Ubuntu 18.04 https://askubuntu.com/questions/1217451/chroot-failed-to-run-command-bin-bash-no-such-file-or-directory-ubuntu-18-0

I'm following these instructions to make a debian.img in a ubuntu 18.04 on a virtual box build

  1. On the PC, create a folder and generate a formatted, mountable image.
  2. Install a Debian Buster linux inside the chroot environment with the debootstrap command.
  3. Upload this image (debian.img) to your web server to download it later

The link to the site here

mkdir -p webkey/tutorial
cd webkey/tutorial
dd if=/dev/zero of=debian.img bs=1024 count=614400
sudo mkfs.ext2 -F debian.img
sudo tune2fs -c0 debian.img
mkdir debian
sudo mount -o loop debian.img debian/
sudo debootstrap --verbose --foreign --arch armel buster debian http://ftp.de.debian.org/debian
sudo chroot debian
export LC_ALL=C
debootstrap/debootstrap --second-stage

I have done everything upto 

sudo chroot debian

When i enter this it gives me 

chroot: failed to run command '/bin/bash': No such file or directory

I have read all the posts about chroot and this error none of these solutions does not seem to work for me. Or maybe I am doing something wrong.

Thanks for your time and expertise.

WiFi connection error: deauthenticating by local choice (Reason: 3=DEAUTH_LEAVING) https://askubuntu.com/questions/1180240/wifi-connection-error-deauthenticating-by-local-choice-reason-3-deauth-leavin

I'm encountering a connection issue to my university WiFi network that I cannot solve: when attempting to connect, I get the following message with dmesg -T : 

[ven. oct. 11 12:32:04 2019] wlan0: deauthenticating from X by local choice (Reason: 3=DEAUTH_LEAVING)

This problem has already been pointed out in the forum, but none of the solutions I tried worked:

  • Disabling the powersave for WiFi (in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf set wifi.powersave = 2 ).
  • Changing from NetworkManager to WICD.

  • Adding the following lines to /etc/sysctl.conf:

    net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

None of these worked.

Hard drive is not bootable after a sudden powercut(power interruption) https://askubuntu.com/questions/1118152/hard-drive-is-not-bootable-after-a-sudden-powercutpower-interruption

It's an old Asus laptop that i use sometime for programming. It's battery is dead so i have to be connected to power supply whenever i have to use. Was working fine for the last few years(even with a dead battery). Today while i was working on it, the power plug got dislodged from the socket and the computer instantly shutoff (normal, happened a lot previously). But this time when i tried to start it up, the first time- i could hear the wheezy sound(as usual) but the screen was complete black as if it was shutoff. I gave it some time but didn't see anything on the screen so i rebooted. Now the screen lights up proper (as usual) but i get the 'This is not a bootable disk ...Insert a bootable floppy and press any key...' error on the screen. I tried these at the BIOS setup

  1. enable/disable UEFI

  2. check boot priority ( there's only the hard drive and the dvd drive with the hard drive at the top priority).

No result.

I had a live USB of a Kali distro and i could boot from it (UEFI mode). My hard drive is GPT. It has Ubuntu 16.04 and Lubuntu 18.10 dual booted. Six partition including the sda1(grub_boot). There is no secure boot option in my BIOS setup.

Could anybody suggest :

  1. Where should i look to see whether it is a hardware related problem or just the grub is messed up.

  2. Should i go ahead with a Boot-repair or wait until it am sure where he problem is. Thanks in advance 

                   :Update:

I restarted my system and now, as Ill luck would have it , the screen doesn't even light up though i can hear the fan noise see the power lights. Restarted a dozen of times but to no use so gave up. In the evening, i tried as the last ditch effort but now it's seemed the problem got worse as i could not even hear the fan noise or in fact no noise at all. So couldn't figure out if the POST test is happening or not after pressing the power button. So as a final effort, i started the pc on last time and kept in on for a good 20 minutes and then restarted the System. seems it solved the Dead screen issue and now i can see the pc logo and can enter the BIOS setup. But however, the initial problem still persist so now i am going to do some smart test from the live Kali on flash drive. This is a whole new experience, will update if get any major result.

SSH: Port 22 Connection refused https://askubuntu.com/questions/1072899/ssh-port-22-connection-refused

From Ubuntu 18 lts I'm trying to establish ssh connection with my Kali Linux VirtualBox on the same computer. I've already installed openssh-client and openssh-server on both systems and I'm connected to Internet via ethernet cable. So, I have 'enp2s0' interface (on both systems) which is found in 'ifconfig' and I changed my network ipv4 addresses to static with the same IP addresses I found in 'ifconfig':

In Ubuntu:

IP: 192.168.1.8

In Kali:

IP: 192.168.1.5

Netmask: 255.255.255.0 and Default Gateway: 192.168.1.255 are same on both systems. In VBox settings for Kali I configured network to Bridge connection. I checked ping between these systems and it is ok (64bytes..blahblah). I turned off firewall on both systems:

sudo ufw disable

so it's inactive. The problem is that, I can connect from Kali shell to Ubuntu, but not vice versa where I'm getting the following message:

ssh: connect to host 192.168.1.5 port 22: Connection refused

I also tried with: sudo ufw allow 22 on both and nothing.

sudo ufw ssh enable didn't help.

Accents stop working all of a sudden in Libreoffice https://askubuntu.com/questions/451840/accents-stop-working-all-of-a-sudden-in-libreoffice

I can write characters such as á, é, ó, ã, ê, etc just fine in Kubuntu 14.04.

Even in LibreOffice.

However, if I switch windows from LibreOffice to, say, Chrome or even Dolphin, and then I switch back to LibreOffice, these characters will not register anymore and instead plain a, e, o , a, e will be written, with no accents.

This is very annoying and I've been fiddling with KDE System Settings for the past couple of hours unsuccessfully. I'd really like some help.

Thanks in advance,

mv: Directory not empty https://askubuntu.com/questions/269775/mv-directory-not-empty

I want to move content of a directory within another directory with the same folders.

Here's an example:

I have ./backup which has the directories base and test. Now, I want to move these directories to ./backupArchives.

I use this:

mv ./backup/* ./backupArchives

but I got the error

mv: cannot move './backup/base' to './backupsArchive/base': Directory not empty

I tried using --force, but no luck. Is there a way to move it when folders already exists?

Note: I just want to merge contents, there's no overwriting.
