So I noticed that a similar question has been asked before, but they just give a list of different possible application directories where the .desktop files are found.

Where is the location of application shortcuts in Gnome?

Is there an environment variable or a config file or some place where these directories are stored? I mean, I'm assuming GNOME isn't just exhaustively searching the entire disk, so the list has to be somewhere, right?

Older Ubuntu versions(up to maybe 16.04) had a right click option to write ISOs to DVD(maybe USB)

Newer versions including 24.04 do not seem to have that option anymore. Need to open Start up Disk or similar.

Did the write to disk option have the ability to write to USB and can we add it back to right click options?

It was nice if just doing downloaded movies/tv shows to DVD also.

I accidentally deleted the grub2 files. Every time I turn on my computer, I go to grub rescue. Commands like help or boot do not work. My operating system is Windows 10. How can I exit grub rescue?

I have an Ubuntu 24 server inside a home/office network. I need reliable remote access (SSH and occasional remote desktop) from the internet, but my router does not allow opening or forwarding external ports (I either don't have access to change router settings, UPnP is disabled, or my ISP places the connection behind CGNAT).

What I want:

• Be able to SSH into the Ubuntu server from outside the LAN.
• Ideally have an option for secure, persistent access (not a one-off hack).
• Prefer open-source / low-cost solutions, but I’m open to paid services if they are simple and secure.

What I’ve tried so far:

• Attempted standard port forwarding on the router — blocked / not possible.
• Confirmed the server is reachable inside the LAN (SSH works locally).
• I don’t have a static public IP and suspect I might be behind CGNAT.

Constraints / notes:

• I can run additional services/clients on the Ubuntu server.
• I can rent a small VPS if needed.
• Security is important — I want to avoid exposing weak services directly to the internet.

Questions:

1. What are the practical, secure ways to get remote access in this scenario?
2. Which approaches are easiest to set up and maintain for remote SSH access?
3. What are the security trade-offs for each approach?

Possible options I’ve heard about (please comment on pros/cons):

• Reverse SSH tunnel (server opens an SSH connection to a public machine / VPS).
• autossh + systemd to keep the tunnel persistent.
• Using a small VPS + WireGuard / OpenVPN to create a site-to-site tunnel.
• Using third-party tunneling services like ngrok / localtunnel.

If more details are needed (router model, exact network setup, whether I have a spare VPS), I can provide them, but I’d like recommendations that work when you cannot open ports and might be behind CGNAT.

i ran sudo snap remove docker without --purge flag so it was stuck and i Ctrl C'd it.

Now i have:

31 Undo today at 17:19 UTC - Remove "docker" snap

which is mess cause now i can't remove it at all, aborting id leads to nothing, restart snapd - same stuff.

all i have now is

~$ sudo snap remove --terminate --purge docker

error: snap "docker" has "remove-snap" change in progress

How can I force snap to delete this snap?

After update from Ubuntu 25.04 to 25.10, there is something wrong with locales and / or the date command:

Normally date should output (as in 25.04):

$ LC_TIME=en_GB.UTF-8 date 
Fri  7 Nov 19:29:29 +03 2025

But, in 25.10 it outputs:

$ LC_TIME=en_GB.UTF-8 date 
Fri Nov  7 19:31:06 +03 2025

like the US (default) format.

I also ran the following, but nothing changed:

$ sudo locale-gen --purge

$ LC_TIME=en_GB.UTF-8 date 
Fri Nov  7 19:34:20 +03 2025

How can I properly format the output of date command according to the active locale (e.g. en_GB)?

The cause of the problem seems to be the /usr/lib/cargo/bin/coreutils/date command to which the date command is linked by default. Because:

$ LC_TIME=en_GB.UTF-8 /snap/core20/2669/usr/bin/date
Fri  7 Nov 21:13:50 +03 2025

works OK.

So, my question is possibly related to this answer. However, I am searching for another, more simplistic solution.

I'm building a Laravel 12 project using FrankenPHP in a Docker container. After multiple rebuilds and tweaking composer.json requirements. I started hitting this error whenever I run any php artisan command:

php artisan

In Auth.php line 93:
                                                                                     
  In order to use the Auth::routes() method, please install the laravel/ui package.

Now this problem occurs even when running any php artisan command locally.
ubuntu 22.04

I also have the following IPv6 related settings in /etc/sysctl.conf

net.ipv6.conf.all.accept_ra=2
net.ipv6.conf.all.accept_redirects=0
net.ipv6.conf.all.accept_source_route=0

IPv4 address has been configured, but only the IPv6 LLA (FE80::/10) of the interface has been configured despite the following packets exchanged on the interface with the router:

• Router Solicitation from the host to the router

• Router Advertisement from the router containing the right prefix information which should be used to form the IPv6 global unicast address (2000::/3)

I also see from the wireshark trace a Neighbor Solicitation for the LLA address, but nothing for the global address. Afterwards, I keep seeing Router Advertisements (which is expected) but no other Router Solicitation.

It's like NetworkManager receives all the information it needs for the global address, but does not act on it.

We can see in the log the dhcp6 (enp1s0): activation: beginning transaction, but it never ends.

If I try to force renewing the addresses, the result is the same:

nmcli connection down enp1s0 && nmcli connection up enp1s0

What is going on?

How to debug this issue more deeply?

I think it updated the nvidia driver for my 1050 card. The driver appears to be the same one in use for my other machine running a 3050 which at the same time started locking up after shutting down virtualbox. I see a new driver listed which makes note of fixing this problem which was likely introduced with this last driver update. But I have no idea what is going on with the server. BIOS screen is in high res, but from grub thru login screen it just stays at 640x480 and the wired ethernet is not working nor is the server software running which is installed on this machine. I'm at a loss. Guessing I have to start over and reinstall.

When my battery in 24.04lts gets to say 15%, how do I get it to automatically hibernate?

My 72 year old brain sometimes forgets to cut on power to my laptop when I launch Linux, and I've worked away at something, and stepped away for some reason, only to have the battery go dead and it just shuts down dumping all the hard work my disabled and feeble butt did - be nice if it just hibernated instead so my work is saved... but how?

When I create and use a link to a frequently-used directory in Ubuntu 24.04 it works great, except that when I want to copy the directory path from Files for some other purpose, I don't get the actual directory path, but one that reflects use of the link (which is also how Nautilus/Files displays the location).

In the attached image, I've used a link to access a directory I'm currently in/out of regularly, copied the path from Files and pasted it into a Text Editor window to illustrate.

Is this by design? If so, what's behind it?

Is there a way to have Files display the actual location vs. the link path when one arrives somewhere by link?

Is there anyone who gets this type of answer while opening there Ubuntu 22.04 on Windows, and how can I fix it so I can continue working?

I'm trying to find the actual IP address (IPv4 or IPv6) of printers configured via CUPS on my Ubuntu system.

When I run:

lpstat -v

I get:

device for HP_DeskJet: ipps://HP1234.local:631/ipp/print
device for HP_DeskJet_series: implicitclass://HP_DeskJet_1234_series/

These URIs don't give me the bare IP address. I want to know the actual IP address the printer is using on the network.

Is there a way to resolve .local hostnames or implicit classes to their IP addresses? Or is there a CUPS command or config file that shows the raw IP?

I'm using Ubuntu 22.04 with CUPS installed and managing printers via the default system tools.

I wonder if anyone can help?

I've just got a new laptop (an HP Omnibook X) which came pre-installed with Windows 11.

I'm trying to install Ubuntu 25.10 and dual boot.

First time around, everything went smoothly and it all worked fine.

But then I run some Windows updates from HP and the dual boot menu disappeared when I restarted.

I realise now it was probably a mistake but I decided to just reinstall Ubuntu again to get the dual boot menu working again.

But now I'm getting an error partway through the install. I've re-tried several times now but keep getting the error. I tried re-formatting the partition of the disk where Ubuntu installed last time, but don't think it deleted anything because the install recognised that there was a previous installation of Ubuntu on the disk.

Here's a chunk of the last part of the log. Help/assistance gratefully received

In Ubuntu, you can now set an accent color in 'settings -> appearance', but I would like to change that via terminal too (to write a global theme switch script, that would change accent colors for several applications).

I am currently using Ubuntu 25.04, but I think it is the same at least since 24.10

The settings I mean: appearance settings

Did a bit of searching around for answers, but nothing seemed to point to this oddity.

I have an Ubuntu 24.04 server that currently has one QEMU/KVM running on it.

I just installed a 2.5Gbit Network interface into the machine and did some network speed testing.

Going directly to the host machine, my speed is 900+ Mbit, which is about what I get going through the gigabit adaptor.

If I speed test to the VM running on that same server, my speed is 2300Mbit.

I don't have ethernet cable plugged into any other NIC, so it isn't a routing difference.

Any thoughts on this?

I forgot to mention, the server is using SSD's so I don't believe it is a hard drive speed issue.

Scrolling up or down with the arrow keys on Ubuntu 24.04 suddenly stopped working. Each key press moves the page only a line or two. Also, holding down the delete key now deletes only one character until pressing the key another time. This behavior is the same in different browsers. In settings > mouse and keyboard, I don't see anywhere to change this. The keyboard on this ThinkPad T440 always performed as expected before. Where can I reset it? Please and thank you. Edit: Looking over similar questions gave me the idea to experiment with the Fn key. Pressing Alt + Fn restored normal functioning of the arrow keys, but I can still delete only one character at a time. As I was composing this post I tried to see if doing something with the Fn key would fix the delete function too. I couldn't find any combination of keys to do that, and now, arrow scrolling doesn't work either. I can't duplicate whatever I did before. Please help.

I have the following lines in my .bashrc to support colors in man pages:

# Colored man pages
export LESS_TERMCAP_mb=$'\e[1;32m'
export LESS_TERMCAP_md=$'\e[1;32m'
export LESS_TERMCAP_me=$'\e[0m'
export LESS_TERMCAP_se=$'\e[0m'
export LESS_TERMCAP_so=$'\e[01;33m'
export LESS_TERMCAP_ue=$'\e[0m'
export LESS_TERMCAP_us=$'\e[1;4;31m'

It worked out of the box right after installation on Ubuntu 20 and 22. However, after fresh installation of Ubuntu 2024, the colors in man pages are gone. What is interesting, if I print TERMCAP environment variables, it looks like they are empty:

[user@host ~] env | grep TERM
COLORTERM=truecolor
LESS_TERMCAP_se=
LESS_TERMCAP_so=
TERM=xterm-256color
LESS_TERMCAP_mb=
LESS_TERMCAP_me=
LESS_TERMCAP_md=
LESS_TERMCAP_ue=
LESS_TERMCAP_us=

There was a lot of rumour about TPM base disk encryption available on Ubuntu 23.10, but looks like all articles meant installation process.

Is it possible to retrofit TPM based encryption (effectively the key typing stage) on the upgraded OS instance with already encrypted drives? I'd like to stop typing password every time the system boots.

I have a problem that is driving me crazy and could not find a solution in the web jet, so I would appreciate if anyone can point me in the right direction. I have a laptop MSI prestige running kubuntu 22.04. I had to install kernel 5.18 so that the wifi work. I also installed nvidia drivers 515.48 (this solved some heating problems that I had). So now it seems that everything runs good, but for a small random problem: plasma does not always start automatically. Usually, when the computer boots sddm fails so I have to change to another console, restart sddm and everything works fine. That is the usual procedure, but sometimes sddm starts good by itself on boot and sometimes everything is stuck and I have to reboot the computer. The error I see in syslo is

sddm[1002]: Failed to read display number from pipe 
sddm[1002]: Could not start Display server on vt 1

Some of the parameters I have in grub that I read could help:

ibt=off rd.driver.blacklist=nouveau nvidia-drm.modeset=1

I read that it could be related to the fact sddm is launched prior to GPU being properly initialised, but not sure if it is really that and how to correct it.

So if anyone has some ideas, that would be great

journalctl -b0 -u sddm.service

gives

I tried to install MSSQL-Server using Microsoft's guide but I get this error during the installation, I tried Synaptic but it did not work, I browsed trough Stackexchange running some terminal codes but it did not help either, here is the error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:

And here is the other error when I try to update:

I have a few remote ubuntu servers which I don't have a physical access to them. I want to ssh , all of them are saying that the state is filtered on port 22. I have just their Ip address, by using ssh command, I SSH to them, but it is not possible because their port 22 is filtered. how can I access the servers , or reset the filtered port to open it? or any idea

Aims

• Goal of this post: Figure out what xorg.conf configurations are necessary to use each of my dual monitors as a separate X screen.
• Intermediate goal for this post: Figure out why I cannot start X with my manual xorg.conf configuration.
• Success metric: When I can launch xeyes or other X11 apps in a script which specifies which of my monitors they appear on.
• Ultimate purpose: To start LXC GUI containers (meaning a full desktop) such that they appear fullscreen on a chosen monitor. I wish to be able to share a keyboard and move a cursor between the monitors, but not move windows.

My system

• Ubuntu Server 20.04, Nvidia GT 710 video card. Driver is nvidia-dkms-470-server. The connections I am using are HDMI and DVI.
• There are other video cards present on the system, but they are aliased and will be used for passthrough purposes. I see no reason why this should be relevant, but video drivers have surprised me before.

Expected behavior:

• When I run startx &, X should start normally, and then I should be able to open xeyes on either screen 0 or 1 by using DISPLAY=:0.0 or DISPLAY=:0.1 respectively.

Actual behavior:

• I cannot start X, with "no screens found".

• Judging by the logs, xf86OpenConsole might be related to the problem, but I have no idea what that is.

• This is Xorg.0.log after I try sudo startx &.

First attempts

• I made my xorg.conf based on this: https://download.nvidia.com/XFree86/Linux-x86_64/304.137/README/configmultxscreens.html
• I suspect there is something more I need in the monitors section of xorg.conf, but I am not sure what it is.
• I feel like the monitors should reference the Screen definitions in some way, but my random guesses about how to do that have been fruitless.
• I am finding it difficult to adapt the xorg.conf examples I have found to my specific circumstances. I don't know what is mandatory based on my hardware or distro/version.
• /etc/X11/xorg.conf:

Edit: One additional note: I have tried supplying the PCI IDs under the "Device" section like BusID "PCI:44:0:0". That actually seems to be the cause of my earlier problem with X not starting with:

[   229.284] (WW) xf86OpenConsole: setpgid failed: Operation not permitted
[   229.284] (WW) xf86OpenConsole: setsid failed: Operation not permitted

Yet another update

I removed the PCI BusID specification from the Device section of xorg.conf, as for some reason it prevented me from starting X with the xf86OpenConsole errors mentioned above. However I did notice that Nvidias more recent documentation suggests using a ServerLayout section. I added the second screen to this section, and it did change the output of xrandr, but not in the way I wanted. It still only mentions Screen0, but now there is no info about my HDMI monitor (although I have a cursor on it). This is now the output of xrandr:

~$ sudo xrandr -q
Screen 0: minimum 8 x 8, current 1600 x 1200, maximum 16384 x 16384
VGA-0 disconnected primary (normal left inverted right x axis y axis)
DVI-D-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 367mm x 275mm
   1600x1200     60.00*+
   1280x1024     75.02    60.02  
   1152x864      75.00  
   1024x768      75.03    60.00

   640x480       75.00    59.94  

And my xorg.conf currently looks like this:

Edit: One more thing: I tried adding Option "ZaphodHeads" to my Device sections, but that did not help. Perhaps it isn't what I wanted, or maybe I didn't configure it correctly, I don't know.

I deleted the Ubuntu 64bit partition from Windows 10 to extend its size and I am trying to reinstall it on my PC. The problem is, Ubuntu installer is neither detecting the windows installation nor the partitions I've made on my hard disk using windows. The installer shows an empty hard disk (no partitions) where I can install Ubuntu. I'm afraid if I continue to install I might break the existing partitions and lose my files. But the partition manager "Gparted" is showing all the existing partitions correctly. Only the installer is not able to detect the partitions.

I made a bootable USB drive for Ubuntu installation using "Universal USB Installer".

Here is the output of sudo parted /dev/sda print and sudo gdisk -l /dev/sda

I cannot boot to Windows nor install Ubuntu since the partitions aren't detected. Should I convert MBR partitions to GPT so they are detected during the installation? Is it doable without losing my data?

Anyone has a solution to this?

On initial install, my headset wasn't identified/found at all. After adding the missing middleware and setting AutoEnable=true in /etc/bluetooth/main.conf, the headset was identified and I was able to use it once. But the very next day I tried to reconnect, and it doesn't work any longer. The device connects successfully, I can hear a notification in the headset, and them it disconnects shortly afterwards(3-5 seconds).

What should I try next?

I'm having a problem with CodeBlocks.

I can't run any C++ code and every time i try, I get the following error in terminal

Process returned 126 (0x7E)`

I googled it and found this link: http://www.thestudentroom.co.uk/showthread.php?t=1737736

sudo nano /etc/fstab

• find the line which says NTFS somewhere on it.
• find the part of this line which says "user"- it's under the header
• change "user" to "user,exec"- remove any "noexec"s
• Ctrl-X and save when asked

But when i followed the first steps, fstab didn't appear so I can't follow the next steps required to fix the problem.

How can I fix this problem in a simplest way? How should i open fstab that is required?

I just installed Ubuntu 13.04 on my new Lenovo Ideapad using the live USB. My problem is that I cannot connect to my wireless network. My wireless adapter is recognized as Atheros Communications Inc AR9285 Wireless network adapter.

Help please with a little printer probem.

I am using a Sharp-MX-2310U printer on the network with Ubuntu 12.10. Followed all the normal setup and looking at cups localhost:631/printers/ I see the printer but no print jobs are printed and /var/spool/cups just keeps on filling with unfinished jobs.

The printer properties display the ink status etc so I do have connection to the printer but localhost:631/printers/ shows:

SHARP-MX-2310U SHARP MX-2310U Office Sharp MX-2300N Foomatic/pxlcolor (recommended) Idle - "Waiting for printer to finish."

Looking in localhost:631/admin/log/error_log I get a number of errors but nothing that is obvious.

I would like to try a different video display driver, but I'm not sure which one I'm currently using.

What's the simple way to see what driver my system is using currently?
