We have an issue with WiFi drivers on Ubuntu 24.04.
Machine specifications are following:
Dell Pro Max 16 MC16250
Intel WiFi 6E AX211
AX211 driver
Can you please suggest the solution?
I'm using VMware workstation 17 Pro 17.16.4-build.24832109 on my Ubuntu. But everytime I'm starting my Windows VM, I get this error: "vmware could not open /dev/vmmon: no such file or directory. Please make sure that the kernel module vmmon is loaded"
If I run: sudo vmware-modconfig --console --install-all
I get in the end of the output "VIrtual machine monitor" failed to start but some others succeed.
I saw this: https://github.com/codiobert/vmware-vmmon-fix , and it fixed it one time but it means I have to run this script every time I boot my computer which is annoying. How can I fix this?
Moving from Solaris to Ubuntu. I need to display the hostnames of connected ip's as in hosts file instead of ip addresses. Using "who -u""who -m"

Ubuntu 24.04.3 Internet unavailable at turn on. Ethernet connections are OK. Firefox, Brave. after initiating VPN (Air) via (UK server) internet is still unavailable. When I changed the country server to a different location (e.g. Austria) then internet is available. When the country is changed back to my UK physical location, then internet is now available via VPN. Ceased use of the VPN, then internet is now available. Because the VPN handles DNS I guess this is related. How to control or set my VPN?
my external monitor worked well at 144hz all these but today all of sudden, my external monitor is capped to 60hz. I tried everything like adding new mode, but nothing worked. I deleted the nvidia driver and suddenly after a reboot everything works well. But, I need nvidia driver for a project. I want to see if there is any to keep the nvidia driver and have it run at 144hz. (Nvidia running on my laptop dual booted with windows-primary and mok signed in for secure boot on)
Like many users that have migrated to Linux from Windows, my knowledge is wide, but not very deep. After upgrading to Ubuntu 25.10 (from 25.04), then an update to Chrome (sudo apt update; sudo apt upgrade -y), I have been unable to get Chrome to load.

Other than dumping the log, I have uninstalled and reinstalled Chrome (from a download via DPKG) and from Flatpack. I don't recall if I tried Snap or not.
I am currently running Firefox for now on this system (MinisForum MS-01). I have multiple systems running Chrome, so maybe that is the source of the third-party file that's being objected to?
I'm going to ask a lot of questions in this post as I'm new to the Raspberry Pi and somewhat of a novice in Ubuntu. I'm going to use Raspberry Pi OS to create the raid 0 and I need some help on this with the steps, then I'm flashing Ubuntu to said RAID. I also want a better understanding of how the RAID zero works and how the hardware functions with the software. What sets the drive in RAID zero so that the OS can boot once flashed? By the way, I am using a hat. Does the Raspberry Pi have a so-called BIOS or what is the initial startup screen?
Edit: Sorry I'm having issues with what I believe is the power supply with the Pi. I suppose I could use Ubuntu to create the raid once I can get it booted into Ubuntu. It boots in raspberry Pi OS fine just not Ubuntu. If I use the third party power supply I have it boot loops before getting to the os. If I use my laptop to power and boot into Ubuntu it boots into Ubuntu but power cycles once I set up the wifi adapter. I'm waiting on the official power supply in the mail at the moment. And yes, the third-party power adapter does 5.1v at 5 amps.
Where it boot loops:

Yes, I flashed one of the NVMe drives with Ubuntu in Pi OS NOT raid zero yet. I'm using a USB drive to boot into Pi OS, but can use Ubuntu once I can get it booted in Ubuntu. Now I can't boot into the Pi is due to the boot order. I can install an OS on an SD card, but I'm putting a hold on this project until I get the power supply in the mail.
I would like sed do something to each line of a file.
if line is NOT blank, do something, (insert prefix_01 before line text),
if line is blank, (including spaces, tabs or whatever not printable), do something else, (insert prefix_02 before line text).
This is my code:
f1="f1.txt"
printf "line ONE\n \t \nline THREE \t\n" > "$f1"
prefix_01="everything good.. "
prefix_02="NOT good !! "
cat "$f1" | sed -E 's/^/'"$prefix_01"'/'
will produce the following output:
everything good.. line ONE
everything good..
everything good.. line THREE
but I would like to have the following output (with prefix_02 in case of blank lines):
everything good.. line ONE
NOT good !!
everything good.. line THREE
I would like sed to test if line is empty or not, then do action_01 or action_02.
Any help?
I want to add a menuentry in the grub pointing to an SD stick so that I can reinstall and format the whole machine quickly from it next time whenever that is needed.
To this end, I am customize GRUB (/etc/grub.d/40_custom) so that I can boot an Ubuntu Server 24.04 installer from an SD card created using the dd command and formatted using an iso9660 filesystem.
Here is my /etc/grub.d/40_custom file:
menuentry 'Ubuntu Installer (Failing)' {
# Fails with 'error: unknown filesystem'
set root='(hd0,gpt2)'
linux /casper/vmlinuz boot=casper quiet
initrd /casper/initrd
}
During boot,
error: could not find vmlinuz;ls command for (hd0,gpt2) I get unknown filesystem.If anyone had ran into this problem before, please share your experience, that would be much appreciated.
Remarks:
Firefox has not saved credit card numbers for me since I upgraded to the Snap version. When I try to save a credit card number I see messages like this in the syslog:
dbus-daemon[3656]: apparmor="DENIED" operation="dbus_method_call" bus="session" path="/org/freedesktop/secrets" interface="org.freedesktop.DBus.Properties" member="GetAll" mask="send" name=":1.6" pid=5121 label="snap.firefox.firefox" peer_pid=3655 peer_label="unconfined"

I spent about an hour grepping in the AppArmor config files, Googling, and searching Stack Exchange to no avail. What's the secret method to enable this commonly used feature for the snap?
Firefox 144.0.2 Ubuntu 24.04.3 LTS
PS:I am aware of the .deb version, of which I was previously a user. I am hoping we can get the snap version, which Ubuntu is enthusiastically promoting, to work properly so I don't have to go back

Is one of these causing the problem?
I've actually killed docker.service with no help.
I have some QEMU images and those still run.
I can also still run the Android Emulator (from Android Studio).
Also, these VirtualBox VMs recently worked on this same system.
Can anyone give me an idea of why the VirtualBox VMs won't run now?

Is there any way to boot from USB and completely format the hard drive. The reason I want to do this is because my Ubuntu 22.04 is not able to start anymore.

So until yesterday my internet was just working fine, today it doesn't anymore. Nothing has changed in terms of updates or configuration since then.
The PC is still connected to the router. I can ping the router at 192.168.178.1 and even log in to the settings. The router is also connected to the internet, all other computers in the house can access the internet.
I can also ping any device that is in the local network.
I.e. ping -c 2 192.168.178.43 works.
But I cannot seem to connect to any outside IP whatsoever.
When doing ping -c 2 1.1.1.1 or ping -c 2 8.8.8.8 I always get 100% package loss.
Could there be some cached settings perhaps that are suddenly not allowing my router to process the request? Or perhaps my router can't send back any information to my PC anymore?
These are all shots in the dark, as I am relatively new to using Linux, and the problem just mysteriously appeared. No settings have been altered and it was working fine before.
I'd be happy to hear some ideas on how to fix this. I'd rather not re-install the whole system.
I've unsuccessfully been trying to install Ubuntu or Lubuntu for a couple of weekends now. The installation seems to go fine until the end, when I get the "grub bootloader failed to install" error. I dug through the forums and tried all kinds of things, such as re-installing grub, but nothing worked.
Some background info:
I did disable securable boot.
The laptop formally had Windows 10 on it.
I changed the hard disk (since I was planning to upgrade anyway), but this didn't make a difference.
Here is the boot info https://paste.ubuntu.com/p/dt2RZgtT5Y/ Unfortunately, this doesn't tell me very much, so I hope someone else can tell me what's wrong!
I am using the Ubuntu on Windows App running on Windows Subsystem for Linux. So an initial question is if Python virtual environments is supported. Given my as yet limited understanding of Python virtual environments I would think that they are supported in the Ubuntu on Windows App. Here is the version info:
Windows Ubuntu App 1804.2019.521.0
Ubuntu release 18.04 (bionic)
Python Version 3.6.7 (as best I remember this was installed by default).
My motivation for wanting to use venv is this reddit post:
venv by nature of being part of Python itself has access to the internals of Python which means it can do things the right way with far fewer hacks... ...So venv can be thought of virtualenv done right, with the blessing and support of the Python developers.
Similar questions came up when I entered my question, but I didn't find one that solved my problem.
One post:
Since you specifically installed
python3.6instead of Ubuntu's defaultpython3version, which ispython3.5, you have to installpython3.6-venvinstead ofpython3-venvsince that would resolve topython3.5-venv. To do so, you can usesudo apt install python3.6-venv
Another post from 01/2018 said that python3.6 -m venv myvenv worked after reinstalling Python3.6.4. I'm avoiding re-installation for the time being.
Here is what I tried to create a virtual environment:
1) Opened Ubuntu
2) Went to the directory where I want to create the virtual environment.
/home/dgrucza/python-virtual-environments
3) Entered python3 -m venv env This returned the following:
The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv package, recreate your virtual environment.
Failing command: ['/home/dgrucza/python-virtual-environments/evn/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']
4)Tried to install venv by entering sudo apt-get install python-venv After entering my password at the prompt this returned the following:
Reading package lists... Done Building dependency tree Reading state information... Done Package python3-venv is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'python3-venv' has no installation candidate
5) Also tried entering python3.6 -m venv myenv, but received the same message.
The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv package, recreate your virtual environment.
Failing command: ['/home/dgrucza/myenv/bin/python3.6', '-Im', 'ensurepip', '--upgrade', '--default-pip']
I wanted to upgrade from 17.10 to 18.04 but the upgrade failed, I think the reason was that policykit-1 was left unconfigured.
Rebooting did not help and now I am in the emergency console. I found that I have a /var/run/dbus/system_bus_socket, but not /run/dbus/system_bus_socket.
On another machine, I have system_bus_socket in both directories. Any idea what I can do to repair the system?
About a week ago Windows 10 ran its automatic updates and after that I'm unable to boot to ubuntu the way I was doing it (pressing f12 and manually selecting Ubuntu partition). Now it takes me to a black screen saying Unknown Filesystem grub rescue when I try to access it that way.
The partition isn't wiped out and Ubuntu works just fine, but I have to enter a few commands as shown in this video(Non-English) to access it. Would anyone mind helping me to "revert" whatever windows did so I can keep booting to ubuntu manually when I want to with f12 key?
Additional info - I asked this question on Reddit and I was asked
"what is the output of 'fdisk -l' in the terminal?"
This is what shows up:

Here are the steps I follow.
Network Manager → VPN Connections → configure VPN
This opens the Network Connections dialogue. Then,
Add → import saved vpn configuration → choose

This should load my .ovpn configuration, but instead I get a prompt saying

I can still use VPN using the command
sudo openvpn --config ~/openvpn/xxx.conf
is this a bug that needs to be filed?

I read that python 3 is supposed to be the default going forward. Since both 2.7 and 3.4 are there, and have separate commands, how do I not only make sure Python 3 is my default, but that anything I install goes there and is used by it instead of 2.7?
BTW, I tried sudo apt-get python3-virtualenv and got: E: Unable to locate package python3-virtualenv
I'm trying to install ipkg-utils.
However, when I try to install it, it is unable to locate the package
sudo apt-get install ipkg-utils

E: Unable to locate package ipkg-utils
I tried wget https://dev.openwrt.org/log/trunk/tools/ipkg-utils (the repository for ipkg), but it didn't work.
I inherited the code. ipkg was used to distribute and need to build an ipkg archive of a PIC build.
ipkg has been superseded by opkg. I have opkg running ok but haven't built anything yet. What I didn't find out was whether I could create an ipkg archive using opkg.
I've been googling for hours with no joy. Does anyone know how to install ipkg?

I like to run a couple of scripts to automatically install packages and do some configurations on fresh OS installs. I use gnome shell with a few extensions and was thinking of improving my scripts to configure them.
I usually configure the extensions using gnome-shell-extension-prefs or dconf-editor and I know how to edit other schemas from the command line. Example:
gsettings set org.gnome.desktop.background picture-options stretched
But, although I can find and edit the installed extensions under org.gnome.shell.extensions using dconf-editor I can't access them using gsettings since they don't seem to have an assigned schema:
No such schema 'org.gnome.shell.extensions.extname'
The only extensions accessible with gsettings seem to be the ones that came pre-installed.
So, the question is, how can I configure the installed extensions from the command line? Is there any way to assign to gsettings the compiled schemas in ~/.local/share/gnome-shell/extensions/ ? Maybe I'm looking in the wrong direction.
Environment: Ubuntu Gnome 14.04 (Gnome Shell 3.10.4)
Thanks in advance.
I removed the HDD from a Toshiba Computer I bought today and installed a 250GB SSD. After installing it, I immediately installed Ubuntu 14.04 on it from a USB drive. Everything went fine during installation, but when I restarted I got the message
Reboot and select proper Boot device or Insert Boot Media in selected Boot Device and press a key.
That message came up after a nano-second screen that says Checking Media Presence and then No Media Present.
When I reboot using the USB stick, I can see the SSD drive and it has the OS written on it and it looks like it's been partitioned correctly.
Can someone please tell me what I need to do to get my computer to boot up?
Any help or links to good threads would be very helpful. If you have any questions, I would be very happy to help you in helping me.
I'm trying to get NoMachine working on a AWS EC2 instance with 14.04 Trusty Tahr.
I’ve used the instructions from:
When I try to connect from my Mac using NoMachine 4.2.21, I get this error:
The connection with the server was lost.
Error is 54: Connection reset by peer.
When I use the OpenNX 0.16.0.729 client, I get a blank black screen.
Help.
Is there a tool or a way to view the next scheduled job (in the system or at least at the user level) and its time without looking into crontab (crontab -l)?
Imagine that there are 500 different cron jobs with repetitions. I need an "easy" way to know that the job A will be executed after 5 minutes from now.
Recently when I restarted my dual boot Ubuntu (windows 7 and Ubuntu 12.10), all I can see is just my desktop, no dash, no launcher or any topbars. Here is the output of usr/lib/nux/unity_support_test -p:

I'll be really grateful if someone can help me with this problem.
I have a system where all the partitions (/, /home, and swap) are encrypted except for /boot. /boot resides in an external device which also contains a set of encrypted key files used to automatically decrypt all of the partitions. In other words, my desired end result was to have 2-factor authentication using an external device and a password where the password would be entered once during boot and the boot scripts would use the password to decrypt all of the partitions.
I'm a newbie to Ubuntu (and Linux in general), but I did some trial and error modifying the various scripts found in initrd.img using update-initramfs. The cryptroot script seemed to be doing all the work mounting the partitions at first, but after some experimenting, it appears that it is only responsible for decrypting the root file system. I had modified a string in the script changing Enter the passphrase to simply Password, which appeared to work when decrypting the root file system, but used the old prompt again for decrypting the next partition. In other words, this is what I'm getting:
I think Ubuntu might be running another copy of the cryptroot script somewhere to decrypt all the other partitions after root, but I don't know what else to modify.
I'm currently running Ubuntu 12.04 and want to completely format my laptop so I can install Windows 7 (replace Ubuntu).
When I put in my bootable USB with the OS it just shows a black screen with a white blinking cursor on the top left corner. I wait for hours (to be specific 5 whole hours) waiting for something to happen but I get nothing, so I pull out the USB and my Ubuntu 12.04 loads up.
Repeated this several times with putting different boot priority options on top-est that relate to USB but the results are same. I go and visit some sites on the net like this http://www.techspot.com/community/topics/cant-replace-ubuntu-with-windows.175716/ that say I have to zero out my hard drive.
My question is how?
Note: Erasing out all my data is no problem cause I have nothing important to backup.
If I have to lose my primary OS (Ubuntu 12.04) in the process I am ready to as my aim is just to install Windows 7 successfully. Please don't answer that there is something wrong with my USB or my USB reader/port/hardware or the content inside the USB cause they all works fine on my brothers PC as it boots up flawlessly.
