SSD is completely deleted, only Ubuntu is on.
Problem: No audio
Do I need to download drivers?
The keyboard that I use in LibreOffice Writer on Ubuntu does not correct words automatically. The keyboard for krutidev is available here
Another similar keyboard is Remington and autocorrect is working very well in that. Even if both the keyboards look the same, LibreOffice Writer does not consider them the same when it comes to correcting words automatically.
https://github.com/mike-fabian/m17n-db/blob/master/MIM/mr-remington.mim
Is there any reason why krutidev keyboard does not work with autocorrect in Writer?
I'm clawing my way to making a Jellyfin server on Ubuntu. So I suspect I'll probably post here again, possibly later today.

I would like sed do 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/^/'"$prefix_01"'/'
will produce the following output:
everything good.. line ONE
everything good..
everything good.. line THREE
but I would like to have the following output (with prefix_02 in case of blank lines):
everything good.. line ONE
NOT good !!
everything good.. line THREE
I would like sed to test if line is empty or not, then do action_01 or action_02.
Any help?
yesterday i updated my Ubuntu 25.0. Since then my space bar doesn't work. I try to clean it, but it doesn't seem in poor shape at all, it was pretty OK, with no sings hardware damage. I wrote this question recurring to keyboard on screen accessibility toll, witch might indicate that its not a software problem and i am miss correlating events . Can someone help me, please?
I am trying to dual boot Ubuntu 25.10 on my Lenovo Thinkpad T480 alongside Windows. The installation seems to complete successfully, but the laptop always boots directly into Windows. The GRUB menu never appears. Here are my system details and the steps I've taken:
Laptop: Lenovo Thinkpad T480
OS: Ubuntu 25.10 (dual boot)
BIOS Mode: UEFI
Secure Boot: disabled
indows Fast Startup: disabled
Partitioning: I used the "Something Else" (manual partitioning) option during setup, following a guide similar to this one. My EFI partition is nvme0n1p1, and I have separate partitions for /, /home, /boot, /var, etc. The core problem is that the UEFI boot entry for Ubuntu is not being created.
fdisk -l output:$ sudo fdisk -l

I ran the Boot-Repair utility from the live session. It failed to add the entry and gave me this specific, critical message:
Locked-NVram detected. Please do not forget to make your UEFI firmware boot on the Ubuntu 25.10 entry (nvme0n1p1/efi/ubuntu/grubx64.efi file)
This "Locked-NVram" seems to be the entire problem. Is there a hidden BIOS setting I need to find that "unlocks" the NVRAM for new UEFI entries? What should I do?
I have an old MacBook that is out of Apple support, so I installed Ubuntu 24.04.03 LTS rather than chucking it out. On a Mac the Cmd + c and Cmd + v keys are the standard keyboard cut and paste. Is there any way to map these commands to allow this functionality?
I tried in Settings -> Keyboard -> Keyboard Shortcuts, but I think this is really for mapping an application to a keyboard shortcut.
I am a beginner in Ubuntu, I decided to stick to me current computer. Windows 11 told me to change it, but I won’t… It works just fine ! So I decided to change and learn from every steps, even the smallest, using Ubuntu now (Ubuntu 24.04.3 LTS).
Here is my problem. I get an AppImage of the app SuperSlicer. https://github.com/supermerill/SuperSlicer/releases/tag/2.5.59.13 Prior to downloading it, I decided to install the Synaptic package manager, as I read a recommendation for it (just to know it). Everything works fine in the app when running. Except... the icon in the task bar when I launch the SuperSlicer app. The pinned icon on the bar is correct.
But the icon of the app after launching is a kind of a generic one AND there is not this little red dot (or dots when the app is running multiple times) just right of the pinned icon (as for Firefox in this example). This should actually be the only mark indicating that the app is running looking at the bar and that is the behavior I am looking for.
Generic icon of the app when launched:
I read a bit about this problem and learn that it could come from the .desktop file. But I do not see any trouble in it. Below is the icons location I found and the .desktop file content.

Currently, this PC has Ubuntu 20.04 LTS in the 256 GB ext4 partition, as shown below, dual booting with Windows 10. This works well, using GRUB to select OS when booting.
In the meanwhile, I've set up Ubuntu 24.04 LTS on an external SSD, using 140 GB, as shown below.
The OS and software on the external SSD is up-to-date, customized to my preferences, and works well.
Though I can switch OS by plugging in the USB drive and changing boot order from the PC's firmware menu, my goal is to replace Ubuntu 20.04 with 24.04, still dual booting with Windows (kept for a few legacy apps, such as current and future tax software). Though I could delete the 256 GB ext4 partition of the internal, making the end of the drive unallocated, and then copy to it the 140 GB Ubuntu 24.04 ext4 partition of the external drive, I'm concerned if GRUB will find either Windows or Ubuntu partitions.
Would simply copying over the 24.04 ext4 partition work, or is there a better way to do this?
For various reasons, I'd prefer not upgrading to 22.04 and then 24.04, among them being that the OS and software on the external drive works as-is, and I have cloned it successfully to two other machines that boot Ubuntu alone.
Had php-fpm on Ubuntu 20.04, switched to Xubuntu 24.04.
First, PHP seems to ignore .user.ini. Every thing thing has been checked: all configuration files in /etc and access rights on all the path going to the .user.ini file. It was working normally with Ubuntu 20.04. php_info() confirms the values set in .user.ini are ignored. More strange to come.
Tried with a local php.ini instead: not better.
Tried to set the configuration flags and value in .htaccess although it seems to be obsoleted now (unless I’m wrong): php_info shows the good local values, however entirely ignores it. Ex. it says display_errors is On, but it does not apply, similarly with log_errors and error_log, nothing is written to the specified error log, although php_info() says it knows the values. This is not an issue with group/owner/permissions, it was checked and it is the same as was with Ubuntu 20.04, and was applying fine. PHP and Apache had been restarted many times.
Again weirder: if I remove the lines from .htaccess it writes to another error log which is specified globally. If it is set locally, it says it knows it, but write to no error log file, either the local or the global one, it makes it ignore error logging entirely.
Searched the web many days for that, tired of it, though it was working with .htaccess (although would prefer .user.ini to be better organized), but it just shows the value and ignores it.
It must be either something obvious I am missing or a weird corner case no body or very few knows; searching and reading multiple pages line by line did not help.
It seems it works only if set globally under /etc/php/8.3/.
What would be nice, would be a way to debug step by step what PHP is doing and where it fails, but I don’t how to do it or even if it can be done.
Versions:
Checking Apache version, I noticed I had to invoke apache2ctl to get it right, because apache2 returned an error about a missing APACHE_RUN_DIR environement variable being not defined. But I really have to sudo service apache2 restart because apache2ctl is not the name of a service. I feel to guess this issue is not related, while still mentioned in case it may be meaningful.
Update 2025-09-14:
The only way I could get PHP use a per site INI file, is adding a directive for it in the virtual host:
<VirtualHost 127.0.0.2:80>
ServerName ....
...
PHPINIDir /home/xxxx/.../public_html/.php.ini
</VirtualHost>
(idea after this french web-site: mettre un php.ini spécifique pour un VirtualHost)
Each time .php.ini is modified, a sudo service apache2 restart is required.
It still reads the INI files in /etc so it does not break the configuration. php_info() now sees all configurable properties as “local value” and “master value” at the same time. Ex. the value for error_log is the same for both. I made this an opportunity to rename .user.ini into .php.ini, which is more meaningful. Unlike php.ini (without a leading dot), it will apply on all directories of the virtual host, with no need to copy it in each directory.
When I said it was writing to another error log, it was the one defined for Apache in the same virtual host, so it was not really a PHP error log file, rather an Apache error log file. This means when PHP was not writing to it anymore, it was not logging error via Apache anymore, I guess.
The practical case is solved, good enough to be said better than a mere workaround, but the initial issue is not, which is to explain why PHP behave so strangely.
Be careful with comments, which may break the configuration file. It's better to have few or none.
I have a dual-boot setup with Windows 11 (BitLocker off) and Ubuntu 22.04 (LUKS encrypted). I need to upgrade to 24.04. The default upgrade won't work because the /boot partition is too small and cannot be resized easily because it's encrypted. Either way, I have already formatted the / partition and am trying to do an encrypted Ubuntu 24.04 install.
I am following these steps:
At this step, I expect to set the passphrase for the encryption, but I don't get any option for that. I have already run the full installer once and have got the fresh Ubuntu 24.04 installation working, however, it's not encrypted.
Can someone please guide me on the encrypted setup? I am fine formatting the partition again as there is no data.

But I cannot open it in windows, it writes me: You do not have permissions to access \myubuntu\media
How to share it for any windows user? P.S. smb.config contains

How to enable a specific port on Ubuntu version 22 so that it is accessible to outside world?
I am already logged into the server through ssh using port 22 and able to successfully execute all the commands.
I have enabled the ufw firewall and also enabled ports 22, 80 and 22786.
Both 22 and 80 are fine and accessible but not able to access 22786 from outside world.
Do I need to change some other firewall settings to enable port 22786 ?

I installed Nginx manually and was able to access it using http://ipaddress
But when I check through this online tool (https://www.yougetsignal.com/tools/open-ports/), it shows both 22 and '80' ports are enabled but 22786 is closed.
22 port was already open when I got this host and 80 got enabled after I installed Nginx and added it to ufw using sudo ufw allow 80 command. I used sudo ufw allow 22786 command to enable this port too but no luck.
I don't hate snap as much as some people but I do usually prefer not to use it so it's really annoying when I: apt install and it just installs a snap without asking, is there a way I can prevent that, either by making it ask or by just failing.
I don't want to remove snap entirely, just stop apt from installing snaps automatically or at all.
While getting Firefox to use KDE / Plasma dialogs was not straightforward, following this link and rebooting my machine got it working.
Thunderbird seems to be another kind of animal though.
Copying the thunderbird.desktop file to my home directory does not help. Editing the menu entry to look like GTK_USE_PORTAL=1 thunderbird does not help.
I am able to get the plasma dialogs by running the above command from terminal, which then throws lots of errors:
~$ GTK_USE_PORTAL=1 thunderbird
[calBackendLoader] Using Thunderbird's libical backend

Thunderbird eventually opens, asking me to select system integration. Then it will use Plasma dialogs, but on next startup it will return to its default dialog.
So, how do I get Thunderbird to use KDE / Plasma file dialogs every time?
First question here, please let me know if i'm inaccurate.
I'm trying to install ubuntu 18 in dual boot with windows 10. I made my usb with rufus in gpt mode an i can boot on it but when i click on install ubuntu or try ubuntu without installing i obtain a black screen with the following output :
error : invalid buffer alignment -1070023623
error : you need to load the kernel first
Press any key to continue...
So i go into grub command-line and whichever command i use i obtain the following output :
error : invalide buffer alignment -1070023599
except with the command set which allows me to see a long lists of options, here are 4 of them as example:
?=29
cmdpath=(hd0,gpt1)/EFI/BOOT
prefix=(hd0,gpt1)/boot/grub
root=hd0,gpt1
Do you have any idea how to fix this so i can finish my install ?
Thanks guys !

MySQL server was running fine last night, but this morning, when I tried to hit the Bugzilla server, I found it down. I tried to start it, but I get:

I have done a few google searches and found a bunch of questions. I tried some of the answers, but the server is still down. I have plenty of space,

I'm trying to write a program that transfers data to my device. I'm using libusb. I had many problems to install its package in both 32 & 64 bit edition of Ubuntu 16 LTS. Commands for installation:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libusb-1.0-0-dev
sudo apt-get install libusb-1.0-0-dbg
also tried: http://www.linuxfromscratch.org/blfs/view/svn/general/libusb.html
"dpkg -l libusb*" in Ubuntu 64 bit; shows that it has been installed while 32 bit one announces "no such package...".
Compiling command:
sudo gcc -g -o usbtest usbtest.c -lusb-1.0
In Ubuntu 64 bit it compiled while in 32 bit one, following note appeared:
/usr/bin/ld: cannot find -lusb-1.0
collect2: error: ld returned 1 exit status
but I was sure that it exist then I tried following command and it compiled without any error.
sudo gcc -g -o usbtest usbtest.c -L/usr/local/lib -lusb-1.0
at the end when I execute my program, it can not find my device in other words can not open the device. following presents debugging procedure in Ubuntu (32 & 64 bit):
141 int r = 1;

I don't have any idea what should I do.
I'm not sure how to install my Huion H610 Pro tablet. It's completely unresponsive when I plug it in. I've found things on using the DIGImend software, but the installation and setup directions are less than clear. I don't understand what I'm doing in the least, and I'm finding no guides that are comprehensible for someone new to Ubuntu.
I use Ubuntu GNOME specifically.
This laptop has an i7 processor and a discrete Nvidia GTX 960M card. I'm trying to run Gnome Shell. Has anyone got this working really well? And if so, how?
My research/trials on Ubuntu Gnome 16.04, installed in UEFI mode. Note: stock Ubuntu with Unity works fine with/without proprietary drivers.
The nouveau drivers work for everything (i.e. I get Gnome up with the full resolution, touch works) except HDMI. When I plug in a FHD external monitor (VGA or HDMI), either I get what looks like a proper image on the external screen but with a flashy-mostly-black laptop display, or I get static images on both screens and a complete hang that you have to hard-boot from.
Both the 'tested' and the 'updates' versions work the same way: they don't.
On booting I get a console screen in UHD that flashes on and off and does not accept keyboard input, most of the time.
Gnome shell runs with both intel and nvidia graphics if it is started by lightdm, however it still kills the system if an external monitor is plugged in.
Bluetooth not working with Atheros AR9462 chip on Utopic / 3.16 kernel
I need assistance from the community, please. I seem to have stumbled upon a big issue with support for bluetooth on these Atheros chipsets. Unfortunately I have only a light grasp of what I am doing when I start working with kernel modules.
I purchased a Acer V3 Nitro laptop (VN7-791G-77HR) in December and installed Utopic Unicorn 14.10 x86_64. Laptop uses a Atheros AR9462 wifi/bt combo chipset.
Bluetooth is not working properly. I cannot detect any devices in pairing mode. Everything else is working fine including wifi. BT works fine in Windows 8.1 on this machine.
Gnome-bluetooth applet opens and seems to indicate the bluetooth is enabled. When I add a device it just searches for 30 seconds and then closes with no device ever found.
Here is output from hcitool and rfkill.

I installed dkms module and copied some '.dfu' files as listed in this linux-firmware Bug # 1394368
Here is the output of dkms status showing the ar9462/1.5.1 module installed.
tkitz@LUAN:~$ sudo dkms status
[sudo] password for tkitz:

I am pretty much stuck at this point. Any help would be appreciated. If nothing else, I am sure I will learn a bit more about dkms and modprobe. :-)

Can someone help me with this?
I have a virtually hosted ubuntu server 12.04 on which I installed Unity desktop. It all works fine except the only keyboard option I have is "US". This could be due to the fact that ubuntu server was installed with US keyboard (by the virtual machine provider).
I want the keyboard layout to be Canadian-French. I cannot change the keyboard layout from the GUI/Desktop see pic.
I have the feeling I need to install new layouts, perhaps using apt-get something! (noob)
SO the questions could be how to add new layouts? (I have root btw)
I'm trying to install the repo command so I can compile CyanogenMod for my phone but whenever i enter the command:

Can anybody help me out here?
