I already identified the problem was somewhat related to python, So I removed the module distro info manually using the command python3 -m pip uninstall distro-info And, I reinstalled the same as follows sudo apt install --reinstall python3-distro-info That is it. do-release-upgrade It is fixed and works like a charm.

The problem is the used ca: $ python3 -c 'import ssl; print(ssl.get_default_verify_paths().openssl_cafile)' /usr/lib/ssl/cert.pem But: $ ll /usr/lib/ssl/cert.pem ls: cannot access '/usr/lib/ssl/cert.pem': No such file or directory You can fix it by linking the global ca-certificates to the file Python uses: ln -s /etc/ssl/certs/ca-certificates.crt /usr/lib/...

Just hit the same symptoms - stuck on grub-pc config. There were a small number of dpkg processes which seemed to be stuck. I terminated the software update session on the desktop by dismissing the parent terminal, but did not kill the dpkg processes. I checked the syslog output, and noticed a USB device seemed to be reporting some sort of communication ...

You will avoid a lot of problems if you let your Ubuntu system's built-in tools keep your Ubuntu system up to date. For cases like yours, where that simply isn't possible, best practice is to keep your custom/project environment in a Virtual Machine or a Container. That way, your customizations don't cause conflicts and other problems on your base system. To ...

Assuming you have php-fpm installed, it is started/enabled with systemctl, and it is running properly/configured to use a socket, you should find a .sock file in /var/run/php/ . ls -lsha /var/run/php NGINX connects to PHP, according to your configuration, via /var/run/php/php7.2-fpm.sock . fastcgi_pass unix:/var/run/php/php7.2-fpm.sock; I am assuming that ...

My hint seems to help for dual screen modes and is only an addendum to Erics recommendation: My second screen was set to 1600x1200. I switched to 1280x1024. Now I can scroll through the applications now. No news to what Eric mentioned. Now what seems to be interesting: ANY vertical resolution on the second screen, which is below 1200 works. Now comes the ...

So, I looked at the DeVeDeNG debugger and it looked like it was expecting an mp2 codec. I went into Openshot export DVD settings and changed the Audio Codec from aac to mp2. Then I exported the project and ran DeVeDeNG on the .dvd file. After an error message (not the same - I don't think it was related) first time round, I tried again and the job completed ...

None of PPA are really "necessary". You can install additional software from there at your own risk. When you upgrade a release all PPA's are disabled by an upgrade script. You can safely remove all PPA's at any time. If you really need software from these PPA and are sure that they support 20.10, you can change focal to groovy by pressing the &...

Turns out my GTK theme was broken, simply switching to any other theme did the trick. Specifically on an LXLE installation, I ran lxappearance and chose another theme. For other distros, simply go to ~/.config/gtk-3.0/settings.ini and edit gtk-theme-name.

Logging in on X11 instead of Wayland solves the issue. Most probably the following issues in snapd/Ubuntu are related https://github.com/snapcore/snapd/pull/9530 https://forum.snapcraft.io/t/apps-wont-run-and-crash-on-gnome-wayland/20322/14 https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1897224 (see related issue in Space tracker for details)

Thanks for your hints. I first intended a reboot through the UI. The request was accepted, the screen went blank, but nothing else happened after that. You could see small disk activity for about 30min. I then used SSH from a Win laptop to login in the Ubuntu system, entered sudo pkill dpkg followed by sudo dpkg --configure -a. After these, the Ubuntu 20.04 ...

User jos from the comment section is right. If you have the groovy repos in your /etc/apt/sources.list and do sudo apt update sudo apt dist-upgrade you have technically an up-to-date Ubuntu 20.10 installation, regardless of what the text file says in /etc/lsb-release. I don't know how you ended up with wrong lsb-release info. I would recommend you to ...

I have a dual boot system with Ubuntu 20.04 and 18.04. I wanted to upgrade the kernel of 18.04 (server) Used this command: sudo apt install linux-generic-hwe-18.04 But it would not update. The problem for me was that the grubloader loading at start-up is configured in Ubuntu 20 and is on another partition. So I had to boot into Ubuntu 20 and run this command ...

Update + Solution As suggested by pLumo in the comments my /etc/apt/sources.list was quite messed up: it was still using the old version for Ubuntu 18.04 (2:4.7.6). Therefore I have followed these instructions to regenerate a new sources.list (which for Ubuntu 20.04 can be found here).

Solution sudo apt upgrade did not show anything, but sudo apt update did show a package that was kept back. It was qtcam because the repo was stuck on xenial, I updated the repo to use bionic and I updated packages normally. After that the upgrade UI was still not working but using sudo do-release-upgrade did work and I could upgrade to Ubuntu 20.10 normally....

No, it will not work, because subsequent Ubuntu versions DO NOT support 32-bit architecture. It just doesn't have the code/libraries/setup to run them. You would have to switch to another distribution that supports 32-bit systems and can apply the steps above to do so if you wish to continue using your machine on a GNU/Linux OS. I personally would recommend ...

Move your home directory to a different partition. Make a list of all your installed software. Shrink your root partition. 32GB is usually enough; 64GB should be plenty.

You seem to be running a 32-bit version of Ubuntu, as evidenced by: There will not be any further Ubuntu releases for this system's 'i386' architecture. That's correct. 32-bit desktops have been dropped from future releases, including 20.04. There were simply too few 32-bit desktop contributors and testers. Your current 32-bit Ubuntu 18.04 will be ...

It turns out that it was the mesa gl library that didn't get updated with 18.04 LTS.

That's because you can put that address in your browser to see that the source files do not exist on the internet, so it's not being maintained any more. I have done a search for those files, and they seem to still exist at these locations, so you can try to replace the URLs in /etc/apt/sources.list with one of them: http://18.219.209.11/ubuntu-ports/dists/...
