There is nothing important on your list to select. The important sources are on the "Ubuntu Software" tab. Most folks want the "Updates" and "Security" boxes. The others are optional. "Source Code" is for folks who want to modify and recompile the software. If you don't know what that means, then you don't need to ...

For anyone encountering this problem - I managed to fix it, although I don't know what has finally fixed it. I've removed again ~/.config/pulse and then reboot. Didn't work. So I removed pulse directory again and then change name of "old_pulse" back into "pulse" (I've done this before). And then rebooted - and it works now. But I don't ...

Reinstall the programs, but remove corresponding files in /etc/apt/sources.list.d/. In case of Brave, see if there is any corresponding file with the command ls /etc/apt/sources.list.d/brave-browser-*.list before, remove it sudo rm /etc/apt/sources.list.d/brave-browser-*.list

Long story short, after some research and examining the logs I decided to take a shot at reinstalling a few things. To that end I tried the following: sudo apt-get install --reinstall dbus python-dbus python3-dbus Fortunately this seemed to clear up the problem.

It did for me (on Chromium), but only because since Ubuntu 19.10, Chromium comes as a snap instead of a deb, meaning the location of cookies, history, user sign-ins, extensions, etc. is now at ~/snap/chromium/common/chromium/Default instead of ~/.config/chromium/Default. Copying that folder over makes all things I listed appear again in Chromium.

Some parts of Firefox seem to fail when it gets upgraded by apt while an instance is running. This includes things such as opening a local file or accessing certain media content types, from my personal experience. Probably all things for which it would load some external libraries that it didn't have in memory before, so when it tries this after an update, ...

I have had Firefox automatically update for me all the time in the past. But, this can be disabled. The version of Firefox that is in the Ubuntu repositories no longer has the checkbox under the General tab of Preferences to enable or disable the automatic updates. However, if you go to your address bar and type in about:config and bring it up you can set ...

I had a similar problem when upgrading from 18.04 to 20.04, although it only affected the headphones and not the laptop speakers. I also experienced problems in controlling the volume. The root cause of the problem was in the default software settings not being ok for the specific hardware (intel card on asus laptop) while for 18.04 it had worked out of the ...

You can use Update Manager or the shell. Both will offer to update you only to the next LTS of Ubuntu. They won't offer to skip releases. To prepare for a release-upgrade: Return your system to as close to stock condition as possible. If you have added PPAs or non-Ubuntu sources, remove them and uninstall the packages that came from those sources. Upgrade ...

I also find this Thunderbird incompatibility between versions annoying.

Ubuntu 18.04 LTS Bionic Beaver is not an old-releases. It is supported release. So you have to replace the repo-lines by archive back. Doing this programmatically is possible by executing: sudo sed -i "s|old-releases.ubuntu.com/ubuntu bionic|archive.ubuntu.com/ubuntu bionic|g" /etc/apt/sources.list And then run sudo apt-get update as usual.

I can think of 2 versions: you can write a script that interogates the right url on https://packages.ubuntu.com/ (like: https://packages.ubuntu.com/focal/mousepad) and grabs from there the info. This could be written pretty easy in python. you can write a (bash)script that checks directly in apt if the package updated. Like: apt show package-name | grep ...

Update Notifier already checks daily. It's an apt systemd timer. It runs at a different random time each day. In this example, you can see that apt-daily (which runs sudo apt update) ran 4:24 ago, and will run again in 1:37. $ systemctl list-timers apt-daily.timer NEXT LEFT LAST PASSED UNIT ...

The simplest solution is this: Go to "Software & Sources/Updates" application. In the other software tab, you should see your erring PPA, which is https://packages.sury.org/php bionic Release Remove the said entry from the sources. Try the update again. This should solve the problem.

Gnome-Disks If you have trouble installing mkusb, (also my choice for installer), you can use Gnome-Disks.

Open Disks, select the USB you want to install the ISO on, click the 3 lines ...

I suggest that you download UbuntuStudio 20.04.1 LTS (or some other flavour of 20.04.1 LTS). Then you can use dd, but it is not 'idiotproof'. Even several linux gurus have destroyed data using dd. So if you want to use it, check and double-check that you will be writing to the correct target drive, the USB pendrive. A safer alternative is to use mkusb. ...

So I fixed it. In short, the key parts were Identify the failing pre-remove and insert exit 0 to skip it. Reinstall all libappstream packages.
