In the "Software & Updates" application, when I check/uncheck any sources or ppa and click "close", I get this (which is normal):

After clicking "Reload", I have these errors:

It seems like the problems with proxy. I do use proxy, but even when I disable it in "Settings", the problem remains. However, I don't have any problem with sudo apt update.

I don't have any proxy-related env variables, nor proxies for apt. I don't know why it keeps reporting proxy issues.

Edit 1: The output of sudo apt update:

    Please run sudo apt-get update and paste its full output to question body. If long - use pastebin and share a link. – N0rbert Sep 20 '21 at 20:39
  • @trondhansen Synaptic is just a front-end and no, you shouldn't run a "partial update". We need to see the full error messages as requested by N0rbert. – ChanganAuto Sep 20 '21 at 22:52

Try sudo ldconfig /usr/bin/gpg. See: https://unix.stackexchange.com/a/677711/114401

It worked for me. sudo apt update now works again.

I had the same problem. I ended up dis-selecting the repos (that were showing an error in the apt-get update message) from the in the "other sofware" section of updater's settings.

I also selected the "best server" in the "download more" menu of the "ubuntu software" section of "software updater's settings".

P.S. I also updated from LTS to non-LTS but I doubt that had anything to do with it.

after this I no longer get the annoying error message (Which is frankly very hard to close if the cancel button is hidden).
