I get an error running apport-collect. I am beginning to think that the last update to this system went wrong. There are other problems comming up which I did not have before. I have now tried the display with another 22.04 install and that works OK. So I think this problem report should be closed. bob1@Juptier:~$ apport-collect 1975557 ERROR: connecting to Launchpad failed: Unable to find the server at launchpad.net You can reset the credentials by removing the file "/home/bob1/.cache/apport/launchpad.credentials" bob1@Juptier:~$ > The difference between 21.10 and 22.04 might just be that we now default > to Wayland instead of Xorg.
