Hi, thanx for your answer. However, I am a Linux newbie, and have not tinkered with my system. It is basically a fresh 20.04 and I have applied all updates. I have definitely not done anything with "mydomain". So why is that I get this error, do you know? How can I resolve this problem? Should I set the "mydomain" thing to something? Why is it that a fresh Ubuntu 20.04 with all updates triggers this error?
Right now, my Nvidia driver has reverted back to Noveau driver, because the latest update could not update the Nvidia driver - I suspect the update error is because of this "mydomain" problem? So now I am stuck at 800x600 resolution which is unusable. I can not work. I remember earlier when I used 18.04 LTS, I also got problems like this. After a update the resolution was stuck to 640x480. I tried to fix it by installing Nvidia driver, but no luck. At the end I bricked my Ubuntu install, when I tried to download the Nvidia driver and install it manually. So I had to revert back to Unix. Now I am trying to transition to Ubuntu, but I get this problem. I am stuck at 800x600 with Noveau and cannot install Nivida driver to fix the resolution. I dont understand why the updates cause these problems? Should I set the "mydomain" to something? Do you have any clue where I can start to dig? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895156 Title: package postfix 3.4.13-0ubuntu1 failed to install/upgrade: installed postfix package post-installation script subprocess returned error exit status 75 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1895156/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
