Thank you for your report. This looks like a local configuration problem, rather than a bug in Ubuntu.
Specifically, you appear to have added a third party apt repository and installed a third party package from there (mysql-common 1:10.3.29+maria~xenial [origin: MariaDB]) which is the cause of your failure. You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community Since we use this bug tracker to track bugs in Ubuntu, rather than configuration problems, I'm marking this bug as Invalid. This helps us to focus on fixing bugs in Ubuntu. If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New. ** Changed in: mysql-8.0 (Ubuntu) Status: New => Invalid ** Summary changed: - package mysql-server-8.0 8.0.25-0ubuntu0.20.04.1 failed to install/upgrade: installed mysql-server-8.0 package post-installation script subprocess returned error exit status 127 + MySQL postinst failed because of third party mysql-common package -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931034 Title: MySQL postinst failed because of third party mysql-common package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1931034/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
