Thanks for filing this bug in Ubuntu. This is the error that was logged:
ERROR: Unable to start MySQL server: mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory) Tthe missing directory /etc/mysql/conf.d/ is part of mysql-common: https://packages.ubuntu.com/bionic/all/mysql-common/filelist If you don't have that installed, then maybe you purged packages that you shouldn't (like mysql-common), or ran rm -rf in some mysql directory in /etc. It's not clear. I suggest you start from a clean state, as I cannot reproduce that problem with a fresh bionic container. ** Changed in: mysql-5.7 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1803697 Title: package mysql-server-5.7 5.7.24-0ubuntu0.18.04.1 failed to install/upgrade: installed mysql-server-5.7 package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1803697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
