Hi Bagus, thank you for your report and your help to make Ubuntu better. >From your log what puzzles me most is the error: update-alternatives: error: alternative path /etc/mysql/my.cnf.fallback doesn't exist
This file is part of mysql-common and usually around. I wonder what do the following commands report you: $ update-alternatives --display my.cnf $ dpkg --verify mysql-common $ dpkg --verify mysql-server-5.7 I don't think it really applies as no deleted conffiles are listed, but if you want to reinstall the packages in a way that they would re-populate any accidentially deleted config files you could try: $ apt-get install --reinstall -o Dpkg::Options::="--force-confmiss" mysql-common mysql-server-5.7 Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete for now until you provide the requested extra information. If the suggested workarounds/checks already uncover the issue please still report back so others can find the solution here. ** 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/1685644 Title: package mysql-common 5.7.17-0ubuntu0.16.04.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1685644/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
