From your logs I see: Failed to preset unit: File mysql.service: Link has been severed
and 2022-02-26T15:56:06.044551Z 1 [ERROR] [MY-012530] [InnoDB] Unknown redo log format (103). Please follow the instructions at http://dev.mysql.com/doc/refman/8.0/en/ upgrading-downgrading.html. From the log I think I see some tries to install mysql with some back and forth to mariadb and such. As you have found out already mysql and maridb are incompatible to each other and I wonder if what you face and report now is just a config that you have reached now due to this conflict. I beg your pardon but let me ask, did you face other initial issues when installing/removing mysql? Or did you just try mysql and maridb (working at first), but since hat try it does not work anymore? I can make a few assumptions and propose suggestions for you to try: - I see you have not yet removed/purged mariadb yet, as long as that didn't happen mysql won't install fine - based on that redo log error I'd assume that mariadb left such a file and breaks mysql - if you happen to use mysql from other sources than the ubuntu archive that would also conflict with those => removing those files might be a good step to unblock this I hope that these ints will help to resolve your local setup issues, right now it isn't clear enough to spot an issue in the Ubuntu package to fix. So I'll mark incomplete and would ask you to speak up if your further debugging identifies such an issue in the package. ** Summary changed: - package mysql-server-8.0 8.0.28-0ubuntu0.20.04.3 failed to install/upgrade: o subprocesso instalado, do pacote mysql-server-8.0, o script post-installation retornou erro do status de saída 1 + mysql install fails - Unknown redo log format (103) ** Changed in: mysql-8.0 (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/1962369 Title: mysql install fails - Unknown redo log format (103) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1962369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
