Hi Hiren, >From the logs, it looks like it can't find the database files:
Specified filename /var/lib/mysql/ibdata1 does not exist. Checking if update is needed. Checking server version. Error occurred: Query against mysql.user table failed when checking the mysql.session. Have you put the db files in a custom location? There are other tables that it can't find as well: 2018-12-17T05:07:44.711665Z 0 [ERROR] Can't open and lock privilege tables: Table 'mysql.servers' doesn't exist 2018-12-17T05:07:44.711767Z 0 [ERROR] Native table 'performance_schema'.'cond_instances' has the wrong structure 2018-12-17T05:07:44.711799Z 0 [ERROR] Native table 'performance_schema'.'events_waits_current' has the wrong structure 2018-12-17T05:07:44.711829Z 0 [ERROR] Native table 'performance_schema'.'events_waits_history' has the wrong structure 2018-12-17T05:07:44.711861Z 0 [ERROR] Native table 'performance_schema'.'events_waits_history_long' has the wrong structure 2018-12-17T05:07:44.711897Z 0 [ERROR] Native table 'performance_schema'.'events_waits_summary_by_host_by_event_name' has the wrong structure Please check your configuration and database files to make sure they're as mysql expects them to be. If this still looks like a bug rather than a configuration issue, please give more info and change the status back to "new". ** Changed in: mysql-5.7 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808744 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/1808744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
