>From your log I see: Setting up mysql-server-5.7 (5.7.23-0ubuntu0.18.04.1) ... locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory Error occurred: Cannot select database. mysql_upgrade failed with exit status 1
And in the mysql error log related to that: 2018-08-06T18:45:33.244519Z 0 [ERROR] Can't open and lock privilege tables: Table 'mysql.servers' doesn't exist I've seen a few cases were this was related to overlayfs [1], but most others like [2] are certain variations on deleted or permission-changed DB files. It seems to me that the DB config was modified breaking the service start, that in turn will break the package upgrade/install.
