>From your log: /var/lib/dpkg/info/mysql-server-5.7.postinst: line 56: mysqld: command not found
Now having mysql-server-5.7 installed that should not happen ever. root@x:~# dpkg -S /usr/sbin/mysqld mysql-server-core-5.7: /usr/sbin/mysqld We can see that this binary is from the package mysql-server-core-5.7 And mysql-server-5.7 depends on it: apt-cache show mysql-server-5.7 | grep Dep |grep core ... mysql-server-core-5.7 (= 5.7.11-0ubuntu6) Due to that there must be a configuration change e.g. a manually forced package or file removal that has dropped the file - this is a broken local config change which can not be fixed by the package. You can check the packages if they are correctly installed and e.g. reinstall them if required (apt install --reinstall ...) dpkg --verify mysql-server-5.7 mysql-server-core-5.7 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834405 Title: package mysql-server-5.7 5.7.26-0ubuntu0.16.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1834405/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
