Thank you for taking the time to file a bug report. Checking the logs I noticed the mysqld failed to start:
ERROR: Unable to start MySQL server: /var/lib/dpkg/info/mysql-server-5.7.postinst: línea 102: mysqld: orden no encontrada Please take a look at https://wiki.debian.org/Teams/MySQL/FAQ for tips on fixing common upgrade issues. As you can see this might be an upgrade issue, so please take a look at that wiki page. Moreover, I saw some attempts to run mysql from a nextcloud snap: [ 12.712907] audit: type=1400 audit(1594569471.624:107): apparmor="DENIED" operation="capable" profile="snap.nextcloud.mysql" pid=2856 comm="mysqld" capability=24 capname="sys_resource" This might be also related to your issue. Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I am marking this bug as 'Incomplete'. However, if you believe that this is really a bug in Ubuntu, then we would be grateful if you would provide a more complete description of the problem with steps to reproduce, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to "New". For local configuration issues, you can find assistance here: http://www.ubuntu.com/support/community ** 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/1887293 Title: package mysql-server-5.7 5.7.30-0ubuntu0.18.04.1 failed to install/upgrade: instalado mysql-server-5.7 paquete post-installation guión el subproceso devolvió un error con estado de salida 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1887293/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
