    dpkg dependency problems not removing

    When removing a package, I got the following error message

    root@82-165-118-245:/~# dpkg --remove psa-phpmyadmin
dpkg: dependency problems prevent removal of psa-phpmyadmin:
 plesk-core depends on psa-phpmyadmin (>= 5.1.1); however:
  Package psa-phpmyadmin is to be removed.

dpkg: error processing package psa-phpmyadmin (--remove):
 dependency problems - not removing
Errors were encountered while processing:
 psa-phpmyadmin
root@82-165-118-245:/~#

    It is fixed by specifying –ignore-depends=plesk-core in apt command.

    Example

    root@82-165-118-245:/~# dpkg --remove --ignore-depends=plesk-core psa-phpmyadmin

    On a Plesk server, MySQL somehow went missing. When I tried to remove a package, I get error

    root@82-165-118-245:~# dpkg --remove plesk-config-troubleshooter

Check the error reason (see log file: /var/log/plesk/install/plesk_18.0.39_installation.log), fix and try again

    To fix this, I removed the prerm and postrm scripts. These scripts execute before and after a package is removed. It is not recommended to remove it, but if these scripts prevent you from uninstalling a package, you can remove them as the last option.

    mv /var/lib/dpkg/info/plesk-config-troubleshooter.prerm ~/
mv /var/lib/dpkg/info/plesk-config-troubleshooter.postrm ~/

    Or you can just edit the file, put

    exit 0

    somewhere before the error happens.

    When installing software on Ubuntu, i get following error.

    To fix this, run

dpkg --configure -a
apt update

    Replace PACKAGE_NAME_HERE with actual package that fail. In this cause spl-dkms.
