Lets start by saying i'm made a rather good F up here and tried to install plesk on top of cpanel. I'm not sure why but its done and have a working version of cpanel but with a messed up install in the background. Since this is production i'll rather not wipe it till i've explored my options.

When ever trying to install or remove anything i'm getting this;

root@51-104-209-196:/etc/apt# sudo apt install --fix-broken

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 plesk-core : Depends: plesk-backup-utilities (>= 18.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

As you can see --fix-broken isn't working but if i purge this system of plesk then i stand a chance of repairing the cpanel side of things. I've also tried;

root@51-104-209-196:/etc/apt# apt-get purge plesk-backup-utilities

Any ideas rather than 'wipe and start again'?

Question title and question do not seem to be about the same thing.

Running `sudo dpkg -P cpanel-pigz` will fix this issue.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
