Uninstall and fresh reinstall

[lilmissndemon]

Ok can some one guide me on how to completely remove zm mysql etc so that i can try a fresh try at this? i have ubuntu server 16.04 (only used for a plex server) and im trying to run two webcams in zoneminder from that server ...ive tried so many different approaches to this that it seems best way is to just try again with a fresh install of zm but i dont want to reinstall ubuntu cuz its set up for plex as mentioned before...also the webcams are seen as connected theyre just not viewable without gui on that server...any help u can provide is much appreciated

If you are getting unmet dependencies for MySQL it is likely you did not set up LAMP correctly. Removing Zoneminder should not remove anything still needed by another installed application or program.

Run this to try to fix things:

sudo apt-get -f install

ok when i tried that apt-get -f install it returned this error
