Had trouble with my original update manager, so uninstalled it here so I could re-install it. The re-install attempt returned a list of errors of files it couldn't access. (no longer supported?)
I had always to struggle with it because this application got stuck during "Calculating...", but now with Linux Mint 18.2 it works really fine. It needs 10 Minutes for calculation when I back up the whole "/" (of course without /media/backupdrive), but then it does it job, even without root privileges!
this app won't update anything until update itself, therefore "refresh button" don't do anything, and that is REALLY CONFUSING, you should make this clear by an warning or something, so ppl won't press refresh and cosider that this app IS NOT WORKING !!!!!
Just recently it has stopped appearing on my panel when closed. I have no idea what caused this but it's very annoying.
would very much like to see a setting where I can set the time when it checks for updates..
