I suddenly noticed after trying to open a .zip file yesterday that the archive manager has been removed somehow. As far as I know, and I'm absolutely sure, that I didn't do anything that might cause it to be removed.
I checked and double checked. I even ran the apt-cache policy command, but no, there's no engrampa, no archive manager...
So what's going on here? Malware or something?
Or was it moved in the update process?
I know I can just install it again, but just wanted to put it out there...
If you can’t find it at all in the repos, check that they’re still enabled. Run Software & Updates in the Control Center and tell me what is enabled in the first, second and third tabs. Also confirm that the Proposed repo in the sixth tab is not enabled and has never been.
Did you also reinstall ubuntu-mate-desktop and it went without issues? If so, you should be fine.
You repos are ok (apart from the fact that you have twice the disabled src repo for Persepolis; you can remove one), I've checked the content of your PPAs and nothing suspicious there. I haven't checked the MS repo but I doubt it hosts packages that would conflict with the MATE desktop.
Is it normal that you're using the Bangladesh server for Ubuntu (I mean, is it the closest to you)?
I didn't install ubuntu-mate-desktop, is it really necessary/required? I mean I only had one app missing...
It's to be sure that there weren't other apps removed. Besides, if Engrampa has been removed, it's quite probable that the desktop metapackages has been too and this could lead to issues when upgrading to the next version. So, better check.
It’s not a friendly output but the idea is to find the line(s) and file(s) involving engrampa. Then, opening the appropriate log file will show all that was going on when engrampa was affected.
Perhaps someone else has some better tools to dig into apt history - I use synaptic for everything because it keeps a very nice history.

I remember removing the other apps, but where did Engrampa come from!!
There’s only one other occurrence of Engrampa in this file, and that’s when I installed it again yesterday…
OK, engrampa depends on p7zip-full. I looked this up, it’s not in your output. When you entered the apt-get command to remove p7zip-full the response should have mentioned engrampa has to also be removed. When you said “Y” away it went.
So by reinstalling engrampa I’m sure you’ll find it also installed p7zip-full again.
Like I mentioned. I use synaptic for everything. It’s so easy to miss these messages on the commandline - synaptic makes it pretty clear what it’s doing.
EDIT: Just to see what I mean, you might try to uninstall p7zip-full again and see what it says. Then, say “N”.
