Add/Remove Programs - Kubuntu 18.04
 

Hello all,
I went to
https://foldingathome.org/start-folding/

and downloaded
fahclient_7.6.21_amd64.deb
fahcontrol_7.6.21-1_all.deb

I just downloaded each, and clicked on each and clicked on install.

How do you uninstall apps?
There is Discover and at the bottom right of the Discover window, there is Installed.
But in that list, I don’t see fahclient and fahcontrol.

Does Linux maintain a separate list for things installed from DEB files?

I know that I could do this from the terminal
sudo dpkg -r fahclient
sudo dpkg -r fahcontrol

but I am wondering how Linux has evolved.

"Linux" has nothing to do with packages. Package managers do.

You seem to be using Kubuntu. https://userbase.kde.org/Kubuntu/Advanced/en

So, I'm suppose to use Muon to uninstall it?
The fahclient and fahcontrol are in the list of Muon, so that is looking good.
I select fahclient and click Remove and click Apply Changes and it says could not download Packages.

It seems to be an option.
Screenshot?

Generally, third party software sources such as you linked to, should have a README or similar file which explains how to remove it. It is obviously not part of the Ubuntu/Debian systems or repositories so it is up to the developers to explain.

Here are a couple of screenshots of the Muon package manager.

They are deb packages, so users should use whatever deb frontend they are comfortable with.

And what does it show if you click on "Details >>"?

Evo2.

fahcontrol is shown as Broken, to me this is not looking good. When asked to perform an action (install, remove, upgrade, whatever) APT (and Muon is a frontend to APT) tries to repair broken packages, downloading other packages in the process if needed. Looks like a dependency of fahcontrol is missing from Ubuntu repos.

From the apt-get manual page:

Nothing happens. I think it is not well programmed.

This is a fresh install of Kubuntu 18.04 in VirtualBox. I was testing to see if the FAH stuff is functional (install, run, uninstall).
2 of the 3 DEB files installed. That's what you see in Muon.

I could not install
fahviewer_7.6.21_amd64.deb
It says:
Error: Cannot satisfy dependencies

So, in any case, 2 of the DEB were installable. Why can't they be uninstalled from Muon? I a able to uninstall them from the command line.

Hi,
oops, I should have realised this. I tried to help someone with what was probably the same problem about a year ago

https://github.com/FoldingAtHome/fah...ment-606369427

I was running FAH at the start of last year when they were helping out with COVID-19 research.
