Suggestions are great things. I decided to install and test this app.
It needs to be installed with PiP, I could find no other way of doing so.
Installed PiP and installed Bauh.
Launched it and entered my password. Then it said "Synchronizing: 1.0%" and...
it stuck there.
After 5 minutes, I closed it.
Launch - try again.
It did it again.
Third time was the charm. This time it synced right away.
I went to Settings to configure it. Under the Types tab, Appimages cannot be selected and it is grayed out.
There are question marks next to certain settings - the intention is to click on them for more information.
Every question mark I clicked on yielded nothing. Nothing happened.
I found the solution to all of the above problems.
In terminal, I ran
bauh --reset
sudo pip3 uninstall bauh
EDIT: I must point out that I still prefer @Maxwell-J 's suggestion over my own and am editing the linked Tutorial to include it.
