[...] you need to remove the PPA from the software list.
Hi!
Removing the PPA, is unnecessary.
All we need to do, is UNCKECK the PPA line using Synaptic Package Manager, in the "Other Software" tab.
From time to time though, you will need to check if the appropriate version became available.
To do so, go again to "Other Software", check the PPA line and see if after reloading the software list, any error occures. If it does, uncheck again the line. It means that the appropriate version is still missing.
I hope this will help people that have some more apps provided through PPAs.
Best regards!
