A few years ago I switched from Linux Mint to Debian and noticed that there seem to be two perhaps competing 'software and update' programs in the gui. The one looks like this:
I tend to use the first one over the second one but have always wondered why there are more than one. Maybe I installed one of them at one point but no longer know which one is better or if there is a difference.
In particular, how can you 'tame' the first one. Lets say I want to install just the 'Betriebsysstemaktualisierungen' / operating system updates but avoid the Thunderbird update to 78.7.0 Is there a way to take control of that program so it does not force updates on you which you don't want? How can you tell it to leave you alone about updates to say, Thunderbird?
In the past I suffered due to a forced update from thunderbird 68 to 78 and feel that one of the main benefits of linux and open source over Windows is that you can control the machine more rather than it being controlled from elsewhere with forced updates.
