Why pkexec and not sudo?
Hello folks, this is a general question about something that I can't get into my head. And I have less knowledge about that part of a GNU/Linux system. What is the difference of pkexec and sudo? What is the advantage of using pkexec to run BIT as root? Kind Christian

pkexec is part of the PolKit (policy kit) and supports - a finer permission granularity than sudo (which is "all or nothing") - permission escallation by just asking the user via message ("unlock") instead of asking for root/sudo password. In other words: You can grant some administrative rights to an application without giving the user full admin rights. The policy(kit) declaration file of BiT is this one: https://github.com/bit-team/backintime/blob/3a56a4cf5ad6185b7d44d5a65ee1c07a... More details about PolKit can be found here (in German): https://wiki.ubuntuusers.de/PolicyKit/
