Hey @arthepsy , I just wanted to see if you had a license formally authorizing use and such. It's a great PoC, thanks for putting this together!

I think it's an error related to environmental variables, how can I solve it?
If it is not an environmental variable problem, I would appreciate it if you could tell me the cause and solution

Hello, pkexec doesn't launch the pwnkit, has anyone encountered this problem ?

It seems that pkexec does not take into account the environment (the env variable in the program ):
