--- Comment #16 from Mattia <mattia.ve...@tiscali.it> --- I confirm all the issues are now fixed. Switching to dummy backend does not make PM crash anymore. About the polkit dialog which wasn't showed, launching PM from console showed a lot of "qca does not support rsa" messages. I've found that by installing package qca-qt5-ossl I can successfully authenticate and see the devices. >From console I can also see the "Inavlid cryptographic signature errors" every time I switch the backend. I will open a new ticket for that, because I've noticed some other strange behaviour here. -- You are receiving this mail because: You are watching all bug changes.
