Package: policykit-1 Version: 0.105-21 Severity: important Tags: a11y Hello,
As reported also on https://bugs.launchpad.net/ubuntu/+source/policykit-1/+bug/1782320 , on upgrading from policykit 0.105-20 to 0.105-21, brlapi connections have stopped working. The idea is that the brltty daemon checks whether programs trying to connect to it through brlapi are legitimate by having an active session. This used to work previously, but not in 0.105-21 any more. Notably, we get this GError: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: process with PID 12570 has been replaced which seems to be due to a mismatch in program start time (which does not make sense, the start time hasn't changed). This is due to the introduction of Fix-CVE-2018-1116-Trusting-client-supplied-UID.patch , disabling it fixes the issue. This is really problematic, because it completely break braille output in graphical session, thus making the system very useless for a lot of people, unless changing the configuration by hand to revert to keypass-based authentication in /etc/brlapi.key.
