[Bug 1766529] [NEW] When resolving changed conf file conflicts, dpkg ignores choice to view diffs

[Bogdan Harjoc]

Public bug reported:

I installed some updates using the "updates are available" GUI and when
updating rsyslog, a GUI prompt for resolving a changed
/etc/rsyslog.d/50-default.conf appeared, and I picked "view diff between
versions", however the update process continued, saving the dist one as
/etc/rsyslog.d/50-default.conf.ucf-dist and leaving the existing one
unchanged.

I guess the "view diff" was the expected behavior here.
