I am running urbackup on a Debian server since a few years.
Debian is 11.2, with all updates.
Two weeks ago, the urbackup-server package was upgraded from 2.4.13 to 2.4.14, together with libcrypto++8
Since then, urbackup does not start any more (seg fault).
All logs are empty.
My question is to know if the problem is in urbackup or in lybcrypto?
Regards, Jacques-D.
