Was on Ubuntu 22.04, backintime 1.3.1 was working. Installed Tumbleweed from YaST software and it began throwing rsync errors as myself and the other reporter on the github issue reported (repasted below) when attempting to backup or restore configuration over ssh. Local backup option works fine without any errors.
Spun up an Ubuntu VM and a Tumbleweed VM to test. Experienced the same issues with the 1.3.1 version installed via YaST, as well as the previous 1.3.0 release and current 1.3.2 release when compiled and installed. On Ubuntu I was able to perform a configuration restore and a backup over ssh with an Opensuse guest and physical box, and over ssh to itself. On Opensuse I was unable to due to the rsync errors connecting to another Opensuse machine, the Ubuntu machine, or to itself over ssh.
I used grsync and rsync from command line (including the options backintime complained about) to verify rsync was working, and it did work.
I typically would only try for help via the application channels, but it appears the issue is only with Opensuse.
I there anything else I can check here to see where the problem is?
