Firejail updated from 0.9.64 to 0.9.68 when I ran Yast. Then on trying to run firefox in a firejail sandbox
firejail --private /usr/bin/firefox
I got the “Server not found” message so web pages would not load. I rolled back to 0.9.64 and it works again (some other updates were lost in the rollback). I updated firejail using zypper to 0.9.68 and it is broken again. Is this perhaps a SUSE thing or should I post on firejail site? I note the recent security update on firejail.
Sorry this should be headed “Firejail 0.9.68 won’t work”
I got the answer from the firejail discussion on github.
see https://github.com/netblue30/firejail/issues/4954
The problem is that there needs to be a line in the file /etc/firejail/whitelist-run-common.inc as follows
whitelist /run/netconfig/resolv.conf
This can replace the line whitelist /run/NetworkManager/resolv.conf as Suse is using netconfig.
