Hi.

When running firejail I get this output:

$ firejail --debug --profile=~/.config/firejail/freeplane.profile \
  /home/sl/Software/Freeplane/freeplane/freeplane.sh
Creating empty /run/firejail/mnt/dns-etc/zsh directory
Mount-bind /run/firejail/mnt/dns-etc on top of /etc
Error chdir: sandbox.c:1117 sandbox: Permission denied
Error: proc 438162 cannot sync with peer: unexpected EOF
Peer 438163 unexpectedly exited with status 1

The error message is showing no hint at all which chdir failed. Where can I get this information from?

As a first step you should provide necessary details like firejail version and the profile you use. The easiest way is to follow the bug template.

Hi.
I fixed it by myself, thanks for your effort.

Maybe you can make the log/messages a bit more verbose to see which dir is meant?

Thanks.

Thanks.

Good idea; done in commit f24a49a2c ("sandbox.c: print the dir on failed
chdir(cfg.homedir)", 2022-12-09).
