AppImage does not open on Debian Stretch. Sandbox error

[JPL1]

Seems to be some issue with chromium sandbox.

user@user1:~$ chmod a+x Standard-Notes-3.3.3.AppImage user@user1:~$ ./Standard-Notes-3.3.3.AppImage [4024:0229/124157.699079:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_StandaRzoZh2/chrome-sandbox is owned by root and has mode 4755. Trace/breakpoint trap
This seems to be a Debian issue rather than something StandardNotes-specific, but it did not happen with the previous version I was using (3.0.5 I think).

You can get around it by starting SN with the --no-sandbox flag

EDIT - just noticed this is a dupe of #394 . Closing
