Failed to map shared segment

[jander049]

When I try to launch the appimage I get the following error:
/tmp/.org.chromium.Chromium.z5bAif: failed to map segment from shared object

To Reproduce
This started happening this morning and now I see the error every time I try to start from the command line. When I click on the AppImage itself to launch it just fails silently.

Desktop (please complete the following information):

• OS: Debian Testing
• Desktop Environment, if applicable (on Linux)
• XFCE 4.14

Additional context
I'm not sure but this could be because my /tmp directory is mounted with nosuid,noexec,nosuid permissions but it hasn't been a problem until now.

User namespaces are also disable on my system.

Hi

User namespaces are also disable on my system.
Did you see #1565 ? Can it be it?
I'm also not sure how it should run with noexec

[jander049]

I have to use the no-sandbox option to run it and have been without issue until nown

We have updated Electron few versions ago already and enabled sandbox there.
As far as I understand it worked for you and it's a duplicate of #1565.
You can apply any of the solutions (suid binary, user namespaces or no sandbox).

It doesn't start for me even with the no sandbox option now, it used to up until this morning though. This is the full error I see:

Okay, it's a different problem. Can you try setting TMPDIR as described here balena-io/etcher#1699 or here balena-io-modules/drivelist#209
?

[jander049]

Yes this worked for me

TMPDIR=$XDG_RUNTIME_DIR /path/to/appimage

I wonder if we could fix it on our side somewhere. Judging by the stacktrace it seems like it's inside keytar somewhere.

@jander049 AppImage devs at AppImage/AppImageKit#1021 (comment) asked for an image, maybe you could make one for them
