I’m new to Whonix and Linux in general. I am using Whonix in Virtual Box (Non-Qube).
I tried to run MAT2 (Metadata Anonymisation Toolkit v2).
When running mat2 with flag “s” for a file.PNG (8KiB) it says: bwrap: setting up uid map: No such file or directory
After this message, the process is running for several minutes but nothing is happening. I then cancelled it.
Is this normal behavior, the process just takes that much time and I would just have needed to wait some more minutes to finish the run successfully?
Or is there something going wrong with bwrap? I already found the instructions on this page:

Seems there were some problems with bubblewrapper, but I am not quite sure if that’s a related problem. Also the mentioned solution “–no-sandbox” does not work for me. It says, this flag does not exist.
Can someone help me how to proceed to to get MAT2 running on Whonix?
Thanks for this information. Regarding the second option: How does this work?
According to the bwrap manual page, the --no-sandbox flag does not exist for bwrap. Furthermore when starting mat2, how can I hand over this flag to bwrap?
Guess this is some basic linux understanding issue, but anyway I’d be thankful for any hint or a link to further guidance.
I can confirm that after uninstalling bubblewrap I was able to run mat2.
But unfortunately Tor browser was not running anymore after rebooting the system. Installing bubblewrap again did not fix the issue.
Can’t tell a 100% this error happened due to uninstalling bubblewrap, since I also updated Whonix after the reboot.
If you are interested in the error message for maintenance purpose, I can look it up and add it later on.
I can confirm that mat2 still doesn’t work on Whonix. I use recent version of Whonix-Workstation updated via upgrade-nonroot. The same error bwrap: setting up uid map: No such file or directory. Are you going to fix it? I don’t want to decrease privacy through bwrap removing
I’ve found out that mat2 version preinstalled in Whonix-Workstation is 0.8.0 from buster repository and it doesn’t have --no-sandbox flag. I upgraded mat2 to version 0.10.0 from buster-backports repository which has --no-sandbox option but it still doesn’t work. Returns the same error:
bwrap: setting up uid map: No such file or directory
