ostree fails with: bwrap: open /proc/192/ns/ns failed: No such file or directory

[flaper87]

I'm trying to create a live-iso using livemedia-creator. This project runs anaconda in the background, which then calls ostree

https://github.com/rhinstaller/anaconda/blob/f0df778cc43e2494fdd0fad131aa8643590510ac/pyanaconda/modules/payloads/payload/rpm_ostree/installation.py#L511-L521

I captured the logs from ostree and this is what I got:

This is probably fallout from edb4f38

I think we should stop doing that on the initial deployment, it's both unnecessary and likely to provoke bugs from trying to use potentially nested containerization in outer arbitrary setups.

What's interesting is that this doesn't happen while running ostree directly on the shell. It happens when it runs under anaconda, as part of the livemedia-creator tool.

Could this be related to the use of mock/chroot?

Yeah almost certainly.

Just wanted to provide feedback. I tested the latest build and it does solve the issue I was hitting. Thanks a lot for the support

[cgwalters]

Awesome, thanks for testing!
