Yes we need to update the packaging to optionally allow libfuse3-4.

Come to think of it, although that should be helpful for building from source, I'm not actually sure it will be sufficient for running an older binary on the newer...

That's interesting, but I presume rebuilding it on sid won't help because I don't see how a single compiled package can work with either of two libraries. The only thing...

I have done some more research since the meeting. The backports repository is not relevant to this situation because it's for making newer packages available in older distributions, and what...

Thank you for the detailed analysis and report! I was able to easily reproduce the issue on el8. That configuration option is [documented](https://apptainer.org/docs/admin/1.4/configfiles.html#setuid-and-capabilities) to only be relevant to the root...

It's not EL8 itself, because on two different EL8 clusters that I regularly use I get different results without subuid. One succeeds and one set_attributes errors. I have been trying...

The difference is the way that things were set up when I **built** the first sif file (ubuntu.sif). If that original image is built with subuid as opposed to fakeroot,...

Since none of the regular maintainers of Apptainer have access to that device, you're going to have to do the debugging. Does that missing file`/opt/amdgpu/share/libdrm/amdgpu.ids` exist on the host? Maybe...

Ok, it's good to know that fix. Please proceed to find out the cause of the segmentation fault. At this point it isn't clear whether or not it is an...
