Assembly3 py-slvs failed [Errno 13]

[sleepyspecter]

I'm having an issue installing py-slvs on the RealThunder branch that I haven't found anywhere else. It's the edge release snap for Pop!_OS; updated 13 December 2022. I'm not sure if not being able to access /etc/os-release is the real issue, or if something else is going on, but I've tried every solution I could find so far to no avail.

Let me know if there's any other info I should provide. Any help is greatly appreciated.

you might get a faster response if you create an issue on realthunder's github repo

That makes sense. I wasn't quite sure about the relationship between FreeCAD and the RealThunder branch. I'll take my question there. Sorry, for the unnecessary post.

Apologies for replying to an old thread, but it came up on Google when searching for the same problem of installing py_slvs using a Snap installation on Pop!_OS. My workaround was to install the snap in dev mode.

Code: Select all

sudo snap install freecad-realthunder --devmode --channel=latest/edge

Note that this bypasses the inherent security built in to snap by giving it access to the whole filesystem, but I'm okay with that as I trust the FreeCAD application.

Replace the channel value with

Code: Select all

latest/beta

to get the latest "tip" releases.

I found this bug: https://bugs.launchpad.net/snapd/+bug/1881189 I hope in the future they solve it, in the meantime devmode work around will get it done with the security caviat
