I am monitoring the upstream issue since last week. I would like to work on a fix for this on NixOS as soon as the fixes for other distros are released as announced in the linked upstream issue.

This issue is really annoying as we rely on enterprise vpn with sso at Nesto which is not supported by openvpn2.

Is there any workaround right now?

[KFearsoff]

Oh. Uhh. Sorry, I haven't noticed this issue in time, and nobody pinged me.

I'm currently working on a fix, which will probably just be a boring glib pinning.

[KFearsoff]

So, I have spent time working on this, and I unfortunately couldn't figure out the intricacies of the build process of glib in Nixpkgs. No matter how much I tried, I just wasn't able to make openvpn3 actually depend on the old glib: for some reason it always prefers the newer one, even if its dependencies use the old one correctly.

There is work in the pipe to fix the glib2 related issues .... See this comment for more details: https://github.com/OpenVPN/openvpn3-linux/issues/171#issuecomment-1858487477

The instructions in that comment is to be used on top of an existing installed version; for the time being it only replaces the first binaries failing with glib2-2.76 - but everything will be migrated to the new D-Bus implementation layer (GDBus++) - when that milestone is reached, the v22_dev release will happen.

@KFearsoff hi! Just pinging you to let you know that v22_dev is released.

[JarvisCraft]

Hi there! Has anyone managed to change pkgs/tools/networking/openvpn3/default.nix for the upstream v22_dev which uses Meson now?

[JarvisCraft]

For those looking for the fix: I've created a PR where I update the system to v22_dev. I've just managed to make it work, but there still are some chores and clean ups I would like to do before creating a PR. E.g., I currently used a forked branch of openvpn3 instead of patches and I haven't made the module to write openvpn3 configs yet, but you already can play with it: https://github.com/JarvisCraft/nixpkgs/pull/1

[JarvisCraft]

There we go, I've created #326623 in which the version is updated to v22_dev.
