If you have trouble with building it, please run yay -Scc or yay -Sc.

FYI. I replaced gdbuspp-git with gdbuspp in the PKGBUILD dependency, and it seems that the build fails because the locally cached PKGBUILD is not updated.

Add automake to the build dependenices.

Can't exec "aclocal": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 274.
autoreconf: error: aclocal failed with exit status: 2

Fuzzy is spot on - the libprotobuf.so issue comes about because other software updates have modified files which openvpn3 depends on.

Rebuilding will cause openvpn3 to use the updated files and the error will go away.

I also recommend installing rebuild-detector - this will warn you when AUR packages have been affected by similar problems so you can be proactive about rebuilding (and avoid similar errors in future).

The below problem was fixed by reinstallation of openvpn3 package from AUR with clean rebuild.

I got the same problem:

Hey, had the same issue as below when trying to start a session. I tried reinstalling the AUR pkg, but there are build errors. I have glib2 v2.76.4, but to me this looks related to protobuf:

Hey now I have (with/without downgrade 'glib2=2.74.6')

openvpn3 session-start --config client.ovpn
** ERROR ** Failed preparing proxy: Error calling StartServiceByName for net.openvpn.v3.sessions: Launch helper exited with unknown return code 127

Can someone downgrade glib and then modify the openvpn makefile with -static in the linker options so that way it just becomes part of the bin? I had path issues when I tried and couldn't quite figure out how options were passed from the PKGBUILD -> bootstrap -> makefile. I need another few hours of tinkering to get it to work but won't be able to dedicate the time for another few days, hoping someone can get to it first, if not I'll post the instructions and then hopefully someone can merge it in for everyone.

Not sure it's related to the issue others are having with glib2 but for about a year I've had to use a downgraded version of protobuf since openpvn3 does not work with newer versions for some reason. It also segfaults early so cannot do any logging.

Upgrading to 20-1 doesn't resolve the issue. Downgrading glib2 still the only way to run it.

I know this doesn't solve what's going on with OpenVPN3, but I had to find a solution for my wife's work from home days. So, I swallowed my pride and dare I say it - created a bootable flash drive with Windows 10 and an OpenVPN3 client on it. It kept my Endeavour OS system intact, but easily solved our problem. It works great and boots up quick.

When I downgraded glib2 to 2.74.6, I couldn't use pacman or yay to update since timeshift would crash before updating.

To get around this you will need to revert the downgrade by running. sudo SKIP_AUTOSNAP=1 pacman -S glib2

During the downgrade if you chose to ignore the package then you will need to revert that too.
sudo vim /etc/pacman.conf You should see glib2 mentioned near the top under options.
