Try the following packages:

extra/protobuf
extra/protobuf-c
extra/python-protobuf
extra/python2-protobuf

The Protocoll Buffers is coming indeed from Google: https://en.wikipedia.org/wiki/Protocol_Buffers

I've added Dino onto the spreadsheet, but I also think that we must have the development-team when the first testing-candidates are out. So my recommendation would be: Installation of "Test"-system into a VM perhaps and trying to compile concurrent applications and packages, therefore also sharing the PKGBUILD-scripts here. What do you think?

thx throgh its working now using "extra/protobuf" without protobuf-c.....

for the "test-system" i think it would be a great idea maybe doing so we could help the development-team fixing or pointing out bugs, maybe we start by opening up a new post just for that and others could join and help sharing the PKGBUILD-scripts maybe a default config for some apps like gajim here omemo should be add wen you first install like this we make sure a basic security and privacy settings are in place for us and new people who wanna try out hyperbola.
Take the lead im in

i also add python2-axolotl cause i found it on Optional dependencies for gajim it got fixed then using Python-Axolotl from hyperbola pkg list or this PKGBUILD, i get a new error

Warning: OMEMO cant import Google Protobuf, you can find help in the GitHub Wiki
this scared me a lot

You should tryout to compile the package python-axolotl by yourself local. After installation the issue should be vanished. Regarding Dino: You can add this to the spreadsheet. Be careful: The application cannot be added when dbus, elogind and others are needed!

The mentioned two other errors seem to have more to do with the server-communication itself. Not especially with the client, but this is just a first guess from my side.
