Help installing openvpn3 client on UT

stack24

Hello There!

I'm new here and this is my first post/question!

Context

On android I installed the OpenVPN Client Connect app which enables me to make use of CloudConnexa VPN Networks functionality. Unfortunately, the openvpn which comes installed with UT is not compatible for what I need... That said, I would like to install openvpn3 client on my device running ubuntuTouch following this tutorial: CloudConnexa.

Progress so far

I was able to run some of the commands after mounting filesystem as rw, then re-mounting it to ro of course. But when I ran

apt install openvpn3

I got errors relating to _apt user so I temporarily create this new user and then I got the following errors:

phablet@ubuntu-phablet:~$ sudo apt --fix-broken install

And I'm stuck from here on....

Does anyone know if it's possible at all to install openvpn3 client on UT? Else is anyone aware of an alternative client/solution?

Thanks!

Hey! I don't have a lot of knowledge myself, but I'll reply since nobody else replied so far. I'll be corrected if I got something wrong!

The base Ubuntu Touch install is immutable, e. g. the filesystem is read-only and you can't install anything with APT. This is I believe for security and to simplify OTA updates. I believe you can change it to make it read-write, but this will prevent some other stuff from working fine. The only well-supported way to add stuff on Ubuntu Touch is though Click packages, that you can get from the Open Store.

That being said, I believe Ubuntu Touch already supports OpenVPN-style configuration in the Settings app, so there should be no need to install anything extra. I'm not sure if you can provide it a ready-made configuration file, but I know you can at least configure it manually.

EDIT: I just remembered that you can install stuff from APT on your phone, but only in a Libertine container (Creating a container can be all done from GUI, or from CLI, at your preference). That works for local apps, but not for anything that may need full access to the system like a VPN does, so it won't be useful in this instance.
