Pritunl VPN-Client for Alpine Linux

Pritunl Pritunl VPN
1

Dear @zach ,

I finally managed to setup my Pritunl VPN-Servers.
I would love to use Pritunl VPN-Client in a small (minimal) Alpine Linux LXC-Container on my Proxmox-Homeserver.

Any change that Alpine Linux will be supported for pritunl-client?

Best regards,
MacGyver

If you only need the CLI client it’s very easy to install it directly from the source. The pritunl/pritunl-client repository has information on doing this.

All of the full build scripts for Pritunl packages are in the pritunl/pritunl-pacur repository. This can be used with AI to create source installations for other distributions and other packages including the Electron GUI client.
