The documentation says is better to use ## Oracle Linux
It is recommend to only use Red Hat Enterprise Linux, Oracle Linux or CentOS for Pritunl servers.
Compatibility with rocky linux is in the roadmap?
It’s really a problem install it on ubuntu server? will be any real difference?
The Pritunl server a dual web server design with an internal and external web server. The external web server is run in a separate process and will sanitize incoming web requests in addition to handling SSL. Both processes have SELinux policies, this provides a high level of proctection from RCE attacks on the external pritunl-web process.
The Oracle Linux 8 repository should work on Rocky Linux and AlmaLinux.
