yes, it was installed inside a jail, when i first deleted the jail, somehow the package didn't uninstall for some reason, i could still browse the files with windows in my jails partition, also shell still showed that openvpn was installed, what i did was create a new jail using the same name, then used "pkg delete openvpn" like
dlavigne suggested, then i deleted the jail again, seems to be uninstalled successfully now, thanks a lot!
there is one folder left called ".Openvpn.meta" containing a file called "jailtype", should i leave that as is or recommended to remove it as well ?
edit: used "chmod -R 777" on that folder and deleted it as well.
thank you.
