I'm working on EL 7.4 (base repo) + EPEL.
I tried to make pptp (I know it's broken, not my decision) connection
via NetworkManager. Some (undefined) time ago it worked as expected.
Unfortunately both fresh and updated systems don't have option in add
vpn popup (included vpn1.png).
Then I tried to recompile current version
reinstall and restart NetworkManager. Still without any success.
Then I take Fedora newer package
then use same procedure (recompile, update, restart NM). The option for
ptpp in menu is now present (vpn2.png). I configured fresh vpn on other
computer with Fedora package, so it's working (at least for me).
I would love to hear if anyone can reproduce, and if it's not only my
problem if someone could pull this package.
