Workaround: I just tried using NetworkManager-openvpn from 15.2 on 15.1 and it works fine! In 5 tests (connect / disconnect) there where no more dangling openvpn processes. (before about every second time an openvpn stayed active after disconnect) (version numbers in urls may change because 15.2 is still in beta) wget https://download.opensuse.org/distribution/leap/15.2/repo/oss/x86_64/NetworkManager-openvpn-1.8.10-lp152.1.3.x86_64.rpm wget https://download.opensuse.org/distribution/leap/15.2/repo/oss/noarch/NetworkManager-openvpn-lang-1.8.10-lp152.1.3.noarch.rpm and if you use gnome wget https://download.opensuse.org/distribution/leap/15.2/repo/oss/x86_64/NetworkManager-openvpn-gnome-1.8.10-lp152.1.3.x86_64.rpm (install all at once to avoid dependency trouble) sudo rpm -Uhv NetworkManager-openvpn-*
