Package: openvpn Version: 2.4.7-1 Severity: normal Dear Maintainer,
I am running openvpn in a Linux container. I have upgraded openvpn from stretch to buster version. I have tried to start openvpn with "systemctl start openvpn". The error in the syslog is: Sep 10 00:31:17 vpn systemd[1]: Starting OpenVPN connection to server... Sep 10 00:31:17 vpn systemd[3766]: openvpn@server.service: Failed to set up mount namespacing: Permission denied Sep 10 00:31:17 vpn systemd[3766]: openvpn@server.service: Failed at step NAMESPACE spawning /usr/sbin/openvpn: Permission denied Sep 10 00:31:17 vpn systemd[1]: openvpn@server.service: Main process exited, code=exited, status=226/NAMESPACE Sep 10 00:31:17 vpn systemd[1]: openvpn@server.service: Failed with result 'exit-code'. Sep 10 00:31:17 vpn systemd[1]: Failed to start OpenVPN connection to server. I would expect openvpn to start normally without errors. I have tried to add the following lines to the systemd unit, but it has not helped: PrivateTmp=false NoNewPrivileges=yes I have tried to manually run openvpn with these commands: /usr/sbin/openvpn --daemon ovpn-server --status /run/openvpn/server.status 10 --cd /etc/openvpn --config /etc/openvpn/server.conf --writepid /run/openvpn/server.pid openvpn --config /etc/openvpn/server.conf Both commands were successful.
