$ flatpak enter org.remmina.Remmina
$ flatpak-spawn --host true
Portal call failed: org.freedesktop.DBus.Error.ServiceUnknown

Resolution: use something like Flatseal to give Remmina access to org.freedesktop.Flatpak (not just org.freedesktop.portal.Flatpak)

Workaround for DNS being down after disconnecting from SSTP VPN

When to use?

When you are using network-manager-sstp with Automatic DNS configuration, but don't have resolveconf installed. This will trigger the bug, and make your /etc/resolv.conf readable only by root.

How to use this fix?

Copy content of ip-up.local.sh to /etc/ppp/ip-up.local, and sudo chmod +x /etc/ppp/ip-up.local.
