Lots of things happened and at one moment it seemed to break my install completely. After running apt-get update && sudo apt-get upgrade I was greeted by 27 vulnerabilities which I was able to revolve by running the following commands:
fwconsole ma refreshsignatures
fwconsole chown
fwconsole reload
In the end I wasn’t able to dial *97 while *98 did work. And incoming calls were dropped. Meanwhile I rolled back a snapshot.
