[Bug 979630] Re: Unable to re-install maas after truncating/flushing database

[Newell Jensen]

I ran into the problem mentioned (on install) and I also ran into the
same problem when trying to remove maas packages:

ubuntu at maas:~$ sudo apt-get autoremove maas maas-dhcp maas-dns
[sudo] password for ubuntu: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages will be REMOVED:
  maas maas-cluster-controller maas-dhcp maas-dns
0 upgraded, 0 newly installed, 4 to remove and 0 not upgraded.
2 not fully installed or removed.
After this operation, 352 kB disk space will be freed.
Do you want to continue? [Y/n] y

This is just extra information and is most likely a result of the first re-install failure.
