Public bug reported:
Boot a precise instance with kernel option 'apparmor=0'
Install maas-dhcp
ubuntu@ubuntu:~$ sudo apt-get install -y maas-dhcp
Setting up maas-dhcp (1.2+bzr1373+dfsg-0ubuntu1~12.04.1) ...
Warning: unable to find a suitable fs in /proc/mounts, is it mounted?
Use --subdomainfs to override.
dpkg: error processing maas-dhcp (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of maas-dns:
maas-dns depends on maas-dhcp (= 1.2+bzr1373+dfsg-0ubuntu1~12.04.1); however:
Package maas-dhcp is not configured yet.
dpkg: error processing maas-dns (--configure):
dependency problems - leaving unconfigured
Looks like apparmor should not be called in
/var/lib/dpkg/info/maas-dhcp.postinst
and /var/lib/dpkg/info/maas-dhcp.postrm when apparmor is disabled.
Workaround
Boot the machine with apparmor enabled.
