[Bug 793563] Re: SystemError: E:Type 'sudo' is not known

[blueddy]

I already had this error trying to update 16.04.1 LTS

The problem is that the /var/lib/update-manager/meta-release-lts-
development file doesn't exists on my system.

Basing on :
https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/174266/comments/4

I fixed the problem creating a new one with this content:
