[Bug 1310341] [NEW] Upgrade from Saucy to Trusty removed my user from sudoers

[Jeff Lane]

Public bug reported:

I just did a full upgrade from Saucy to Trusty.

After completing the upgrade and rebooting and logging in, I opened a
terminal an attempted to add a ppa so I could try out a calendar
indicator applet.

However, I just discovered that the upgrade destroyed my sudoers file
and my ONLY user account no longer has sudo access.

Because of this, I can't do ANYTHING on my system because I don't have
sudoers.

So my upgrade from Saucy to Trusty has, right off the bat, left me with
an unusable system I must now repair.
