[Bug 944452] Re: Essential packages will be removed "lzma (due to dpkg)" when doing dist-upgrade

[vincecate]

I have this problem on 3 different machines that I want to upgrade from
lucid to precise.   I tried the fix of above but it did not work for me:

root at mediapc2:/etc/apt# apt-get install dpkg
Reading package lists... Done
Building dependency tree

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
  gnome-icon-theme: Breaks: gnome-games (< 1:2.30.2-1) but 1:2.30.0-0ubuntu6 is to be installed

       Breaks: network-manager-pptp (<= 0.8.0.999-1) but 0.8-0ubuntu3 is to be installed
E: Broken packages


Is it safe to say "Yes, do as I say" on the dist-upgrade?

Is there any other fix?

Can anyone see how to fix the fix for me?

Any other work around?

If I have this on 3 fully upgraded lucid machines it would seem lots of
people should have seen this problem or that it should have been fixed
in the last year.  But I have searched for awhile and I am not finding a
work around that works for me.

Please help!
