upgrade problems
 
I am trying to upgrade from ubuntu 6.x to 7.10, but have encountered a problem: a broken package I cannot fix, and that will not go away.

Code:

sudo dpkg --configure -a
dpkg: dependency problems prevent configuration of libjack0.100.0-0:
 libjack0.100.0-0 depends on libjack0 (>= 0.103.0-6ubuntu1); however:
  Package libjack0 is not installed.
dpkg: error processing libjack0.100.0-0 (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 libjack0.100.0-0
$ sudo dpkg --remove libjack0.100.0
dpkg - warning: ignoring request to remove libjack0.100.0 which isn't installed.
$ sudo dpkg --install libjack0
dpkg: error processing libjack0 (--install):
 cannot access archive: No such file or directory
Errors were encountered while processing:
 libjack0

If I try to fix the problem via adept, I get a message that the process could not be completed, possibly due to packages breaking.

I think jackd/libjack and their dependancies/installation have changed so much since U6, and that you have two choices,

1. Back up your U6 as needed, and do a fresh U7 install
2. Use synaptic or similar to remove all jack related things
from your U6 system before 'upgrading'. And first, confirm that your
priorities are fully supported by the U7 you have, and that you are
not defeated by hardware or software not fully supported out
of the gate.

I find that upgrades that traverse multiple releases are bound
to break something you like, and since so much has changed in the
several Ubuntu releases, you may as well install a full new version,
and then add your preferences when you have a working install. When
upgrading skips several KDE or Gnome releases, even the eyecandy and
settings in your /home/user may fail to compute, another vote for a clean install. Mepis was the distro that seemed most proficient at preserving a working /home partition, usually only a couple KDE tweaks needed re-enabling, theme, mail and browser etc were all ready to go
after a new install. Hope this helps.
