Problem with upgrade of Lubuntu 11.10 to 12.04

[Alex Lam S.L.]

Hi there,

This seems to be a problem with Ubuntu rather than Lubuntu, which
relies on the packages provided by the former.

Either case, looking at the package information, "qjackctl" seems very
much alive:

  http://packages.ubuntu.com/oneiric/qjackctl
  http://packages.ubuntu.com/precise/qjackctl

And they seem to be of exact same version between 11.10 (oneiric) and
12.04 (precise).

I have also tried installing the package on my system by (under LXTerminal):

  $> sudo apt-get install qjackctl
  ...
  Need to get 14.5 MB of archives.
  After this operation, 51.5 MB of additional disk space will be used.
  Do you want to continue [Y/n]?

So I can't see immediately where the problem is; the system I have
tested on is a fresh install (instead of an upgrade), but I doubt if
that would cause any differences.

Please try the command above - report back with any error messages if
it fails to install the package.


HTH,
Alex.
