I actually noticed during the Lubuntu 11.10 to 12.04 upgrade process, it stated that some packages were being marked obsolete. I checked that list, and found (to my dismay) that qjackctl was one of those packages. In hindsight, I should have elected to keep them all, since there wasn't a way to keep just qjactctl, but I shrugged-it-off, thinking they were replacing it with a newer version, and like an idiot, I accepted what was suggested. But no, the upgrade process marked qjackctl obsolete, and there appears to be no way to undo the damage, other than installing the entire system. - Aere On Mon, 2012-06-18 at 11:17 -0700, ∅ wrote: <BLOCKQUOTE TYPE=CITE> <PRE> i made the same transition-- with qjackctl installed-- with no such problems. i do know i had a current version of qjackctl, though. maybe that was the problem?? try updating in 11.10 before you make the upgrade. check the version of qjackctl you have, too. wxl On 06/18/2012 11:10 AM, Alex Lam S.L. wrote: > 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: > > <A HREF="http://packages.ubuntu.com/oneiric/qjackctl">http://packages.ubuntu.com/oneiric/qjackctl</A> > <A HREF="http://packages.ubuntu.com/precise/qjackctl">http://packages.ubuntu.com/precise/qjackctl</A> > > 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. > > > > On Mon, Jun 18, 2012 at 6:43 PM, Aere Greenway > <<A HREF="mailto:Aere@dvorak-keyboards.com">Aere@dvorak-keyboards.com</A>> wrote: >> All: >> >> In testing the upgrade of one of my MIDI-Music systems from Lubuntu 11.10 >> to Lubuntu 12.04, I encountered a serious problem, and in spite of hours of >> trying, I have been unable to find any way to report the problem (where it >> does not actually cause a crash). >> >> The problem is that the upgrade process for Lubuntu (this problem does not >> occur in the Ubuntu upgrade), the package "qjackctl" is marked obsolete, and >> in doing so, after the upgrade, there is no way (that I know of) to >> re-install it (get it back). >> >> The "qjackctl" package is an essential component for people using MIDI >> music software.
