Can this version of QT4 be successfully be installed on Lucid. So many things I try to install depend on this.

Error: Dependency is not satisfiable: libqtcore4 (>= 4:4.7.0~beta1)

Calibre PPA-Lucid is showing 4:4.7.0-0ubuntu4~ppa2, but notes:

PACKAGE BUILD FAILURES (STATUS): -Calibre: It's a problem with qt4, I think, I'm trying a build on my main PPA. Which, if successful, will be copied to this repo.

I've also seen backports available for kubuntu of beta1 and beta2 but I'm running xubuntu and I really don't understand backports anyway.

Backports are

Kubuntu Backports

PPA description

Backports of new versions of KDE and major KDE apps for Kubuntu which are either too large a change or not yet tested enough to go to Ubuntu Backports.

There is available for the Lucid: qt4-x11 (4:4.7.0-0ubuntu2~lucid1~ppa2).

Upgrading from a PPA

I'm running xubuntu and I really don't understand backports anyway.

You could go to the Kubuntu Backports and click the "Read about installing": Upgrade will only upgrade the installed packages (Qt).

Downgrade from the PPA

A package:

:~$ apt-cache show ppa-purge

Description: disables a PPA and reverts to official packages

This program disables a PPA from your Software Sources and reverts your system back to the official Ubuntu packages. You can use this to return your system to normal after testing a new version from a PPA.


It is available from the lucid-backports:

Thank you for the very informative reply. I've added the kubuntu ppa as sugested and upon updating I saw all the qt4 updates ready to be installed but they were grayed out and I was offered an option to do a "Partial Upgrade". After some digging I ran sudo apt-get --dry-run dist-upgrade to find only 1 package to be removed. libqt4-multimedia How do I determine what will be affected from this removal. Please advise if this should be a new question. – akovia Jan 24 '12 at 17:36
It seems that there was changes from the Qt 4.6 to the 4.7. One was the QtMultimedia was replaced by QtMobilities, QtMultimediaKit (by ). After the Lucid the Ubuntu has libqtmultimediakit1 with the Qt 4.7-4.8. If you upgrade to the Qt 4.7 some applications may stop to work - they need the developer attention (new version) to work with the Qt 4.7 or later. Applications that are needing the libqt4-multimedia should have it as a dependency. You should see this with the dry-run/simulation. They will be marked to be removed. – user26687 Jan 24 '12 at 18:34
Thank You! Your answers were more than I had hoped for. – akovia Jan 24 '12 at 19:23
