Ubuntu – Qt4-x11 4.4.7.0 in Lucid

10.04backportqtxubuntu

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

    https://help.ubuntu.com/community/UbuntuBackports

    Kubuntu Backports

    https://launchpad.net/~kubuntu-ppa/+archive/backports:

    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": https://launchpad.net/+help-soyuz/ppa-sources-list.html. 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.
