Hello,

* My configuration is the following :

Description: Ubuntu 8.04.1
Release: 8.04

libcairo2:
  Installé : 1.6.0-0ubuntu2
  Candidat : 1.6.0-0ubuntu2
 Table de version :
 *** 1.6.0-0ubuntu2 0
        500 http://fr.archive.ubuntu.com hardy-updates/main Packages
        100 /var/lib/dpkg/status
     1.6.0-0ubuntu1 0
        500 http://fr.archive.ubuntu.com hardy/main Packages

libpixman-1-0:
  Installé : 0.10.0-0ubuntu1
  Candidat : 0.10.0-0ubuntu1
 Table de version :
 *** 0.10.0-0ubuntu1 0

        100 /var/lib/dpkg/status

My desktop is the one provided by Xubuntu 8.04 x86_64 release after all security updates until today.

* What happened :

When I try to launch gdebi-gtk or firefox-3.0.3 from a terminal, I've got the following error :

For example in gedib-gtk :

/usr/lib/python2.5/site-packages/apt/__init__.py:18: FutureWarning: apt API not stable yet
  warnings.warn("apt API not stable yet", FutureWarning)
Traceback (most recent call last):
  File "/usr/bin/gdebi-gtk", line 31, in <module>
    from GDebi.GDebi import GDebi
  File "/usr/lib/python2.5/site-packages/GDebi/GDebi.py", line 35, in <module>
    import gtk, gtk.glade
  File "/var/lib/python-support/python2.5/gtk-2.0/gtk/__init__.py", line 48, in <module>
    from gtk import _gtk
ImportError: /usr/lib/libcairo.so.2: undefined symbol: pixman_format_supported_destination

The last line is the same in firefox-3.0.3

I already try de reinstall libcairo2 and libpixman-1-0 with apt-get install --reinstall.
(and of course firefox and gdebi too)

could you run ldd /usr/lib/libcairo.so.2 and copy the log to a comment? you likely have a local version hijacking the distribution one

Hello,

I'm sorry, but the system was too much unstable in the above state : I needed to reinstall quickly.
I am now in 8.10 version, and I cannot reproduce the bug.

I hope that nobody will encounter the same desagreement as it is very stressful.

PS: I was thinking that "apt-get install --reinstall" would have overriding the local version with the version on the Ubuntu repository, isn't it ?

[Sebastien Bacher (seb128)]

the packaging system doesn't use the local directory it's meant as a way to override system version and that's what you have been doing, reinstalling the package doesn't change things you did in the local directory, that's not an ubuntu bug
