the firefox update fails because the cairo-dock package and five other cairo-dock-packages have an incorrect hash sum and thus cannot be downloaded. I cannot find any way to report such a problem since "ubuntu-bug cairo-dock" tells me that such a package does not exist. Very frustrating.

Could you post the output of apt-cache policy cairo-dock? Try re-downloading the package by clearing your cache (apt-get clean) followed by an refresh (apt-get update) and finally the upgrade (apt-get upgrade) – Lekensteyn Jun 22 '11 at 7:37
this is after apt-get clean/apt-get update/apt-get upgrade : apt-cache policy cairo-dock cairo-dock: Installiert: 2.3.0~2-2ubuntu1~natty Kandidat: 2.3.0~3-1ubuntu0~natty Versionstabelle: 2.3.0~3-1ubuntu0~natty 0 500 natty/main i386 Packages *** 2.3.0~2-2ubuntu1~natty 0 100 /var/lib/dpkg/status 2.3.0~1-0ubuntu1 0 500… natty/universe i386 Packages – bkleine Jun 22 '11 at 8:07
problem gone! questions remains where to report? What should I expect when I type "ubuntu-bug cairo-dock"? – bkleine Jun 22 '11 at 8:18
Probably not a problem with the package, but an interrupted update or a temporary network problem caused the hash mismatch. – enzotib Jun 22 '11 at 8:55

The package cairo-dock is a meta package for cairo-dock-core and for cairo-dock-pulg-ins. You may be able to file an ubuntu bug against cairo-dock-core.

A valuable source for help and additional information is the well maintained upstream web-site for Glx-Dock. They even have an active forum to discuss features and bugs.
