Just edited the post quoted above to prevent more bricked devices as the pc-suite update did already (just a few but that's enough I guess)

This quoted post is not true, OTA update is available but there are packages conflicting with it if it tells you to use pc-suite!
If you look at the "info" tab of the package you will get notice of the conflict. if you now try to remove the package with "apt-get remove <package>" it will tell you the depending programs you then easily uninstall via app-manager. After you have done this you should be able to upgrade OTA.

Do not "apt-get dist-upgrade", it worked before but didn't most of this time. I would suggest do not even do "apt-get upgrade" as it will upgrade even with packages on hold back status if one of the conflicting libraries is installed. There is an installer script in the packages not conflicting, uninstalling most of the packages which wont revert that as the held back packages are missing.
