Yesterday I tried to upgrade one of my Pis from Raspbian 7 (JessieWheezy) to Raspbian 8 (WheezyJessie) and finally to Raspbian 9 (Stretch). (The upgrade to Buster won’t happen until I get a bigger SD card.)

sudo apt-get update gave me the following error:

Something wicked happened resolving 'raspberrypi.collabora.com:http' (-5 - No address associated with hostname)

APT would not pull any updates because of this error. All other repos were reachable, which pretty much rules out any network/DNS problems on my end as the cause. Also, https://downforeveryoneorjustme.com/raspberrypi.collabora.com reports the site as down—which looks like the repo has gone away.

Looking at my package sources, I noticed that this was only one of several repos. Disabling raspberrypi.collabora.com allowed me to do all the upgrades I needed, and the system seems to work.

When I compare this system with another Pi which I set up with Stretch from the start, I notice the Stretch system does not have this repo (although the host names for the other package sources differ as well).


  • What is/was the raspberrypi.collabora.com repository for?
  • Will disabling it cut off some packages from updates, or do the other repos now provide these packages?
  • What is the correct way of migrating away from it (i.e. without leaving behind any non-upgradeable packages)?
  • To answer your third question: the correct way of migrating is to start with a fresh flashed Raspbian Buster image. I hope you have the original installation of Raspbian 7 (Wheezy not Jessie) still available. Fixing issues from full upgrades over 4 versions isn't worth the effort compared with starting a new installation. – Ingo Mar 15 at 15:04

    That stuff was a web browser, the RPF folks spent a fortune on getting it developed and it was utter cr**. They replaced Collabra with Google Chromium. – Dougie Mar 15 at 15:31
  • @Ingo Effort depends largely on how well the old installation is documented. If you have a full documentation, starting from scratch may work. If not, recreating everything may not be worth the odd risk of the upgrade breaking something. For that particular system, the upgrade went smoothly. – user149408 Mar 16 at 12:16

This is what it was for according to their website at https://www.collabora.com/about-us/our-work.html

They might have provided a browser or driver's according to my quick read 👍


They created the desktop environment after a tiny bit more reading of their webpage 😀
