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).
Questions:
- 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)?
