Before upgrading to Saucy, I had several PPAs installed. As usual, the upgrade process disabled the PPAs. Afterwards, I re-enabled the PPAs in Software Sources (making sure that the release was set to saucy
) and ran an update. Some of the PPAs worked, but others gave 404 errors:
W: Failed to fetch http://ppa.launchpad.net/duplicity-team/ppa/ubuntu/dists/saucy/main/binary-i386/Packages: 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/stackapplet-dev/stackapplet/ubuntu/dists/saucy/main/binary-i386/Packages: 404 Not Found
...
Evidently, this common issue occurs because these PPAs haven't been updated to provide packages for Saucy (when I browse to the PPA URLs, only releases through Raring are listed).
"How can I fix a 404 Error when using a PPA or updating my package lists?" suggests removing the PPAs to fix the errors. However, I don't want to remove these PPAs because I believe they are still maintained. For instance, https://launchpad.net/~stackapplet-dev/+archive/stackapplet had a new upload a few weeks ago. I assume that if I just wait, these PPAs will eventually get updated to support Saucy.
What determines when this happens after a new release of Ubuntu? Does it only happen once the maintainer uploads a new version on Launchpad? How long will I have to wait?
/virtualbox/debian/dists/saucy

, and/stackapplet-dev/stackapplet/ubuntu/dists/saucy
has to be created by the maintainer and populated with the appropriate files. You have to ask them when they will have the time to do it.
