I can't update my Ubuntu cause it says:

Requires installation of untrusted packages

The action would require the installation of packages from not authenticated sources.

chromium-browser chromium-browser-l10n chromium-codecs-ffmpeg

Why is that? I never changed anything and it always used to work fine.


If you haven't installed any PPA's for Chromium, press the Reload button in the package manager (the command line equivalent is sudo apt-get update). If the problem persists, wait a day before retrying. The mirror is possibly not completely updated yet or a proxy is caching the contents.



sudo add-apt-repository ppa:chromium-daily/ppa

That should authenticate your chromium packages and let you download the updates, etc.

    The chromium-daily/ppa PPA contains a version that is updated every day from the development code which may be unstable. Do not recommend it for the average user. – Lekensteyn Oct 31 '11 at 19:42
  • Ok thanks for the info. So you are saying that no ppa is necessary at all, and the problem will go away? I had the problem too... – RhZ Nov 1 '11 at 4:11
  • If you want a more recent version of Chromium, use ppa:chromium-daily/stable, but for normal usage, you do not need a PPA for it. Issues like these will go away in a short time. – Lekensteyn Nov 1 '11 at 12:49
  • Thanks so much, its really helpful to me and probably others. I am signing up to work with this community :-) – RhZ Nov 1 '11 at 15:41
