What is the easiest way to resolve apt-get BADSIG GPG errors?

Okay, usually I run an apt-get update and upgrade about once a day. Now suddenly it's telling me this:

Fetched 666 B in 6s (105 B/s)

W: Failed to fetch ttp://extras.ubuntu.com/ubuntu/dists/oneiric/Release  

W: Failed to fetch ttp://gb.archive.ubuntu.com/ubuntu/dists/oneiric-backports/Release  

W: Some index files failed to download. They have been ignored, or old ones used instead.

Now, in all my time of using Ubuntu I have never seen this, so I am quite confused. Any help would be much appreciated.

Thankyou,

Ross

It seems to be a bug. There is solution described which rebuilds the cache, see "Invalid signature for extras.ubuntu.com" and this worked for me.

It has just started this morning happening again (2/12/11:12:00 GMT). I presume that something messed up the automatic signing process and it will be back when the next update is pushed through.

I've had the same problem recently with es.archive.ubuntu.com and I agree with Stuart on that this is a temporary failure.

In the meantime, I suggest the following workaround:

  • Launch Software Sources
  • Select Main Server from the Download from dropdown list

That will change your sources from gb.archive.ubuntu.com to just archive.ubuntu.com wich should work fine. Alternatively, you can look at Other... and select another server in the UK.
