Last night I installed EasyPeasy 1.5, which is an Ubuntu Jaunty
distribution. It ran one series of upgrades almost fine (there
was one error message in amongst that; anybody know where I could
find a log of errors?) While it was installing all the initial
patches and upgrades, I also restored my home directory including
some of the dotfiles (but not .gnome2* or anything that looked
like it would interfere with upgrades!)
After both of those operations were finished, apt-get and the
update manager are now broken, or at least their connections to
two of the repositories. The update manager error message is:
W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://us.archive.ubuntu.com jaunty Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster at ubuntu.com>
W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.GPG error: http://ppa.launchpad.net jaunty Release: The following signatures were invalid: BADSIG 3B22AB97AF1CDFA9 Launchpad PPA for Ubuntu-X
W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/jaunty/Release
W: Failed to fetch http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu/dists/jaunty/Release
W: Some index files failed to download, they have been ignored, or old ones used instead.
The error I'm getting from apt-get is "E: Package <foo> has no installation candidate".
How do I troubleshoot the GPG key problem? I suspect that may
be at the root of things.
