Troubles (errors) running Karmic 'update-manager'

SaintDanBert · 02-07-2010, 11:33 AM

Is there a canonical(sic) way to resolve update-manager errors about missing keys and indices and similar?

When I run update-manager under Ubuntu Karmic, I get these errors:

Code:

GPG error: http://ppa.launchpad.net karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B152F042D246C25DFailed to fetch http://ppa.launchpad.net/madman2k/ubuntu/dists/karmic/main/binary-i386/Packages.gz  404  Not Found

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

I've done much google searching seeking missing or updated parts without success.

The signature error should not stop you (but notify you so you paid attention to the thing), but that looks like it can't get anything from those reposities. Trying to access the http address fails, so probably that directory does not exist on the server anymore, or is temporarily unaccessible.

The only way to "solve" that is to remove (or comment out) the lines from the list of apt reposities. Either use the graphical tool with which you manage the package reposity information, or manually edit apt sources.list in /etc/apt/.

I'm running Lucid and had all of my GPG keys disappear from Software Sources, Synaptic, Update Manager, etc. The result was a string of error messages similar to what you've described. So, in case it's the same problem...

Further investigation led to it being caused by an error in libreadline.so.6 which caused a parsing error in GPG.

Further investigation (and comparison with a working system) showed a copy of libreadline.so.6 in /usr/local/lib. There are also linked copies in /usr/lib/ and /lib. I have no idea how the extra copy got into /usr/local/lib. It wasn't the same as the others.

The solution was to delete /usr/local/lib/libreadline.so.6 and replace it with a link to /lib/libreadline.so.6.
After that, all my links to GPG keys reappeared under the "authentication" tabs and the error messages stopped.

Good Luck.
