Can't update or use package manager -- gpg error

CRGreathouse · #1 (**permalink**) 2 Weeks Ago

Code:

W: GPG error: http://archive.canonical.com karmic Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic-updates Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic-security Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic-proposed Release: Unknown error executing gpgv

This occurs on using the update manager, package manager, apt-get update, etc. Any ideas? I've tried deleting the cached files, changing my server, checking that my date & time are correct (signing can be time sensitive), updating gpg (it was already at the latest), and maybe some other things I've forgotten.

System: Ubuntu Karmic amd64

I even tried removing and reinstalling gpg, which is a hassle because many programs depend on it. I also installed (unverified!) updates and restarted; no luck.

I've been able to get around this so far by skipping gpg validation of things that I install -- but obviously this is less than ideal (and subject to man-in-the-middle attacks, etc.).

Code:

sudo apt-get remove ubuntu-keyring
sudo apt-get --yes -q --allow-unauthenticated install ubuntu-keyring

I ran

Code:

sudo apt-get remove ubuntu-keyring

and ubuntu-keyring and ubuntu-minimal were uninstalled. I then ran

Code:

sudo apt-get --yes -q --allow-unauthenticated install ubuntu-keyring ubuntu-minimal

Both were reinstalled. Along with the standard messages, apt-get displayed

Code:

gpg: symbol lookup error: /usr/local/lib/libreadline.so.6: undefined symbol: PC
gpg: symbol lookup error: /usr/local/lib/libreadline.so.6: undefined symbol: PC

and the problem still remains: sudo apt-get update gives

Code:

W: GPG error: http://archive.canonical.com karmic Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic-updates Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic-security Release: Unknown error executing gpgv
W: GPG error: http://us.archive.ubuntu.com karmic-proposed Release: Unknown error executing gpgv

Thanks for trying, though.
