Upgarde to 12.04 - Broken keyring

[Nargren]

Hey everyone!

I've upgraded 2 weeks ago to 12.04 and during the upgrade (not clean install, I said "It should work to just update") I have received a keyring error or something (that I wisely ignored and said "I'll deal with it later).

Now the following things are broken:
-Software center doesn't load/work
-Update manager returns an error

E: ubuntu-keyring: subprocess installed post-installation script returned error exit status 127
E: apt: dependency problems - leaving unconfigured

It downloads the packages, but doesn't install.

I was trying

sudo apt-get -f install

and then

sudo apt-get update

But this happens after running the install command:

E: Sub-process /usr/bin/dpkg returned an error code (1)

Nothing is fixed, update manager cannot install any updates or anything.
Any ideas on what could be done? perhaps something quicker than reinstalling?

Thanks,

Try running the following:

sudo apt-get clean all
sudo apt-get update

[Nargren]

Sorry, error still there

E: ubuntu-keyring: subprocess installed post-installation script returned error exit status 127
E: apt: dependency problems - leaving unconfigured

Packages downloaded again, but installations is interrupted.

[cmont899]

try:

sudo dpkg-reconfigure ubuntu-keyring

[Nargren]

I think I tried this before,

/usr/sbin/dpkg-reconfigure: ubuntu-keyring is broken or not fully installed.

I think I also tried force re-installing it, but no success there either

[cmont899]

i got another:

sudo apt-get install --fix-broken
