    W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://extras.ubuntu.com oneiric Release: The following signatures were invalid: BADSIG 16126D3A3E5C1192 Ubuntu Extras Archive Automatic Signing Key <ftpmaster@ubuntu.com>

    I have tried the following fixes:

    Code:
    gpg --keyserver keyserver.ubuntu.com –recv 16126D3A3E5C1192
    which returns:

    Code:
    gpg: requesting key 3E5C1192 from hkp server keyserver.ubuntu.com
    gpg: key 3E5C1192: "Ubuntu Extras Archive Automatic Signing Key <ftpmaster@ubuntu.com>" not changed
    gpg: Total number processed: 1
    gpg:              unchanged: 1
    So I then enter:
    Code:
    gpg --export --armor 3E5C1192 | sudo apt-key add -
    which returns:

    Code:
    OK
    I have tried this for several of the invalid signatures but the problems persist.

    I have also tried:

    Code:
    sudo apt-get update && sudo apt-get install -f && sudo apt-get upgrade
    which returns:

    Problems persist.

    I have also tried changing the software sources download server and reinstalling ubuntu-extras-keyring in Synaptic Package Manager. Also, restoring default keys in the Software Sources 'Authentification' tab.


    I have found similar fixes to the above on this forum but none have worked. Any assistance appreciated.

    Re: Updating - signature verification & signatures invalid errors

    You may want to install launchpad-getkeys. I had the same problem minutes ago and it did fix the keys for me

    Code:
    sudo add-apt-repository ppa:nilarimogard/webupd8
    sudo apt-get update
    sudo apt-get install launchpad-getkeys
    then :

    Code:
    sudo launchpad-getkeys

    Thanks Eyden. I have already tried that fix. It appears to work & claims all missing keys have been replaced. But upon running update. I get the same errors.

    Re: Updating - signature verification & signatures invalid errors

    raja.genupula: First Link Method 1:

    Code:
    cd /var/lib/apt
    returned no such directory.

    First Link Method 2:

    Code:
    sudo aptitude -o Acquire::http::No-Cache=True -o Acquire::BrokenProxy=true update
    returned

    sudo: aptitude: command not found

    Link 2 is a fix I have already tried and it did not work.

    Thanks for trying though.

    aptitude was not installed in your system.

    Code:
    sudo apt-get install aptitude
    and try again.

    & i feel surprise about the output of
    cd /var/lib/apt

    if not use mkdir to create that and try again.

    Arrow Re: Updating - signature verification & signatures invalid errors

    raja.genupula: Thank you. It is now fixed. I installed apptitude but that fix still had no effect. However when I came to mkdir /var/lib/apt it was already there. I guess I must have mistyped that line in the fix. Anyway, I completed the fix below and it seems to have worked I get no errors after sudo apt-get-update and update manager is showing system up to date.

    Code:
    $ sudo -i
    
    # apt-get clean
    
    # cd /var/lib/apt
    
    # mv lists lists.old
    
    # mkdir -p lists/partial
    
    # apt-get clean
    
    # apt-get update
    ref: link
