Error during apt-get update
8,468
Typically running the following should work:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 99E82A75642AC823
sudo apt-get update
In this case, I don't think this will work because:
-
There is no trusty packages for octave as you can see from here
-
User

no longer maintains a PPA as you can see from here
It is better to remove these PPAs from your sources list. Read an excellent answer from How can I fix a 404 Error when using a PPA or updating my package lists? to know how to do that.

While running
apt-get
i get the following error :-W: GPG error: https://dl.bintray.com Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 99E82A75642AC823 W: Failed to fetch http://ppa.launchpad.net/picaso/octave/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found W: Failed to fetch http://ppa.launchpad.net/picaso/octave/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found W: Failed to fetch http://ppa.launchpad.net/samrog131/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found W: Failed to fetch http://ppa.launchpad.net/samrog131/ppa/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
I have tried a number of solutions each of which failed. I can't install any software using
sudo apt-get update
in their script now :( I have already tried system updates, trying to contact the keyserver (which always returns a timeout)-
Admin almost 9 yearsWhich solutions have you tried already? Mention them or you will only be offered them again!
