Ubuntu – Apt-get 403 Forbidden, but accessible in the browser


I've noticed that running apt-get update recently has resulted in quite a few ppa's returning "403 Forbidden". In and effort to clean them up I had a look:

W: Failed to fetch http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu/dists/raring/main/binary-amd64/Packages  403  Forbidden

W: Failed to fetch http://ppa.launchpad.net/gnome3-team/gnome3/ubuntu/dists/raring/main/binary-i386/Packages  403  Forbidden

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

The strange things is, if I copy these URLs into my browser I can access the files just fine. Why would apt-get report "403 Forbidden" if they're still accessible? I tried re-adding the ppa through add-apt-repository which downloads the signing key again, and it still reported "403 Forbidden".

  • So it turns out this is an issue with squid-deb-proxy. Unfortunately it doesn't add PPAs and other repositories and just fails with an rather unexpected 403 error.

    You can fix this by adding the repositories to the config file:


    # launchpad personal package archives (disabled by default) 

    Of course, uninstalling squid-deb-proxy also works around the issue:

    apt-get remove squid-deb-proxy
