How to use Extended LTS

To benefit from the security updates, you just have to configure APT to use our extended LTS repository.

Adding extended LTS repositories to APT

Installing the freexian archive GPG key

The extended LTS repositories are signed with the following GPG key:

sec   rsa4096 2018-05-28 [SC] [expires: 2027-12-05]
      AB597C4F6F3380BD4B2BEBC2A07310D369055D5A
uid           [ultimate] Extended LTS Repository <sysadmin@freexian.com

To enable this key in your APT configuration, you have the following choices:

  • manually install the freexian-archive-keyring package with wget https://deb.freexian.com/extended-lts/pool/main/f/freexian-archive-keyring/freexian-archive-keyring_2022.06.08_all.deb && sudo dpkg -i freexian-archive-keyring_2022.06.08_all.deb
  • manually fetch the key with sudo wget https://deb.freexian.com/extended-lts/archive-key.gpg -O /etc/apt/trusted.gpg.d/freexian-archive-extended-lts.gpg

You might want to double check that the key fingerprint displayed by apt-key finger matches the one shown above.

Be nice, use local mirrors/caches

There are currently no public mirrors of this service and it runs on a single dedicated server. If you have many machines to keep secure, please make a local mirror (or use some cache) and point your machines to your local mirror (or cache) instead of pointing them to the repositories provided by Freexian.
