Weak Algorithm Missing Sources ondrej php

Are you getting either the “Missing Signed-By in the sources.list” N error or, a W error “uses weak algorithm” error? Both of these messages can be resolved with the two steps below – delete ondrej sources files, re-add the ondrej repository.

We’re talking bout Ubuntu 24.4 Noble Numbat here.

Results from checking apt get updates. Weak Algorithm. Doesn’t sound good. Launchpad. Abort.

  • W: http://ppa.launchpad.net/ondrej/php/ubuntu/dists/noble/InRelease: Signature by key 14AA40EC0831756756D7F66C4F4EA0AAE5267A6C uses weak algorithm (rsa1024)
  • N: Missing Signed-By in the sources.list(5) entry for ‘http://ppa.launchpad.net/ondrej/php/ubuntu’

For fun. Run the apt remove command. It will likely fail, that’s why you’re here.

  • sudo add-apt-repository –remove ppa:ondrej/php (ondrej’s like no please man don’t do that, please, ok)

Delete the following two files from /etc/apt/sources.list.d  – mine had names as thus

  • ondrej-ubuntu-php-focal.list.distUpgrade
  • ondrej-ubuntu-php-focal.sources

Run the apt install command!

  • sudo add-apt-repository ppa:ondrej/php

Run an update. No weak keys in my house!

  • We’re all PPA’d up
