Just opening and closing an issue so that those who need the help can find it easily:
apt update (or apt-get update) fails with a PPA error:

E: Repository 'https://ppa.launchpadcontent.net/ondrej/php/ubuntu jammy InRelease' changed its 'Label' value from 'PPA for PHP' to 'Use packages.sury.org/php instead'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
^^^^^
The package maintainer confirms this is a legit name change (and not some kind of PPA supply chain attack (see https://codeberg.org/oerdnj/deb.sury.org/issues/91)
so it is safe to update the ppa description as follows by running apt update manually, and accepting the change:
root@mailhost
