[R-sig-Debian] Using PPA c2d4u.team on Ubuntu 22.04?

[Matthieu S]

Hi

We recently installed a server with Ubuntu 22.04, and tried to add the nice
c2d4u ppa, with:
sudo add-apt-repository ppa:c2d4u.team/c2d4u4.0+

It leads to error:
E: The repository '
https://ppa.launchpadcontent.net/c2d4u.team/c2d4u4.0+/ubuntu jammy Release'
does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore
disabled by default.

Does it mean I am just impatient and the PPA has not been prepared for the
new version, or should I adjust something in the command?

Thanks!

Matthieu
