Deprecated keys in Ubuntu Repository

Hi all,

I did a fresh install of my workstation OS on my laptop (Linuxmint 21.1)

Went to Ubuntu repository and added the add-apt-repository, won’t install the repository because the signing key is deprecated. Tried to manually install the key shown in the repository and it is deprecated.

Would anyone know when the developer is going to update the repository?


Which repository? What do you want to install?
Please post screenshots, logs, configurations, …
