On June 2nd We updated the signature on our repositories therefore the keyring package update was released before June 28th automatically on the PCs that have performed the updates. However, it can happen that after June 28, if users have not performed system updates, the same can report signature problems on our repository. In this case, to remedy the problem, you can download and install the keyring package from this link: https://ufficiozero.mirror.garr.it/uzl-deb/portofino/pool/main/u/ufficiozero-keyring/ufficiozero-keyring_2022.06%2Bnmu2_all.deb to solve this problem.
On January 2, 2023 We recreated all our repositories on a new server so if your system gives you an error about the InRelease file or the new key of the new repositories during the updates, don't panic!
