I started using Ubuntu 22.04 and this issue started to occour. The 'add-apt-repository' command adds the gpg key of the PPA repository in the trusted.gpg file (/etc/apt/trusted.gpg)
As commented above, the PPA repositories are not being included in the sources.list file (/etc/apt/sources.list) or in the directory /etc/apt/sources.list.d/<repo-name> with the parameter [signed-by=] Workaround: While the fix doesn't come, the way is to adapt the repository in this way: 1- $ sudo add-apt-repository ppa:author/project 2- $ apt-key list 3- $ gpg --export <repository-fingerprint> | sudo tee /etc/apt/trusted.gpg.d/<repo-name>.gpg 4- $ sudo nano /etc/apt/sources.list.d/repository-name.list 5- Find & Replace: deb http://ppa.launchpad.net/author/project/ubuntu jammy main by deb [signed-by=/etc/apt/trusted.gpg.d/<repo-name>.gpg http://ppa.launchpad.net/author/project/ubuntu jammy main 6- Save the changes and run 'sudo apt update' again -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862764 Title: add-apt-repository should use signed-by To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-apt/+bug/1862764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
