I do see in the apt-key manpage that apt-key is deprecated as of Focal and will be removed after Debian 11 / Ubuntu J/22.04. In the meantime, the `cp some-repo-key.gpg /etc/apt/trusted.gpg.d` method has been brought to the customer as a "workaround" / the new correct method. The signed-by option is a good idea, too! Thank you for your response letting us know that a change to apt-key will be skipped. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931178 Title: apt-key fails when POSIXLY_CORRECT environmental variable is set To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1931178/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
