I have the same issue:

W: GPG error: http://download.opensuse.org/repositories/shells:/zsh-users:/zsh-syntax-highlighting/xUbuntu_22.04 InRelease: The following signatures were invalid: EXPKEYSIG 767B5F350F20116F shells:zsh-users OBS Project <shells:zsh-users@build.opensuse.org> E: The repository 'http://download.opensuse.org/repositories/shells:/zsh-users:/zsh-syntax-highlighting/xUbuntu_22.04 InRelease' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
