Issue body
Snapcraft version 7.4.3, Rev 9362
While attempting to build a snap, it fails almost immediately with the error "Failed to install GPG key: Key must be a single key, not multiple.". Attempting to send error data when prompted results in: "Encountered an issue while trying to submit the report: unhashable type: 'AptGPGKeyInstallError'" and a suggestion to post here.
The problem seems to be when including puppet bolt via the "package-repositories" directive and an associated .asc key file. Presumably there is something in the key that snapcraft cannot parse any more.
This issue looks like it has been reported elsewhere at https://forum.snapcraft.io/t/issue-with-gpg-key/35675/9 and https://github.com/snapcore/snapcraft/issues/4224, but I thought I'd add it here because the "report error data?" prompt asked me to.
