consider disabling apt-secure's Label check in Ubuntu

[Paul Collins]

As of 1.5 (per apt-secure(8)) apt checks and warns if a repository's Label value changes.

This probably makes sense for Debian, where folks may be tracking stable instead of buster, and will want to be warned when stable starts pointing somewhere else.

However, Ubuntu doesn't have such repository aliases and, furthermore, for PPAs, the Label value is populated from the "display name" of the PPA. This means that a PPA owner, fixing what they may assume is a simple typo, will require their users to take action before they receive further updates from the PPA, which is less than ideal.

Please consider disabling this check by default in Ubuntu, if only for PPAs.

The check is there to ensure that your pins don't suddenly behave differently after an apt update. This still applies to PPAs.
