Comment 14 for bug 1331914

Canonical is supposedly working on migrating 1024-bit repositories to 4096-bit keys... because the tooling literally does not even work with them anymore.

https://bugs.launchpad.net/launchpad/+bug/2053281#:~:text=this%20is%20a%20known%20issue%20and%20we%20are%20working%20on%20rotating%20the%20keys%20of%20the%20affected%20PPAs%20with%201024%2Dbit%20RSA%20keys%20to%204096%2Dbit%20RSA%20keys.

Still no allowing users to change their keys.
