Upgrade to Debian 12 "bookworm"; Debian 10 "buster" is EOL.

[bashimao]

Debian 10 "Buster" is end-of-life and doesn't receive security updates anymore for quite a while.

Proposed solution

Switch to Debian 12 "Bookworm" because Debian 11 "Bullseye" will go EOL next month.

Debian Version	Codename	Standard Security EOL	Long Term Support (LTS) EOL	Status
Debian 10	Buster	September 2022	June 2024	Fully End-of-Life
Debian 11	Bullseye	August 2024	August 2026	Near EOL (LTS active)
Debian 12	Bookworm	July 2026	June 2028	Active (LTS transition)
Debian 13	Trixie	August 2028	June 2030	Current Stable

To replicate the problem

Note that the buster APT repos aren't even available via Debian's main mirror anymore.
