-  - NOTE: The Debian project is no longer using a standard package name for `libasound2`. Not to worry, apt will automatically select the `libasound2t64` packages it needs. For all derivative distributions, therefore, the package name will remain "libasound2". 
+  - NOTE: Debian 13 and Ubuntu 24.04 renamed `libasound2` to `libasound2t64` as part of the Y2038 transition, but not every derivative followed (Devuan, for example, still ships `libasound2`). The installer probes `apt-cache` at runtime and selects whichever name is a real package on the host, so this is handled transparently across the Debian family.
 - Devuan 6.1 Excalibur 
   - NOTE: server-mode installation is unavailable here, because Devuan does not use systemd. The installer detects this and refuses `SYSTEMD_MODE=install` up front rather than failing mid-install.
 - Manjaro
