Earlier quoted context omitted.
isn't it a static binary? Can't you do it the old-school sysadmin way and pull down a binary from github releases and update a symbolic link?
yes, but that’s not as simple as apt automatic upgrades
1. systemd timer
2. curl github api
3. if new release, fetch, verify checksum
4. update symlink
5. restart service
i don’t think repackaging is actually easier here, for main services of a system is ok to skip the package manager.
