Ao executar “apt install programa” ou “apt update” no Debian ocorre o seguinte erro:
E: Release file for http://deb.debian.org/debian/dists/buster/InRelease is not valid yet (invalid for another 248d 13h 20min 17s). Updates for this repository will not be applied. E: Release file for http://deb.debian.org/debian/dists/buster-updates/InRelease is not valid yet (invalid for another 279d 16h 2min 2s). Updates for this repository will not be applied.

Esse erro geralmente acontece por conta da data e hora do sistema estarem erradas.
Ajuste a data e hora usando, por exemplo, o comando date e tente instalar ou atualizar novamente.
