[...] Actually, the instructions are here https://wiki.postgresql.org/wiki/Apt (if you go to https://apt.postgresql.org/ you get redirected to the above wiki page, so the PostgreSQL folks have really taken pains to make sure nobody misses it). Quoting from that page: Quickstart ---------- Import the repository key from https://www.postgresql.org/media/keys/ACCC4CF8.asc: sudo apt install curl ca-certificates gnupg curl https://www.postgresql.org/media/keys/ACCC4CF8.asc | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/apt.postgresql.org.gpg >/dev/null Create /etc/apt/sources.list.d/pgdg.list. The distributions are called codename-pgdg. In the example, replace buster with the actual distribution you are using. File contents: Let us know whether there is still anything unclear. Cheers - t
