Raspberry Pi OS • Re: Cannot "sudo apt update" after failed Postgresql install

Many thanks. Googled and there are tens of writings on that error message. Tried them one by one until the below one that 'partially' solved the issue

1. the file /etc/apt/sources.list.d/pgdg.list was renamed to /etc/apt/sources.list.d/old_pgdg.list. NOT SOLVED

2, use nano, add # to commend out the only one line in old_pgdg.list SOLVED
The one line in file is:
#deb [signed-by=/usr/share/postgresql-common/pgdg/apt.postgresql.org.asc] https://apt.postgresql.org/pub/repos/apt bookworm-pgdg main

3. Now I can issue update and it still try to get the PostgreSQL and reported no public key (and seem no harm now). Any idea if I should leave it as that or try to eliminate the warning but kind of afraid that I may mess it up

Is the message with "W" warning?

$ sudo apt update
