Good afternoon, please tell me what I'm doing wrong. I just installed the Linux Ubuntu on my computer and still don’t understand anything about it. I tried to install PostreSQL and pgAdmin. I installed on this video tutorial https://www.youtube.com/watch?v=Vdzb7JTPnGk I get this error.
Text of Error: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'http://apt.postgresql.org/pub/repos/apt focal-pgdg InRelease' doesn't support architecture 'i386'
Tell me please how to fix it.My version of ubuntu: Ubuntu 20.04 LTS
