  • Remove the 2 lines in the sources file that are the 2 errors in /etc/apt/sources.list – David Sep 29 '22 at 07:33
  • I updated question and add source.list to it.Which two lines do you mean? – samirapadidar Sep 29 '22 at 07:44
  • I assume you are using shecan.ir to bypass repos that are blocking iran ip addresses. I think this error is raised since those repos have apparently mitigated shecan's bypassing methods. – Jariani Jan 13 '23 at 08:56
  • In the meantime I advise against using google chrome since having non-updated google chrome can bear security risks. I assume you need the other repos for your work-related matters, I advise getting a europe vps and setting up proxy. – Jariani Jan 13 '23 at 08:59
  • Also sometimes simply switching to a different ISP solves this issue, for instance switch to mobile hotspot from wifi. – Jariani Jan 13 '23 at 09:11

There are two problems.

  1. You have added some repositories that doesn't exist or not working.

    https://dl.bintray.com/rabbitmq-erlang/debian focal https://packagecloud.io/rabbitmq/rabbitmq-server/ubuntu

It is set in some file(s) located in /etc/apt/sources.list.d directory.

  1. Google repository is temporary unavailable for some reason. You can try again later. The repository looks correct to me.

It is a bit weird that at the same time 3 repositories including the Google one don't respond.

It can also be a network issue.
