I followed the guideline in Use APT repositories - Percona Server for MySQL and tried to install percona in my VM (ubuntu18.04, Linux version 5.10.9). However, I failed when calling ‘sudo percona-release setup ps80’.
It looks like your proxy is rejecting requests to 80 port but at the same time you mentioned that apt command is working.
Could you provide an output of apt update command?
Moreover, I tested another server without proxy, it works fine. So I feel the problem may come from proxy settings. Could you suggest some ways to fix the problem? Many thanks
Thus it seems that ‘percona-release setup ps80’ only fetches some necessary debs for me, and downloading debs manually does not affect the following steps.
