Please tell us where the configuration recovery script is located. You need to change it so that it doesn’t change repositories or reset them to default configurations. Because the configuration goes mirrorlist=http://mirrorlist.netserver.org/?release=… but it is not available in Russia. In General.
I think this is a flaw, because why do I need to reset the configuration to default repositories, and not the ones that are registered in the recovery archive? It turns out that I change the repositories to those that are available in our country, and they are reset to default when restoring and the recovery immediately ends with an error.
I tested all the servers from the mirror:
