When I try to install any application without the support of Canonical, the software center said that "You have a problems with internet connection" or "Requires installation of untrusted packages" and does not let me to install

For this reason, I am afraid to reinstall the system, because after reinstalling, I would not be able to download the necessary application to me

Please help me as soon as possible!!!
