title: Disadvantage of using --allow-releaseinfo-change for apt-get update
body: <p>Refering to this <a href="https://stackoverflow.com/questions/68802802/repository-http-security-debian-org-debian-security-buster-updates-inrelease">issue</a>, on Ubuntu 20.04, I know I could add a flag <em>--allow-releaseinfo-change update</em> to fix the issue when doing <em>apt-get update</em> but what would the cons be by using this flag? What would be the implication going forward? Does it introduce any security issue going forward?</p>
