+===== apt fastest mirror =====
+apt-get now supports a 'mirror' method that will automatically select a good mirror based on your location. Adding the following at the top of ''/etc/apt/sources.list'' file will pick the best mirror:
+Follow this with:
+<code>vi /etc/apt/sources.list</code>
+Adjust for the appropriate ubuntu distribution.
+<code>
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal main restricted universe multiverse
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal-updates main restricted universe multiverse
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal-backports main restricted universe multiverse
+deb mirror://mirrors.ubuntu.com/mirrors.txt focal-security main restricted universe multiverse
+</code>
+Do an update for apt to get/select the best mirror before any installs:
+<code>apt-get update</code>
