I. Update the source and change the source server

Sudo apt-Get install *** is often used in Ubuntu,

But sometimes there may be various errors. If there is no command error, it may be a problem with the software source!

First, you can enter sudo apt-Get update to update the source, and then try again.

It may also be that the connection is not connected to the source, or sometimes the source may be used very slowly. For example, after Ubuntu is installed, the initial source is a foreign source server, at this time, you can configure the source server-I found today that the source can be configured, cainiao!
