In the past, if you used Vagrant to install an Ubuntu virtual machine locally, you first needed to replace the apt source, such as Alibaba source, Tencent source, Tsinghua source, etc. After checking the /etc/apt/sources.list file, Huawei was used directly by default. The source is very fast in terms of speed. As you can see above, the average download speed reaches 1.56MB/s.
