Ubuntu uses the installation CD as the apt-get software update source.

If a problem occurs on the official website, use the Unbuntu8.10 disc as the apt-get Source. The steps are as follows: 1. Insert the disc into the cdrom and execute the sudoapt-cdromident command (do not do this ). It only scans, checks whether the content of the installation disc is complete, performs MD5 verification, and recognizes the optical disc label. 2. input sudoapt-cdromadd to officially import the disc source.

If a problem occurs on the official website, you can use the Unbuntu8.10 disc as the apt-get source.

The procedure is as follows:

1. Insert the CD into the cdrom and run the sudo apt-cdromident command (do not do this ). It only scans, checks whether the content of the installation disc is complete, performs MD5 verification, and recognizes the optical disk label.

2. enter sudo apt-cdrom add to write the disc source to/etc/apt/sources. list.

3. now, the disc source has been set up. you can see that there are more such items at the beginning of sources. list.

4. ubuntu 8.04 and 8.10 adopt the default installation method.
8.04 by default, gcc is not installed. 8.10 gcc is available, but things are incomplete. for example, there is no libstdc ++ 6-4.3-devg ++-4.3.
Some people say that if you connect to the Internet, sudo apt-get install build-essential is all set up.

5. install vmware-tools on ubuntu. (Although it is easy to connect to the Internet of virtual machines, the NAT method must be connected.) installation of vmware-tools fails, basically because build-essential is not fully installed.

Apt-get install openssh-server openssh-client

6. complete.
