Install applications from CD

Asked by Sergio

Hi

By mistake I lost the network manager application on my ubuntu 11.04 32 bit PC. Obviously I cant install it from internet without the network manager. I download 11.04 version with anothe r machine an prepare a distribution CD then try to add this cd as a repository with both software center and application manager but its imposible to recobnize the cd, the application tells me that I must use apt-cdrom from the terminal to make the cd available but it dosesent works. I think that the problem is in the configuration files of /etc/apt but cant define exactly wath to do.

Any sugestion. Thanks for the help.

You can use software centre to enable the CD as a source. You can then install from the CD. If your wireless works in the liveCD desktop you can boot to that and update network manager. You can then copy the debs to the internal drive and install that way. Both ways are fine. Alternatively you could connect to a wired interface and run:

sudo dhclient3 eth0

Then run updates and install network manager as you wish (or wicd is an alternative)

Haha even easier :). You can now add the network manager app. If you use a wired connection all the time and have o interest in wireless, you can keep network manager off your system and use /etc/network/interfaces to define networking. This will make your OS run lighter and quicker as network manager will not need to be started or running to get networking running. If you use a static IP, it will make OS boot slightly faster as the boot process waits for DHCP to pass. Glad you got the gold
