I’m trying to install some packages on Ubuntu 5.10 using the apt-get application unfortunately I always got this error message.

Media change: please insert the disc labeled
‘Ubuntu 5.10 _Breezy Badger_ - Preview i386 (20050908)’
in the drive ‘/cdrom/’ and press enter

I found a solution on this by browsing the internet. The problem is the apt-get application was checking for the installer in the cd-rom. In order to solve this, you need to edit the /etc/apt/sources.list. You need to comment out the first line with deb cdrom. Here is the sample entry…

#deb cdrom:[Ubuntu 5.10 _Breezy Badger_ - Release i386 (20051012)]/ breezy main
restricted

## Major bug fix updates produced after the final release of the
## distribution.

I checked my Firefox browser and I found out that the version of my firefox is 1.0.7 which is far old than the latest version (1.5.0.2).

I surfed the internet and found this wiki that help me in upgrading my firefox browser to the latest version.
