Upgrade To Ubuntu 10.04 Lucid Lynx Without An Internet Connection Well, if you don't have an Internet connection, you can still upgrade to Ubuntu 10.04 Lucid Lynx, but you'll need to download the Ubuntu 10.04 Lucid Lynx alternate CD somehow. You can download the Ubuntu Alternate ISO from HERE . Then, you can then either write the Ubuntu 10.04 Lucid Lynx Alternate ISO onto a CD or simply mount the ISO image using the following command: $ sudo mount -o loop ubuntu-10.04-alternate-i386.iso /media/cdrom0 Give exact path to " ubuntu-10.04-alternate-i386.iso " if your are not in the directory where you have saved the alternate cd image. Once you insert the CD or mount the ISO image, a dialog should pop up offering you the option to upgrade using that CD / ISO image. If of any reason the pop up doesn't come, you can start the upgrade manually by typing the command below. $ gksu "sh /cdrom/cdromupgrade"

Many of us may know how to extract a .Tar.gz file. But how many of us know how to extract a .bz2, .lz, etc files. Some extra option to tar will do the needfull, but we will need to know the options for each type of archive. But no worries any more. You can now use ' unp ', a script that extract any type of archive by itself. To extract any archive just type: $ unp archive_file where " archive_file " can be a rar, zip, tar.gz, deb, tar.gz2, rpm or any other archive. The best thing is that you can use unp to extract multiple types of archives at the same time. example: $ unp *.tar *.tar.gz *.tar.bz *.rpm *.deb *.zip *.rar To extract all the archive files in the current directory: $ unp * Install unp $ sudo apt-get install unp
