If you are not connected to internet, then still you can install packages
from Debian Installer ISOs.
from Debian Installer ISOs.
For example, if Debian 7.0 (Wheezy) ISOs are in directory /media/FreeAgent GoFlex Drive/Softwares/Debian_7.0_Wheezy
directory and we want to mount these iso in /mnt/Debian/ directory. The following command can be used:
$ sudo $(which mount_debian.pl) -d /mnt/Debian -g -r "/media/FreeAgent GoFlex Drive/Softwares/Debian_7.0_Wheezy" Using iso(s) dir '/media/FreeAgent GoFlex Drive/Softwares/Debian_7.0_Wheezy' Using mount point dir '/mnt/Debian' ... Total 11 iso(s) mounted successfully.
Unmounting of the iso(s) can be achieved by the following command:
$ sudo $(which mount_debian.pl) -d /mnt/Debian -u -g -r Running: umount "/mnt/Debian"/*.iso Running: rmdir "/mnt/Debian"/*.iso Running: cp "/etc/apt/sources.list.net" "/etc/apt/sources.list" Running: apt-get update ...
Usage of the command:
$ sudo $(which mount_debian.pl)
/home/mitesh/Perl/mount_debian.pl: Please provide Dir where Debian installer iso(s) are present.
USAGE: /home/mitesh/Perl/mount_debian.pl [options] iso_dir
-a apt_sources_dir default /etc/apt
-d mount_base_dir default /mnt/Debian
-g debug on
-r apt-get update
-u unmount
iso_dir Dir where Debian installer iso(s) are present.
PS: iso_dir is not required with -u command
The mount_debian.sh perl script is given as follows:
