So, recently I was forced to change a debian package to install it during the installation of the DVD. So, basically all I need to do is to change the Priority level of the package in the “control file” from optional or standard to important and then edit the iso dvd.
NOTE: Check this to find how to you can edit an iso dvd.
1: Make directory, /home/edit-deb
2: Copy debian file to the directory. Lets say we have a debian file, sample.deb and we copy it to /home/edit-deb
3: Now, create one more directory (/home/edit-deb/sample)
4: Just go to /home/edit-deb
5: Extract debian package data using the following command.
dpkg-deb –extract sample.deb ./sample
6: Extract debian installer files (control, preinst, postinst, prerm, postrm etc)
dpkg-deb -e openssh-client_5.1p1-5_amd64.deb ./sample/DEBIAN
7: Now, you have extracted all the files in sample.deb. Make changes to files in /home/edit-deb/sample and /home/edit-deb/sample/DEBIAN.
8: Recreate the new debian backage after making changes by using the following commands.
mv sample.deb sample_backup.deb
dpkg-deb -b sample
9: Once you run all the above commands, now you should see the new sample.deb which is the newer version of the package.
