This is a simple shell script to convert a Debian Stretch HexChat package to a Jessie-compatible one. The stretch package is backwards-compatible with Jessie, but a dependency must be renamed for the package to install. The script provided here automates the process.
- This is a shell script, so a suitable shell is required to run it.
- dpkg-deb for extracting and re-creating the package.
- sed for replacing dependencies within the Debian dependency control file.
- Standard commands: cat, mv, echo
-
Download the script: convert_hexchat_stretch_to_jessie.sh (You will need to click the "Raw" button to actually download it!)
-
Download hexchat from here: https://packages.debian.org/stretch/hexchat
-
Change
OLD_PKGandNEW_PKGto match the Debian package file name from the packages site. I recommend that NEW_PKG be slightly different, e.g.old_first_part_JESSIE.deb. -
Run the script. You should now have a modified package.
-
Download hexchat-common from here: https://packages.debian.org/stretch/hexchat-common
-
Install the hexchat-common Debian package.
-
Install the new, modified hexchat Debian package. Done!
This script basically changes the libproxy1v5 dependency in Debian stretch's hexchat to simply libproxy1, which is the same library in Debian jessie, but under a different name.
When the package is extracted with dpkg-deb, the script will modify the extracted DEBIAN/control file and replace the libproxy1v5 dependency with jessie-compatible libproxy1 dependency.
Once done, it simply re-builds the package from the extracted (and now modified) directory.
