+Do not remove this patch unless you know what you are doing!
+
+We don't have module "packaging" packaged and thus cannot use it without
+installing through "pip". But for stable packages we cannot use it in
+postinst script to add missing dependencies.
+
+So if you decide to drop this patch:
+* Add python3-packaging to termux-packages.
+* Alternatively: create a postinst deb script (pip3 install packaging)
+  and move borgbackup to https://github.com/termux/unstable-packages
