netplan.io

The package "netplan.io" depends on "pandoc" and "pandoc" is pretty difficult to build.

Currently, our approach is to patch "netplan.io" removing the dependency.

Problem

There is a patch which works OK for jammy and netplan-0.105. It fails for netplan-0.106:

+ sudo chroot build-jammy-i386/rootfs bash -c 'cd '\''/src/netplan.io/netplan.io-0.106.1'\'' && patch -p1'

Create a fresh patch

• Create a folder for the original files
  • patches/jammy/prepare-netplan-patch/orig/debian
• Copy the original files into patches/jammy/prepare-netplan-patch/orig
  • mv patches/jammy/netplan.io patches/jammy/netplan.io-deactivated
  • ./build.sh -a i386 -o jammy netplan.io
  • cp build-jammy-i386/rootfs/src/netplan.io/netplan.io-0.106.1/Makefile patches/jammy/prepare-netplan-patch/orig/.
  • cp build-jammy-i386/rootfs/src/netplan.io/netplan.io-0.106.1/debian/control patches/jammy/prepare-netplan-patch/orig/debian/.
  • mv patches/jammy/netplan.io-deactivated patches/jammy/netplan.io
• Create a folder for the modified files
  • cp -a patches/jammy/prepare-netplan-patch/orig patches/jammy/prepare-netplan-patch/no-pandoc
• Apply the old patch
  • cat patches/jammy/netplan.io/netplan.io-0.105_no-pandoc.diff | ( cd patches/jammy/prepare-netplan-patch/no-pandoc; patch -f -p1 )
  • Lots of errors - most can be ignored
  • Look for files ending with ".rej"
• Makefile
  • Look at Makefile and Makefile.rej
  • easy fix!
• debian/control
  • Look at debian/control and debian/control.rej
  • easy fix!
• Delete working files
  • rm patches/jammy/prepare-netplan-patch/no-pandoc/{Makefile~,Makefile.*,debian/control~,debian/control.*}
• Create new patch: ( cd patches/jammy/prepare-netplan-patch; diff -ur orig no-pandoc ) >patches/jammy/netplan.io/netplan.io-0.106.1_no-pandoc.diff
• Deactivate old patch: git mv patches/jammy/netplan.io/netplan.io-0.105_no-pandoc.diff patches/jammy/netplan.io/netplan.io-0.105_no-pandoc.diff.deactivated
