invoke-rc.d missing --skip-systemd-native (Ubuntu Bionic)

[farmorg]

Good morning

Now that I've got the build working, the install fails with the following error:

Unpacking ngcp-rtpengine-utils (8.0.0.0+0mr8.0.0.0) ...
Setting up ngcp-rtpengine-daemon (8.0.0.0+0mr8.0.0.0) ...
invoke-rc.d: syntax error: unknown option "--skip-systemd-native"
dpkg: error processing package ngcp-rtpengine-daemon (--install):
installed ngcp-rtpengine-daemon package post-installation script subprocess returned error exit status 1

This happens for all of the various .deb packages.

Google suggests that the --skip-systemd-native option was removed from upstream Debian.

I have tried editing the source code to remove all of the --skip-systemd-native entries and also in the install files in /var/lib/dpkg/info/ngcp* but weirdly they seem to reappear in the install files when I run dpkg-buildpackage.

The resulting package states:

dpkg -l | grep -i ngcp
iU ngcp-rtpengine 8.0.0.0+0mr8.0.0.0 all NGCP RTP/media proxy - meta package
iF ngcp-rtpengine-daemon 8.0.0.0+0mr8.0.0.0 amd64 proxy for RTP and media streams used in NGCP, userspace part
ii ngcp-rtpengine-iptables 8.0.0.0+0mr8.0.0.0 amd64 IPtables extension module for the kernel-space NGCP media proxy
ii ngcp-rtpengine-kernel-dkms 8.0.0.0+0mr8.0.0.0 all IPtables kernel module for the NGCP media proxy - DKMS
ii ngcp-rtpengine-kernel-source 8.0.0.0+0mr8.0.0.0 all IPtables kernel module for the NGCP media proxy - source
iF ngcp-rtpengine-recording-daemon 8.0.0.0+0mr8.0.0.0 amd64 recording daemon for RTP and media streams
ii ngcp-rtpengine-utils 8.0.0.0+0~mr8.0.0.0 all scripts and Perl modules for NGCP rtpengine

Have you tried with init-system-helpers from Bionic backports?

[farmorg]

Thankyou, that solved it.

I had the same problem, solved it by adding the file /etc/apt/preferences.d/init-system-helpers with the content:

Package: init-system-helpers
Pin: release a=bionic-backports
Pin-Priority: 500

And then an update installed the required package.

This also works well in cloud-init with package_upgrade: true - the upgrade process updates init-system-helpers, then when the packages module installs RTPEngine, everything is already prepared.

sudo apt-get install init-system-helpers
sudo apt update
