Undecimus: Launch Daemon Controller’ (launchctl) update is causing ‘Sub-process /usr/libexec/cydia/cydo returned an error code (2)’ and ‘Unable to repair system’

[Sekkio]

The Launch Daemon Controller’ (launchctl) update is causing ‘Sub-process /usr/libexec/cydia/cydo returned an error code (2)’ in cydia when installing/uninstalling tweaks.

Unc0ver app shows the message ‘Unable to repair system’ when jailbreaking with the log mentioning:
dpkg: warning: 'launchctl' not found in PATH or not executable
dpkg: error: 1 expected program not found in PATH or not executable
Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin
E: Sub-process /usr/bin/dpkg returned an error code (2)

The problem persists after restoring rootFS and updating essential packages because cydia requires you to install essential packages including the bugged ‘Launch Daemon Controller’ (launchctl) update.

The workaround to this problem is to forcibly install Launch Daemon Controller’ (launchctl) via terminal or ssh with dpkg --force-all -i launchctl_22-1_iphoneos-arm.deb

Instructions to workaround:
Download https://apt.bingner.com/debs/1443.00/launchctl_22-1_iphoneos-arm.deb to filza
Open terminal (or ssh) and enter:
su
cd var/mobile/Documents
dpkg --force-all -i launchctl_22-1_iphoneos-arm.deb

To Reproduce
Steps to reproduce the behavior:

1. Update essential tweaks
