I have an issue with dpkg and install-info. I cannot add any new packages without encountering a couple errors:

   Setting up install-info (6.5.0.dfsg.1-2) ...
/usr/sbin/update-info-dir: 3: /etc/environment: source: not found
dpkg: error processing package install-info (--configure):
 installed install-info package post-installation script subprocess returned error exit status 127
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

Clearly there is an issue with /etc/environment.

I have tried solutions from:

I have also reinstalled and purged/reinstalled install-info. I have checked the paths for /etc/environments and they conform to the first url above.

Any help appreciated & Thanks John


After some further digging. The java on this system is messed up after having issues with Ubiquiti's controller after upgrade from 16.04 to 18.04. Removing java references from /etc/environment did the trick.

What my etc/environment looked like before:

JAVA_HOME="/usr/lib/jvm/java-8-oracle" source /etc/environment

Fixed Version:
