This is the error message I get when I do a sudo apt upgrade. The upgrade fails and includes this message:

Setting up install-info (6.1.0.dfsg.1-5) ...
/usr/sbin/update-info-dir: 2: /etc/environment: source: not found
dpkg: error processing package install-info (--configure):
subprocess installed post-installation script returned error exit 
status 127
Errors were encountered while processing:
 install-info
E: Sub-process /usr/bin/dpkg returned an error code (1)

I reinstalled install-info through synaptic and am still getting this error and would be grateful for help in setting me straight as to how to read this message and how to react..

  • Can someone help me to read this error message? It seems to be saying /etc/environment is missing something? It's simply a line of path statements. – Tom Connolly May 11 '18 at 19:06
  • Looking at the error, it seems there is a command in the script /usr/sbin/update-info-dir that says source /etc/environment, but it is being run by a shell (dash I guess) that doesn't know the source command. Instead of source, that script should have . /etc/environment, which does the same thing. That's very very strange. Here's the version of that file I have on my system – Zanna May 16 '18 at 07:48

I found this way down in a thread elsewhere, and it worked!

if all else fails. What I did was I first changed the directory to:

cd /var/lib/dpkg/info

then I removed everything with .postinst:

sudo rm *.postinst

then update repositories

sudo apt-get update

then everything went back to normal when I did:

sudo apt-get --force-yes install openjdk-7-jre-headless

Note: I did not do this last line, as my issue didn't have anything to do with openjdk. I simply ran the apt update

  • Another option is to edit the offending .postinst file and put exit 0 on the second line (after the first line containing #!/bin/sh. – WinEunuuchs2Unix May 12 '18 at 18:21

I started to get same thing and just used

for i in $(ls -F *.postinst); do mv ./$i ./$i.old; done in /var/lib/dpkg/info

then my standard ansible playbooks to bring servers current worked
