Recently I tried to update ubuntu software and I got the following error:
dpkg: error processing install-info (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: install-info
I think it had to do with a resent MySQL update I made. Any way, the only solution that worked for
me was:
sudo mv /var/lib/dpkg/info/install-info.postinst /var/lib/dpkg/info/install-info.postinst.bad
which seems a bit drastic. Oh well, it can be reversed:
sudo mv /var/lib/dpkg/info/install-info.postinst.bad /var/lib/dpkg/info/install-info.postinst

and update: Similar problem occurred to me when I updated to Ubuntu 16.04.
/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
This time I opened the etc/environment file, and by trial I commented the second line
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/mysql/server-5.6/bin" #source /etc/environment
It worked!
