package install-info 4.13a.dfsg.1-6ubuntu3 failed to install/upgrade: le sous-processus script post-installation installé a retourné une erreur de sortie d'état 127

Binary package hint: texinfo

During upgrade from 10.10 to 11.04 I got this message saying install-info package can't install. Then after reboot everything seems okay and when I try to update the system it stops with a message saying there is a problem with install-info.

You seem to have a syntax error in your /etc/environment file. You'll need to resolve this issue manually.
