NB: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin.
E: Sub-process /usr/bin/dpkg returned an error code (2)

Try fix:

Edit /etc/sudoers with visudo and add the line:

Defaults        env_reset
Defaults    secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

The whole file now looks like this for me:

# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#

Defaults        env_reset
Defaults    secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL) ALL

# Allow members of group sudo to execute any command
# (Note that later entries override this, so you might need to move
# it further down)
%sudo ALL=(ALL) ALL
#
#includedir /etc/sudoers.d

droidzone ALL=(ALL) ALL

 

Trying the command which failed earlier:

[[email protected] ~]$sudo apt-get install emacs

emacs is already the newest version.
The following package was automatically installed and is no longer required:
xaw3dg
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 122 not upgraded.[/code]
It now works!
