I got the following error while using the sudo apt-get update
command.
>>> /etc/sudoers.d/90-cloudimg-ubuntu: syntax error near line 1 <<<
sudo: parse error in /etc/sudoers.d/90-cloudimg-ubuntu near line 1
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
I tried finding a solution, the end of the file is already
#includedir /etc/sudoers.d
You can view the output for pkexec visudo
in this screenshot
You can view the file etc/sudoers:
s file MUST be edited with the 'visudo' command as root.
#
Please consider adding local content in /etc/sudoers.d/ instead of
directly modifying this file.

See the man page for details on how to write a sudoers file.

See sudoers(5) for more information on "#include" directives:
includedir /etc/sudoers.d
and the file etc/sudoers.d/README
#
# As of Debian version 1.7.2p1-1, the default /etc/sudoers file created on
# installation of the package now includes the directive:
#
# #includedir /etc/sudoers.d
#
# This will cause sudo to read and parse any files in the /etc/sudoers.d
# directory that do not end in '~' or contain a '.' character.
#
# Note that there must be at least one file in the sudoers.d directory (this
# one will do), and all files in this directory should be mode 0440.
#
# Note also, that because sudoers contents can vary widely, no attempt is
# made to add this directive to existing sudoers files on upgrade. Feel free
# to add the above directive to the end of your /etc/sudoers file to enable
# this functionality for existing installations if you wish!
#
# Finally, please note that using the visudo command is the recommended way
# to update sudoers content, since it protects against many failure modes.
# See the man page for visudo for more information.

I want a specific and precised answer. I am new to Ubuntu (14.04), please help me!

First of all, never edit
/etc/sudoers
manually, always usevisudo
. Your problem was a syntax error in the file/etc/sudoers.d/90-cloudimg-ubuntu
but it is now a malformed/etc/sudoers
.So, to fix it (now that you have removed any changes you may have made), run
pkexec visudo
and make the file look like this:Save the file (Ctrl+O) and exit (Ctrl+X). Next, I suggest you just move the
/etc/sudoers.d/90-cloudimg-ubuntu
somewhere else so it doesn't cause issues:At this point, you should have a working
sudo
. If the90-cloudimg-ubuntu
file was necessary, ask a new question with the contents of that file an we can help you put it back and fix the error.
