i run like this:

prod:~$ sudo visudo

and then i added myusername here

# User privilege specification
root    ALL=(ALL:ALL) ALL

i tried this also:

sudo sh -c 'echo "foobar ALL=(ALL) NOPASSWD:ALL" > /etc/sudoers.d/90-foobar'

then i tried to run apt-get update got this:

Reading package lists... Done
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
W: Problem unlinking the file /var/cache/apt/pkgcache.bin - RemoveCaches (13: Permission denied)
W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - RemoveCaches (13: Permission denied)

    "no password" does not mean "no sudo" - you still need to prefix the command with sudo, you just don't get asked for a password after – steeldriver May 22 at 22:39
  • It was too explain why you have to type in sudo. You cannot run the commands without sudo unless you switch to root. – Terrance May 22 at 22:59

    @steeldriver Would you like to post an answer? – Kulfy yesterday

It is not possible to run all commands, for which you do not have privileges, without sudo.
Solutions how to execute commands without sudo are:

  1. Became root: sudo su -
  2. Use acl for specific files or folders
    sudo setfacl -Rm u:your_username:rwx /var/lib/apt/lists/
    sudo setfacl -Rm u:your_username:rwx /var/cache/apt/

It is not safe to be an administrator all the time at your machine.
