The installation command (slightly different in 2021) on the homebrew site did not work for the same reason you posted.
#Brew install wget error macos sierra manual#
If you want to learn what a particular command and its various arguments do, try checking the manual first by typing man + the command you want information on ( man sudo or man chown for example). There are some safeguards provided by the more recent Mac operating systems with System Integrity Protection (SIP) but you can still wreak plenty of havoc on your system. Only run commands in your terminal if you understand the command and know exactly what it will do when passed a given set of options/arguments. If you see the majority are owned by another user (your own username for instance), the problem is far more extensive than your sudoers file.Īs a general point, you need to be very careful running any command prefaced by sudo. By default, pretty much every file in the /etc/ directory is meant to be owned by root (an obvious one is /etc/passwd). The third column in from the left shows the user who owns a given file. Run ls -l /etc/ and examine the output of that command. You can run sudo ls for instance in a new shell if the contents of the current directory are listed and you don't see that ownership error above then all is well.Īlthough this falls outside the bounds of your question, I'm concerned that if you've unwittingly changed ownership of the sudoers file while attempting to change ownership of /usr/local/ you may have done this to other important files as well. You should now be able to use the sudo command again with your regular admin user.
#Brew install wget error macos sierra password#
Open Terminal and switch to the root user by typing su - and entering the password you assigned to your root user account in step 1.Īs the root user, change ownership of the sudoers file back to root and the wheel group with the following: chown root:wheel /etc/passwdįollow the instructions in step 1 again but this time disable the root user again.Enable the root user using Apple's instructions here (under the section 'Enable or disable the root user').Because you've changed ownership of the sudoers file you probably won't be able to sudo yourself out of trouble as the sudo command won't run for security reasons if the sudoers file from which it draws its configuration is owned by a user other than root (this is why homebrew is spitting out the last error message above). The chown command you've been using above changes the ownership of files from one user and/or group to another. The sudoers file denotes which users and groups are allowed to escalate to a root privilege set by prefacing a command with sudo and typing their login password. At some point you may have accidentally changed this, perhaps by mistyping a command. The warning at the end is telling you that the root user (denoted by default with the uid 0) doesn't own the /etc/sudoers file anymore. Sudo: no valid sudoers sources found, quittingĬan some one let me know what does the last set of warnings / errors denote? Can these be ignored? Sudo: /etc/sudoers is owned by uid 504, should be 0
#Brew install wget error macos sierra how to#
Read the analytics documentation (and how to opt-out) here: => Homebrew has enabled anonymous aggregate user behaviour analytics. Now it is showing me the below logs in console. It gave me some Operation not permitted warnings. I executed the below command as suggested above sudo chown -R $(whoami) $(brew -prefix)/* sudo chown -R $USER:admin /usr/localīut it did not work because of the issue discussed here. Then I tried executing the command as suggested in the above issue. I tried to install homebrew again by executing the below command /usr/bin/ruby -e "$(curl -fsSL )"īut the installation failed with the error as discussed here. So I uninstalled the homebrew by executing the below command ruby -e "$(curl -fsSL )"
#Brew install wget error macos sierra upgrade#
After upgrade my homebrew seems to have stopped working. Recently I upgraded to MacOS High Sierra (10.13.4).
