Description
After installing Arch Linux 6.14.4-arch1-2 (2025.05.01) using the latest version of the archinstall guided script, I encountered an issue where the newly created user is not able to use sudo, even though I explicitly selected the option to allow the user to use sudo during the setup.
Steps Taken During Install
Used the guided installer (archinstall).
Chose btrfs, systemd-boot, minimal profile, and pipewire.
During the user setup:
Created a new user.
Set the password and confirmed it.
Checked the option: “User can use sudo”.
Completed the installation successfully.
Observed Behavior
After logging into the TTY with the newly created user and attempting a sudo command:
$ sudo vim /etc/pacman.conf
[sudo] password for user:
user is not in the sudoers file. This incident will be reported.Additional Notes
sudo is installed on the system , i always chroot after install to change fstab relatime to noatime , it did work on chroot i was able to use sudo and install vim and edit fstab , its when i remove my usb and boot into the os and try to use sudo the error pops user is not in the sudoers file
There is a new "group" field next to the username in the user creation step of archinstall, but it remains empty, even when "User can use sudo" is selected.
I suspect the installer is failing to add the user to the wheel group, which is necessary for sudo access when using the default sudoers configuration.
Expected behavior: Selecting “User can use sudo” should automatically add the user to the wheel group.
Expected Result
The user should be a member of the wheel group and added to sudoers file.
The sudoers file should allow wheel group members to execute commands via sudo.
