[solved]sudo: effective uid is not 0 (trying build in chroot...)

Feeling like a beginner, so I am posting here.

I try to build an aur-package using a chroot environment_

[bernd_b@amd64-archlinux libavresample]$ makechrootpkg -c -r $CHROOT
==> Synchronizing chroot copy [/var/lib/archbuild/extra-x86_64/root] -> [bernd_b]...done

sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges?

sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges?
==> ERROR: 'pacman' failed to install missing dependencies.
==> Missing dependencies:
  -> git
  -> nasm
==> ERROR: Could not resolve all dependencies.
==> ERROR: Build failed, check /var/lib/archbuild/extra-x86_64/bernd_b/build

Since all aur-helper and

[bernd_b@amd64-archlinux libavresample]$ sudo pacman --help
usage:  pacman <operation> [...]
operations:
    pacman {-h --help}
    pacman {-V --version}
    pacman {-D --database} <options> <package(s)>
    pacman {-F --files}    [options] [package(s)]
    pacman {-Q --query}    [options] [package(s)]
    pacman {-R --remove}   [options] <package(s)>
    pacman {-S --sync}     [options] [package(s)]
    pacman {-T --deptest}  [options] [package(s)]
    pacman {-U --upgrade}  [options] <file(s)>

use 'pacman {-h --help}' with an operation for available options

work like charm, I don't get the meaning of

"sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the 'nosuid' option set or an NFS file system without root privileges?
==> ERROR: 'pacman' failed to install missing dependencies."

Ok, stupid me.

I had the option "users" in my mount option for the xfs file system, where the chroot environment is placed. This seemed to set the "nosuid" option as well.

Remounting the file system without the user option makes everything working as expected.

Faced a similar issue so I figured I might drop the solution here since it's the first google result.

At the end I figured out that the issue was related to namespaces.
You have two solutions, either use su -mm before chrooting into the environment or enable global namespaces in your root manager(presumably magisk)

Strike #2. Please don't necrobump. It doesn't look like you're even using Arch, so this information isn't even relevant...

Closing.
