error [install basepkgs][255]
with this error :
[install basepkgs][255] ==> Creating install root at /mnt --install_base()
I guess the problem actually comes from the branch: destination Branch (root) different from the branch of the installer :
in install_base() function we call : setup_profiles()
setup_profiles() use pacman -Sy --noconfirm manjaro-iso-profile
(installer branch) but if my root branch is different we use after basetrap and somes packages are not found (Normal because it is another branch)
use only one mirror: https://mirror.netzspielplatz.de/manjaro/packages/
