I tried to install manjaro qonos and set label for all the partitions, also for efi partition, during installation it throws the error:
I got an error installing, it says ˋcommand : fatlabel/dev/nvme1np1 Efi partition ˋwhat’s wrong?
Afterwards i installed without giving the efi partition a label and it worked.
Possibly you set a LABEL that’s not supported on FAT/VFAT/exFAT? If I recall, then it does not support certain characters, and the LABEL can only be 14 characters long.
Anyway, it’s not important. By default, your EFI partition will be listed in /etc/fstab with its UUID anyway.
