Error while installation manjaro kde plasma

Hi, when I try to install manjaro the installation programm throws an error:

<class 'OSError'>
[Errno 30] Read-only file system: '/tmp/calamares-root-hn3xad2b/etc/locale.conf'

Traceback:
File "/usr/lib/calamares/modules/localecfg/main.py", line 158, in run
    with open(target_locale_conf_path, "w") as lcf

I also tried to run the installation from cli with root permissons and this was the output:

    ~  sudo calamares                                                                                                                                                                            ✔  4m 58s 
