Installer problem - lacking filesystem support

Hi everyone,

Trying to install and the partition manager is showing:

Unable to read the contents of this file system!
Because of this some operations may be unavailable.
The cause might be a missing software package.
The following list of software packages is required for fat32 file system support: dosfstools, mtools.

and similar for ext4 partitions. Any ideas?

Install dosfstools and e2fsprogs package. Though both should be in the installer by default.

Indeed, that is why I brought it to your attention. It seems there’s a problem if the installer lacks these tools. This is in the latest and previous builds:

nixos-graphical-19.09.1019.c5aabb0d603-x86_64-linux.iso
nixos-graphical-19.09.976.c75de8bc12c-x86_64-linux.iso

It’s suggests there might be other problems.

I’m a nixos nooby but have been using linux for decades

I think he means, you should be able to do nix-shell -p e2fsprogs -p dosfstools and you will have a shell with those available.

Although, it sounds like those should be included in the iso. I’m not familiar with the graphical iso
