Hi Rickard,

can you run strace -o /tmp/file -f nix-env -i ...

If the Nix daemon is used this trace file should not contain any access
to default.lock (my nix-env run didn't contain this line)

So if it does double check that NIX_REMOTE=daemon is exported

This just worked for me in the past. So I may be mistaken.

Also ensure that the directory
/nix/var/nix/profiles exists.
