I am getting the following error message when installing Daedalus 2.0.
warning: the group ‘nixbld’ specified in ‘build-users-group’ does not exist
error: could not set permissions on ‘/home/user/.daedalus/nix/var/nix/profiles/per-user’ to 755: Operation not permitted
I had previous main-net version installed with no problems. Removed previous version but 2.0 will not install.
