[Nix-dev] Fwd: Cannot upgrade old NixOS

Yes, something like a year.

Thanks, this command didn't fail and downloaded new packages. BUT new package
binaries are NOT RUNNABLE. Bash says that. So now I have runnable (but
old) nix-env
in one shell, and not runnable in all new shell tabs. The problem is
not only with
nix-env, perl is not runnable also.

old runnable nix-env hosts in `/run/current-system/sw/bin/nix-env`
new nix-env hosts in `/nix/var/nix/profiles/default/bin/nix-env`
