I did a quick search around this issue but I couldn't find anything helpful. Any Nix hacker out there to help?

I would like to avoid a reinstall, even though that's super easy ;).

UPDATE

I couldn't wait! O:)

I went ahead and removed the current installation...and when I do a fresh install I basically got the same result:

Cloning builder process: Operation not permitted when using Nix (under Linux) update channel

I use Arch Linux 4.19.15-1-lts #1 SMP Sun Jan 13 13:53:52 CET 2019 x86_64 GNU/Linux. I do also have Nix installed: nix-env (Nix) 2.2.

I've never had any problems until the recent update to version 2.2. I always do the upgrades/updates with these two steps:

$ nix-channel --update
...
$ nix-env --upgrade
...

...but after the recent 2.2 update I can't find a way to make nix-channel --update work anymore. I'm always getting these errors:

error: cloning builder process: Operation not permitted
error: unable to start build process
error: program '/nix/store/876x7a35qbn3q062b6zcz6va88m0990d-nix-2.2/bin/nix-env' failed with exit code 1

...even if I do rollback the previous operation(s):

$ nix-channel --update 
unpacking channels...
error: cloning builder process: Operation not permitted
error: unable to start build process
error: program '/nix/store/876x7a35qbn3q062b6zcz6va88m0990d-nix-2.2/bin/nix-env' failed with exit code 1
$ nix-channel --rollback 
switching from generation 40 to 39
$ nix-channel --update 
unpacking channels...
error: cloning builder process: Operation not permitted

error: program '/nix/store/876x7a35qbn3q062b6zcz6va88m0990d-nix-2.2/bin/nix-env' failed with exit code 1

This is what I have in the update list:

$ nix-channel --list 
nixpkgs https://nixos.org/channels/nixpkgs-unstable

...and eventually I can't even delete that:

$ nix-channel --remove nixpkgs 
uninstalling 'nixpkgs-19.03pre165281.7d864c6bd63'
error: cloning builder process: Operation not permitted

error: program '/nix/store/876x7a35qbn3q062b6zcz6va88m0990d-nix-2.2/bin/nix-env' failed with exit code 1

I did a quick search around this issue but I couldn't find anything helpful. Any Nix hacker out there to help?

I would like to avoid a reinstall, even though that's super easy ;)
