I’ve just upgraded to
nix 2.1 with
nix upgrade-nix, and
nix-channel --update does not work anymore:
% nix-channel --update unpacking channels... error: unsupported builtin function 'buildenv' builder for '/nix/store/xyqcscjac7bndrb7ycwi374xy6qx0vhw-user-environment.drv' failed with exit code 1 error: build of '/nix/store/xyqcscjac7bndrb7ycwi374xy6qx0vhw-user-environment.drv' failed error: program '/nix/store/n7fvy0k555gwkkdszdkhi3h0aahca8h3-nix-2.1/bin/nix-env' failed with exit code 100
Is this a bug?
