Known issues: - CVE-2020-25031 You can install it anyway by allowing this package, using the following methods: a) To temporarily allow all insecure packages, you can use an environment variable for a single invocation of the nix tools: $ export NIXPKGS_ALLOW_INSECURE=1 Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake, then pass `--impure` in order to allow use of environment variables. b) for `nixos-rebuild` you can add ‘checkinstall-1.6.2’ to `nixpkgs.config.permittedInsecurePackages` in the configuration.nix, like so: { nixpkgs.config.permittedInsecurePackages = [ "checkinstall-1.6.2" ]; } c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add ‘checkinstall-1.6.2’ to `permittedInsecurePackages` in ~/.config/nixpkgs/config.nix, like so: { permittedInsecurePackages = [ "checkinstall-1.6.2" ]; } GC Warning: Failed to expand heap by 4194304 KiB GC Warning: Failed to expand heap by 4194304 KiB GC Warning: Failed to expand heap by 4194304 KiB GC Warning: Failed to expand heap by 4194304 KiB error: … while evaluating attribute 'drv' at /nix/store/kwli1syc3yhl69wcl9690i8gwbawsj8x-filnix-experiment-0.13.3/lib/experiment/planner.nix:14:3: 13| { 14| drv = p.drvPath; | ^ 15| name = p.name; … while evaluating the attribute 'drvPath' at /nix/store/nwvpfag9bxa929fkn4s5igg0nbzwnivj-source/lib/customisation.nix:418:7: 417| // { 418| drvPath = | ^ 419| assert condition; (stack trace truncated; use '--show-trace' to show the full, detailed trace) error: Package ‘totem-43.1’ in /nix/store/nwvpfag9bxa929fkn4s5igg0nbzwnivj-source/pkgs/by-name/to/totem/package.nix:114 is marked as broken, refusing to evaluate. a) To temporarily allow broken packages, you can use an environment variable for a single invocation of the nix tools. $ export NIXPKGS_ALLOW_BROKEN=1 Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake, then pass `--impure` in order to allow use of environment variables. b) For `nixos-rebuild` you can set { nixpkgs.config.allowBroken = true; } in configuration.nix to override this. c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add { allowBroken = true; } to ~/.config/nixpkgs/config.nix.
