|

a) To temporarily allow ${remediation_phrase allow_attr}, you can use an environment variable

for a single invocation of the nix tools.
|

$ export ${remediation_env_var allow_attr}=1
|

${flakeNote}
|

b) For `nixos-rebuild` you can set

{ nixpkgs.config.allow${allow_attr} = true; }
|
||||
in configuration.nix to override this.
|
||||
${rebuild_amendment attrs}
|
||||
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
|

|

to ~/.config/nixpkgs/config.nix.

|

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
|
||||
${flakeNote}
|
||||
b) for `nixos-rebuild` you can add ‘${getName attrs}’ to
|
||||
`nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
|
||||
like so:
|
||||
|
||||
{

nixpkgs.config.permittedInsecurePackages = [
|
||||
"${getName attrs}"
|
||||
];
|

}
|
||||
|
||||
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
|
||||
‘${getName attrs}’ to `permittedInsecurePackages` in
|
||||
~/.config/nixpkgs/config.nix, like so:
|
||||
|
||||
{
|

permittedInsecurePackages = [
|

"${getName attrs}"
