remediate_allowlist = allow_attr: rebuild_amendment: ''
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.
${rebuild_amendment}
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allow${allow_attr} = true; }
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
${flakeNote}
b) for `nixos-rebuild` you can add ‘${getNameWithVersion attrs}’ to
`nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
like so:
{
nixpkgs.config.permittedInsecurePackages = [
"${getNameWithVersion attrs}"
];
}
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
‘${getNameWithVersion attrs}’ to `permittedInsecurePackages` in
~/.config/nixpkgs/config.nix, like so:
{
permittedInsecurePackages = [
"${getNameWithVersion attrs}"
];
}
'';
