Name

nix profile upgrade - upgrade packages using their most recent flake

Synopsis

nix profile upgrade [option...] elements...

Examples

  • Upgrade all packages that were installed using a mutable flake reference:

    # nix profile upgrade '.*'

  • Upgrade a specific package:

    # nix profile upgrade packages.x86_64-linux.hello

  • Upgrade a specific profile element by number:

    # nix profile list
0 flake:nixpkgs#legacyPackages.x86_64-linux.spotify …

# nix profile upgrade 0

Description

This command upgrades a previously installed package in a Nix profile, by fetching and evaluating the latest version of the flake from which the package was installed.

Warning

This only works if you used a mutable flake reference at installation time, e.g. nixpkgs#hello. It does not work if you used an immutable flake reference (e.g. github:NixOS/nixpkgs/13d0c311e3ae923a00f734b43fd1d35b47d8943a#hello), since in that case the "latest version" is always the same.

Options

  • --profile path
    The profile to update.

Common evaluation options:

  • --arg name expr
    Pass the value expr as the argument name to Nix functions.

  • --argstr name string
    Pass the string string as the argument name to Nix functions.

  • --eval-store store-url
    The Nix store to use for evaluations.

  • --impure
    Allow access to mutable paths and repositories.

  • --include / -I path
    Add path to the list of locations used to look up <...> file names.

  • --override-flake original-ref resolved-ref
    Override the flake registries, redirecting original-ref to resolved-ref.

Common flake-related options:

  • --commit-lock-file
    Commit changes to the flake's lock file.

  • --inputs-from flake-url
    Use the inputs of the specified flake as registry entries.

  • --no-registries
    Don't allow lookups in the flake registries. This option is deprecated; use --no-use-registries.

  • --no-update-lock-file
    Do not allow any updates to the flake's lock file.

  • --no-write-lock-file
    Do not write the flake's newly generated lock file.

  • --override-input input-path flake-url
    Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file.

  • --recreate-lock-file
    Recreate the flake's lock file from scratch.

  • --update-input input-path
    Update a specific flake input (ignoring its previous entry in the lock file).

Options that change the interpretation of installables:

  • --derivation
    Operate on the store derivation rather than its outputs.

  • --expr expr
    Interpret installables as attribute paths relative to the Nix expression expr.

  • --file / -f file
    Interpret installables as attribute paths relative to the Nix expression stored in file.
