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 an unlocked flake reference:
# nix profile upgrade --all
  • Upgrade a specific package by name:
# nix profile upgrade hello
  • Upgrade all packages that include ‘vim' in their name:
# nix profile upgrade --regex '.*vim.*'

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 an unlocked flake reference at installation time, e.g. nixpkgs#hello. It does not work if you used a locked flake reference (e.g. github:NixOS/nixpkgs/13d0c311e3ae923a00f734b43fd1d35b47d8943a#hello), since in that case the “latest version” is always the same.

Options

  • --all Match all packages in the profile.
  • --profile path The profile to operate on.
  • --regex pattern A regular expression to match one or more packages in the profile.

Common evaluation options

  • --arg name expr Pass the value expr as the argument name to Nix functions.
  • --arg-from-file name path Pass the contents of file path as the argument name to Nix functions.
  • --arg-from-stdin name Pass the contents of stdin as the argument name to Nix functions.
  • --argstr name string Pass the string string as the argument name to Nix functions.
  • --debugger Start an interactive environment if evaluation fails.
  • --eval-store store-url The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.
  • --impure Allow access to mutable paths and repositories.
  • --include / -I path Add path to search path entries used to resolve lookup paths This option may be given multiple times. Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable.
  • --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.

    DEPRECATED

    Use --no-use-registries instead.

  • --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.
  • --output-lock-file flake-lock-path Write the given lock file instead of flake.lock within the top-level flake.
  • --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.

    DEPRECATED

    Use nix flake update instead.

  • --reference-lock-file flake-lock-path Read the given lock file instead of flake.lock within the top-level flake.

  • --update-input input-path

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

    DEPRECATED

    Use nix flake update instead.

Logging-related options

  • --debug Set the logging verbosity level to ‘debug'.
  • --log-format format Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
  • --print-build-logs / -L Print full build logs on standard error.
  • --quiet Decrease the logging verbosity level.
  • --verbose / -v Increase the logging verbosity level.

Miscellaneous global options

  • --help Show usage information.
  • --offline Disable substituters and consider all previously downloaded files up-to-date.
  • --option name value Set the Nix configuration setting name to value (overriding nix.conf).
  • --refresh Consider all previously downloaded files out-of-date.
  • --repair During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
  • --version Show version information.

Options that change the interpretation of installables

  • --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. If file is the character -, then a Nix expression will be read from standard input. Implies --impure. Note See man nix.conf for overriding configuration settings with command line flags.
