nix profile upgrade - upgrade packages using their most recent flake
nix profile upgrade [option...] elements...
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
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.
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.
The profile to update.
Common evaluation options:
Pass the value expr as the argument name to Nix functions.
Pass the string string as the argument name to Nix functions.
The Nix store to use for evaluations.
Allow access to mutable paths and repositories.
Add path to the list of locations used to look up
Override the flake registries, redirecting original-ref to resolved-ref.
Common flake-related options:
Commit changes to the flake's lock file.
Use the inputs of the specified flake as registry entries.
Don't allow lookups in the flake registries. This option is deprecated; use
Do not allow any updates to the flake's lock file.
Do not write the flake's newly generated lock file.
Override a specific flake input (e.g.
dwarffs/nixpkgs). This implies
Recreate the flake's lock file from scratch.
Update a specific flake input (ignoring its previous entry in the lock file).
Options that change the interpretation of installables:
Operate on the store derivation rather than its outputs.
Interpret installables as attribute paths relative to the Nix expression expr.
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.
