nix3-store-repair(1) General Commands Manual nix3-store-repair(1) Warning This program is experimental <../../development/experimental- features.md#xp-feature-nix-command> and its interface is subject to change. Name nix store repair - repair store paths Synopsis nix store repair [option...] installables... Examples • Repair a store path, after determining that it is corrupt: # nix store verify /nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10 path '/nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10' was modified! expected hash 'sha256:1hd5vnh6xjk388gdk841vflicy8qv7qzj2hb7xlyh8lpb43j921l', got 'sha256:1a25lf78x5wi6pfkrxalf0n13kdaca0bqmjqnp7wfjza2qz5ssgl' # nix store repair /nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10 Description This command attempts to "repair" the store paths specified by instal- lables <./nix.md#installables> by redownloading them using the avail- able substituters. If no substitutes are available, then repair is not possible. Warning During repair, there is a very small time window during which the old path (if it exists) is moved out of the way and replaced with the new path. If repair is interrupted in between, then the system may be left in a broken state (e.g., if the path contains a critical system component like the GNU C Library). Options • --stdin <#opt-stdin> Read installables from the standard input. No default installable applied. Common evaluation options • --arg <#opt-arg> name expr Pass the value expr as the argument name to Nix functions. • --arg-from-file <#opt-arg-from-file> name path Pass the contents of file path as the argument name to Nix func- tions. • --arg-from-stdin <#opt-arg-from-stdin> name Pass the contents of stdin as the argument name to Nix functions. • --argstr <#opt-argstr> name string Pass the string string as the argument name to Nix functions. • --debugger <#opt-debugger> Start an interactive environment if evaluation fails. • --eval-store <#opt-eval-store> store-url The URL of the Nix store <../../store/types/index.md#store-url- format> to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them. • --impure <#opt-impure> Allow access to mutable paths and repositories. • --include <#opt-include> / -I path Add path to search path entries used to resolve lookup paths <../../language/constructs/lookup-path.md> This option may be given multiple times. Paths added through -I take precedence over the nix-path configura- tion setting <../../command-ref/conf-file.md#conf-nix-path> and the NIX_PATH environment variable <../../command-ref/env-common.md#env- NIX_PATH>. • --override-flake <#opt-override-flake> original-ref resolved-ref Override the flake registries, redirecting original-ref to resolved- ref. Common flake-related options • --commit-lock-file <#opt-commit-lock-file> Commit changes to the flake's lock file. • --inputs-from <#opt-inputs-from> flake-url Use the inputs of the specified flake as registry entries. • --no-registries <#opt-no-registries> Don't allow lookups in the flake registries. DEPRECATED Use --no-use-registries <../../command-ref/conf-file.md#conf- use-registries> instead. • --no-update-lock-file <#opt-no-update-lock-file> Do not allow any updates to the flake's lock file. • --no-write-lock-file <#opt-no-write-lock-file> Do not write the flake's newly generated lock file. • --output-lock-file <#opt-output-lock-file> flake-lock-path Write the given lock file instead of flake.lock within the top-level flake. • --override-input <#opt-override-input> input-path flake-url Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file. • --recreate-lock-file <#opt-recreate-lock-file> Recreate the flake's lock file from scratch. DEPRECATED Use nix flake update <../../command-ref/new-cli/nix3-flake- update.md> instead. • --reference-lock-file <#opt-reference-lock-file> flake-lock-path Read the given lock file instead of flake.lock within the top-level flake. • --update-input <#opt-update-input> input-path Update a specific flake input (ignoring its previous entry in the lock file). DEPRECATED Use nix flake update <../../command-ref/new-cli/nix3-flake- update.md> instead. Logging-related options • --debug <#opt-debug> Set the logging verbosity level to `debug'. • --log-format <#opt-log-format> format Set the format of log output; one of raw, internal-json, bar or bar- with-logs. • --print-build-logs <#opt-print-build-logs> / -L Print full build logs on standard error. • --quiet <#opt-quiet> Decrease the logging verbosity level. • --verbose <#opt-verbose> / -v Increase the logging verbosity level. Miscellaneous global options • --help <#opt-help> Show usage information. • --offline <#opt-offline> Disable substituters and consider all previously downloaded files up-to-date. • --option <#opt-option> name value Set the Nix configuration setting name to value (overriding nix.conf). • --refresh <#opt-refresh> Consider all previously downloaded files out-of-date. • --repair <#opt-repair> During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths. • --version <#opt-version> Show version information. Options that change the interpretation of installables • --all <#opt-all> Apply the operation to every store path. • --derivation <#opt-derivation> Operate on the store derivation <../../glossary.md#gloss-store- derivation> rather than its outputs. • --expr <#opt-expr> expr Interpret installables <../../command-ref/new- cli/nix.md#installables> as attribute paths relative to the Nix ex- pression expr. • --file <#opt-file> / -f file Interpret installables <../../command-ref/new- cli/nix.md#installables> as attribute paths relative to the Nix ex- pression stored in file. If file is the character -, then a Nix ex- pression is read from standard input. Implies --impure. • --recursive <#opt-recursive> / -r Apply operation to closure of the specified paths. Note See man nix.conf <../../command-ref/conf-file.md#command-line-flags> for overriding configuration settings with command line flags. nix3-store-repair(1)
