|
`nix --repair-path` - re-download path from substituter
|
||
|
|
|
||
|
|
# Synopsis
|
||
|
|
|
||
|
|
`nix-store` `--repair-path` *paths…*
|
||
|
|
|
||
|
|
# Description
|
||
|
|
|
||
|
|
The operation `--repair-path` attempts to “repair” the specified paths
|
||
|
|
by redownloading them using the available 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).
