Name

       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).
