Issue in the product installer.


This has been fixed and the fix is available in the latest build of the product. See Installation of the latest update of an Acronis product.

To work around the issue without installing the latest build, there are two possible ways to avoid this issue:

  • Install Acronis Backup & Recovery 10 before installing Hyper-V Linux Integration Services;


  • Rename weak-modules for before the of Acronis Backup & Recovery 10 installation:

    mv /sbin/weak-modules /sbin/weak-modules.saved

  • Install Acronis Backup & Recovery 10;
  • Rename weak-modules back to the original:

    mv /sbin/weak-modules.saved /sbin/weak-modules
