@Tommy_CZ, Not sure what version number exactly you are looking at.
Usually versions that only have "." in them might be the linux meta
package. The bug was fixed by refreshing the linux-image binary package
but without incrementing the ABI number. That way the linux meta package
will not get updated but the binary should be replaced. As the automatic
update previously stated the binary package would need to be
3.19.0-31.36 (note "-" before the abi number).
