Certain missing kernel-related metapackages will cause your kernel 
package to be skipped during an update if there is a bump to the ABI 
version of the updated kernel (going from, say, to That's probably the case with the old server, unless you 
pinned that version as Andrew suggested. For the new server, you probably 
have linux-image-generic-lts-utopic installed since you have its kernel 
running on your trusty server. You may want to consider installing linux-
image-generic-lts-vivid soon since utopic will reach EOL this July and 
its kernel package will no longer be updated.
