Android 5 update randomly aborted on my Nexus 4
You could use the Nexus Root Toolkit to sideload the OTA updates.  Links:


Nexus Root Toolkit
Nexus 4 OTA (LRX21T from KTU84P)
Nexus 4 OTA (LRX22C from LRX21T)


Hit Launch in the Advanced Utilities pane, then hit the Sideload Update button, and point to the OTA zip from above.  Follow the instructions.  No typing involved.

I don't know of a single LRX22C from KTU84P OTA.
