24 hours ago, Linux kernel 4.4.0-65 appeared as an update on Ubuntu 16.04 update servers. I did not do the update at that time because I was too busy to restart the system because of the update. I attempted to do the update 12 hours ago though and although all other updates appeared and installed properly, the kernel update had vanished.
Kernel 4.4.0-65 update is still nowhere to be found at this time. I have changed update servers just to ensure that this was not a local server issue but the results were the same.
Does anyone know what has happened?
