I have Ubuntu 14.04 LTS installed on Virtualbox and I wannted to upgrade it to the latest version (16.04 LTS).
I Upgrade it using my software updater, I restart my system. But, after restarting the system I found myself with the same old version (14.04). What's wrong guys?
Any suggestions?
/* Why my question is different to this one.
My question is totally different to the question identified as a possible duplicate. Because I was able to complete the update till the end and the OS asked me to restart the PC to finish the installation.
