Ubuntu-mate 1504 incompatibility with Celeron CPU

[silver.bullet at zoho.com]

The issues unlikely are related to the CPU, since the OP is able to
boot.

The OP still should be able to boot the old kernel, it most likely is
still installed and provided by the GRUB menu or perhaps available in
the cache. However, the kernel unlikely is the issue, there's
moste likely something fishy with the package dependencies.

Perhaps caused by third party repositories, perhaps ...,
perhaps ..., ;).

Hopefully nobody will give advices how to "force fixes" and to install a
replacement for Software Centre. The OP missed to provide information.
It's for sure that the OP's guesses are wrong.

The OP should follow my advices:

>>> ls -l /etc/apt/sources.list.d/

If this shouldn't lead to the culprit, we continue troubleshooting.

For the future the OP should consider to backup the complete install,
before performing an upgrade, so assumed something should went terribly
wrong, the old install could be restored from the backup. But we
shouldn't give hints how to backup at the moment, were to buy and how
to replace the CPU, instead let's start troubleshooting, based on
information provided by command line output and if need be by log
files, but not by information given by fogged crystal balls or by
guesses.
