I CAN NOT UPDATE

[EmiTT]

I receive the following message:

Could not calculate the upgrade

Problem while updating estimated has occurred.

  That might be caused by:
  * Upgrade to a version of Ubuntu yet published
  * Be running the current version, not yet published, Ubuntu
  * Unofficial software packages not provided by Ubuntu

If none of this applies, report this error using 'ubuntu-bug ubuntu-release-upgrader-core "command in a terminal.

Reviewing the files from your upgrade attempt you seem to have enabled the xorg-edgers-ppa. This will prevent the upgrade as that PPA contains different versions of packages essential to Ubuntu. The page, https://launchpad.net/~xorg-edgers/+archive/ppa, contains details on to how to revert to the official Xorg packages. Thanks.
