apt-get update warning: Ignoring Provides line with DepCompareOp for package…
This had a bounty on it, it was not awarded as there was no good answer… ☹
I tried running apt-get update and got these warnings:
W: Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-max
W: Ignoring Provides line with DepCompareOp for package python-cffi-backend-api-min
W: Ignoring Provides line with DepCompareOp for package python3-cffi-backend-api-max
W: Ignoring Provides line with DepCompareOp for package python3-cffi-backend-api-min
W: You may want to run apt-get update to correct these problems
As instructed, I tried apt-get update again and got the same warnings.
What can I do to fix those?
Full output follows:

I removed all external PPA, yet still get this error: therefore this is not a duplicate of Upgrade from 14.04 to 16.04 successful, but it failed actually?

Solution 1:
This problem happens because your version of apt is "too old" and doesn't support packages that use versioned "Provides:".
You can check your apt version with
apt --version
"versioned provides" were added in apt 1.0.7, but Ubuntu 14.04 ships with apt 1.0.1.
See https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1662227 for more information.
The warning is harmless. If you really want to remove it, you can compile apt from sources to a version that supports versioned provides.
Warning!: Updating apt is potentially dangerous and can break the package manager.
If you choose to do it, follow these steps:
wget http://snapshot.debian.org/archive/debian/20150821T213547Z/pool/main/a/apt/apt_1.0.10.2.tar.xz
tar -xvf apt_1.0.10.2.tar.xz
cd apt-1.0.10.2
./configure
make
Solution 2:
The real solution appears to track down the offending package and ask the PPA maintainer to fix it.
Since the issue happened because of certbot, I opened issue 6063 to tackle this. This comment asked the maintainer of the PPA to fix the problem.
As off Monday 23 October, this has been resolved. Make sure you do
sudo apt-get update
sudo apt-get upgrade
To get the changes.
