Hi Mahmoud,
it seems that some java setup issue is leaking in here.
On Update alternatives (which might be called by some packages postinst) it crashes due to a broken setup.

From your log:
Setting up mysql-common (5.7.20-0ubuntu0.16.04.1) ...
update-alternatives: error: cannot stat file '/usr/lib/jvm/java-8-oracle/bin/javac': Too many levels of symbolic links

Check the path that was mentioned and how the links there are set up (likely a loop).
I couldn't find that path in an official package from Ubuntu.
You most likely need to check from which package/tar/... this file comes to avoid it being recreated that way sooner or later.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
