Problems Removing or installing mysql-server on Ubuntu 15.04 "Vivid Vervet"

Question

I had to reinstall my server and was able to grab the /var, /usr, and /etc directory. Once the server was reinstalled, I installed mysql and phpmyadmin. Afterwards, I tried to put my database files back into the new server. All tables came over fine, but when I transferred the user table in the mysql database, I started getting errors, then I couldn't use the "service mysql reload" command because the server didn't recognize any password. So, I decided the remove mysql and reinstall it. Unfortunately I have been having trouble since, dpkg won't configure the package, so I deleted the mysql folder from /var and from /etc... Now dpkg is saying,

root@thegamingcorner:~# apt-get -f install mysql-server-5.6
Reading package lists... Done

Reading state information... Done
mysql-server-5.6 is already the newest version.
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

After this operation, 0 B of additional disk space will be used.

 mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)"
This happens everytime I try to remove, purge, reinstall, or install the package, I looked through some of the similar problems and no answers worked, so far I have tried:
"dpkg --configure -a"
"apt-get install mysql-server --reinstall"
"apt-get remove --purge mysql-server"
"dpkg --purge mysql-server"

I am honestly stuck, and I don't know what to do. Also, if there are logs that were not in the mysql folder, please tell me where to find them so I can post it.

Solution

Alright, I tried something else, What I did was, Copied the backed up /etc/mysql folder from the old verison, renamed my.cnf to mysql.cnf, and ran

    root@thegamingcorner:~# dpkg --configure -a
    Setting up mysql-server-5.6 (5.6.25-0ubuntu0.15.04.1) ...
    update-alternatives: warning: alternative /etc/mysql/my.cnf.fallback (part of link group my.cnf) doesn't exist; removing from list of alternatives

After that, I was able to successfully purge and reinstall mysql.
