needed version 5.7 of mysql server for a project. I upgraded from version 5.5 to 5.7 using this tutorial. The upgrade was successful and I am able to use the updated version via command line. However, mysql browsers (mysql-workbench as sqlyog as well as phpmyadmin) stopped working after the upgrade.

Workbench says :

Table 'performance_schema.session_variables' doesn't exist

I can log-in using PHPMyAdmin but unable to select any database. It says

SELECT * FROM data_dictionary.CHARACTER_SETS
MySQL said: Documentation
#1146 - Table 'data_dictionary.CHARACTER_SETS' doesn't exist

During the upgrade the following message appeared.

dpkg: mysql-client-5.5: dependency problems, but removing anyway as you requested:
 mysql-workbench depends on mysql-client; however:
  Package mysql-client is not configured yet.
  Package mysql-client-5.5 which provides mysql-client is to be removed.

which made me think it is because no mysql client is available now. Please advise me how to fix this and get my mysql client up and running.

I am unable to install libmysqlclient, tried reinstalling phpmyadmin with no luck.

I am using Ubuntu 14.04 (32 bits) MySQL version after upgrade :

mysql  Ver 14.14 Distrib 5.7.8-rc, for Linux (i686) using  EditLine wrapper

Thanks
