Questions[mysql](ubuntu)

I have installed MySQL workbench from Snap Store and MySQL server 8.0 using apt. The server is running fine and I can access MySQL shell from terminal. But I am having issues connecting the Workbench to the server. I'm getting

        Cannot Connect to Database Server

Your connection attempt failed for user 'root' to the MySQL server at localhost:3306:

  An AppArmor policy prevents this sender from sending this message to this recipient; type="method_call", sender=":1.125" (uid=1000 pid=7944 comm="/snap/mysql-workbench-community/5/usr/bin/mysql- wo" label="snap.mysql-workbench-community.mysql-workbench- community (enforce)") interface="org.freedesktop.Secret.Service" member="OpenSession” error name="(unset)" requested_reply="0" destination=":1.13" (uid=1000 pid=2044 comm="/usr/bin/gnome- keyring-daemon --daemonize --login" label="unconfined")

Please:

1 Check that MySQL is running on address localhost

2 Check that MySQL is reachable on port 3306 (note: 3306 is the default, but this can be changed)

3 Check the user root has rights to connect to localhost from your address (MySQL rights define what clients can connect to the server and from which machines)

4 Make sure you are both providing a password if needed and using the correct password for localhost connecting from the host address you're connecting from

There no field for entering password. It shows two options store in keychain and clear. On selecting store in keychain it prompts for a password, and I enter the password. But then it shows an error:

Could not store password: An AppArmor policy prevents this sender ...

I'm using Ubuntu desktop 16.04 (upgraded from 15.10).

I had installed phpmyadmin from by apt-get install phpmyadmin. It works if I go to localhost/phpmyadmin but I cannot log into it as root.

I have searched a lot for it. I have found many sources in which they suggest to alter /etc/phpmyadmin/config.inc.php and replace the user and password with 'root' and '' (empty for password). But my config.inc.php is different from theirs. For example in my file, there is no line for user and password and it seems it gets it automatically from another file which is /etc/phpmyadmin/config-db.php. Despite this, I have changed the user and password in that file, but now I get this error:

#1698 - Access denied for user 'root'@'localhost'

What I should do?

Phpmyadmin Version: 4.5.4.1deb2ubuntu1
mysql Ver 14.14 Distrib 5.7.12, for Linux (x86_64) using EditLine wrapper

The answers to related questions forget to:

• remove the MySQL databases
• remove the mysql user
• remove the logs in /var/log

How do I uninstall MySQL completely?

I installed MySQL using sudo apt-get. Now I need to remove it from my system.

How can I do that?

Does anyone have any good ideas as to native MySQL GUI clients for Ubuntu?

So far I've tried MySQL Workbench, which never seemed to work properly, phpMyAdmin which I found a bit slow, and Navicat which is a windows port and runs under wine, but none of these is perfect. In an ideal world, I'm looking for something like a native version of navicat.
