When I’m trying to uninstall phpmyadmin by typing:

sudo apt-get remove phpmyadmin*

I get this:

@rramirezm

Have you tried running without the glob (i.e. using the asterisk)?

sudo apt-get remove phpmyadmin

or simply purging the package:

sudo apt-get purge phpmyadmin

If neither of those work, you may want to run:

sudo apt-get -f install

… and then try running them again. The above will attempt to resolve any dependencies that may otherwise exist.

You can also run:

sudo apt autremove

… to remove the packages listed in the output since they are no longer in use/needed.

If nothing seems to be working, we can remove the dpkg files manually:

rm -r /var/lib/dpkg/info/phpmyadmin.*

… then run:

sudo apt-get clean \
&& sudo apt-get update \
&& sudo apt-get remove phpmyadmin \
&& sudo apt-get purge phpmyadmin

    Hi @jtittle,
    sudo apt-get remove phpmyadmin, sudo apt-get purge phpmyadmin, sudo apt-get -f install returned the same error:

     subprocess installed pre-removal script returned error exit status 2
/var/lib/dpkg/info/phpmyadmin.config: 44: /etc/dbconfig-common/phpmyadmin.conf: Syntax error: "(" unexpected
dpkg: error while cleaning up:
 subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 phpmyadmin
E: Sub-process /usr/bin/dpkg returned an error code (1)

    The final step seemed to work

      Yes, though I would run apt-get update once again to ensure that all packages are synced before running apt-get install.

        Oh no It’s back after running apt-get update and apt-get install phpmyadmin I got this:

          Try running the same again to clean it up:

          sudo rm -r /var/lib/dpkg/info/phpmyadmin.* \
&& sudo apt-get clean \
&& sudo apt-get update \
&& sudo apt-get remove phpmyadmin \
&& sudo apt-get purge phpmyadmin

          Then:

          sudo apt-get update \
sudo apt-get -f install \
sudo apt autoremove

          We can also run:

          dpkg --purge --force-remove-reinstreq phpmyadmin

          That’ll clean up phpMyAdmin as well as any other packages that are no longer in use.

          I spun up a fresh DigitalOcean Droplet to test the phpmyadmin package with an instance of Apache2 and MySQL and the installation went fine, as long as I first installed mysql-server.

          So what I did was run:

          sudo apt-get update \
&& sudo apt-get -y upgrade \
&& sudo apt-get -y install mysql-server

          Then I ran:

          sudo apt-get -y install phpmyadmin

          So the best way to get this straightened out would be to either:

          1). Perform a re-image on the Droplet, if you don’t have an current data on it, or;

          2). Run the following after you’ve ran the above to clean up phpmyadmin:

          sudo apt-get -y purge mysql* apache*

          With them both wiped off the Droplet, install MySQL first and then phpMyAdmin. Previously, the phpMyAdmin package seemed to handle the complete installation just fine, though that doesn’t seem to be the case. I’m not sure if they’ve changed how the package runs or if it’s a fluke, but installing MySQL first and then phpMyAdmin works.

            I’m using Nginx not apache

          • rramirezm February 5, 2017

            I have run:

            sudo rm -r /var/lib/dpkg/info/phpmyadmin.* \

&& sudo apt-get update \
&& sudo apt-get remove phpmyadmin \
&& sudo apt-get purge phpmyadmin

sudo apt-get update \
sudo apt-get -f install \
sudo apt autoremove

dpkg --purge --force-remove-reinstreq phpmyadmin

sudo apt-get -y purge mysql*

            And followed this guide:
            https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-16-04
            To reinstall mysql, and everything looked good. But when I reinstalled phpmyadmin with sudo apt-get -y install phpmyadmin this was the verbose:

            How To Install MySQL on Ubuntu 16.04
            by Hazel Virdó
            MySQL is an open-source database management system, commonly installed as part of the popular LAMP (Linux, Apache, MySQL, PHP/Python/Perl) stack. It uses a relational database and SQL (Structured Query Language) to manage its data. This tutorial will explain how to install MySQL version 5.7 on a Ubuntu 16.04 server. The easy way is `sudo apt-get update && sudo apt-get install mysql-server`.

            Does this means I have to Perform a re-image on the Droplet?

jtittle1 February 5, 2017

@rramirezm

We can run the following command to see if any additional information is provided:

sudo dpkg --configure -a

If that doesn’t produce anything that’s helpful, I would setup a second Droplet for testing.

Once logged in to SSH on the new Droplet, copy and paste the following multi-line command and let it run its course.

sudo apt-get update \
&& sudo apt-get -y upgrade \
&& sudo apt-get -y install build-essential mysql-server

Once the above command has completed and MySQL is installed, please run:

mysql_secure_installation

… and setup your root password (if you didn’t already – not all MySQL packages prompt you to set a root password during setup, so the above command allows you to do that).

Once MySQL is setup, install NGINX. You can do this one of two ways – use the NGINX package that is provided by Ubuntu or add NGINX’s PPA.

I prefer NGINX’s PPA since it’s actually maintained by them, so to install the PPA, we’d run:

sudo add-apt-repository -y ppa:nginx/stable \
&& sudo apt-get update

… and then to install NGINX:

sudo apt-get -y install nginx

At this point we should have MySQL and NGINX installed. We can now install phpMyAdmin by using:

sudo apt-get -y install phpmyadmin

When prompted to choose a web server, don’t choose one (i.e. don’t hit space bar to select a web server – if you do, it’ll install that web server during the process and since you’re using NGINX, we don’t want that). Instead, hit tab and let it run its course. When you hit tab, both of the boxes should be empty, just to confirm.

You’ll then be prompted to setup phpMyAdmin. The first question it’ll ask is:

Configure database for phpmyadmin with dbconfig-common?

Tab over to yes, hit enter – then choose a password and confirm it on the next two prompts. This should complete the setup and phpMyAdmin will be located in:

/usr/share/phpmyadmin

So you then need to setup a server block that will allow you to access it, but since the installation of phpMyAdmin didn’t install PHP-FPM, we should go ahead and install that since NGINX will need it to handle PHP requests:

apt-get -y install php7.0-fpm

From there, if you need help setting up your server blocks, just let me know. The above, however, should help to get you running up to the server block portion.

After running sudo dpkg --configure -a it prompted:

Setting up phpmyadmin (4:4.5.4.1-2ubuntu2) …

It looks like I’ll have to deploy another droplet

So whenever anyone wants to remove phpmyadmin and apache just first of all stop all running services using below commands…
stop apache2

sudo systemctl stop apache2.service

prevent apache2 to start at boot

sudo systemctl disable apache2.service
