I had dbeaver-ce_xxx, and I tried both of:

sudo dpkg --purge dbeaver

sudo dpkg --purge dbeaver-ce_xxx

Both got the same result. It was not removed.

However, if (also per Aditya's suggestion) I tried just:

sudo dpkg --purge dbeaver-ce

Then it was removed.

Granted, I had to remove some folders under /usr/share/dbeaver, but that was only because I had put some files there that were not in the original installation.

Just a data point. Maybe it will help with dbeaver-ee.

I had to uninstall it with snap using the following command

snap remove dbeaver-ce

I did it with running command:

sudo dpkg -r dbeaver-ce

Note: I have run this from the same directory where i have run

sudo dpkg -i dbeaver-ce_6.2.3_amd64.deb

You can use below commands

dpkg --purge package_name

--purge will remove all configuration files.

Updated : You can remove the package file in director /var/lib/dpkg/info/ and update source.

rm /var/lib/dpkg/info/[package_name].*
dpkg --configure -a
apt-get update

Then, reinstall your package:

None of these completely worked for me. I needed to delete configuration files (workspaces) that should be removed with an uninstall but are not.

Yes, to remove DBeaver and all associated configuration files:

sudo apt purge dbeaver-ce

OR (I found it no difference in using dpkg):

sudo dpkg --purge dbeaver-ce

THEN

Purges are useless against these files, so you have to remove them yourself.

rm -rf ~/.local/share/DBeaverData

Also note that you'll want to remove any workspace files in your $HOME directory:

rm -rf ~/*workspace6 

DBeaver devel team decided to something awesome and brilliant, which was to store prefs in the ~/.eclipse directory. So you'll need to delete that too.

rm -rf ~/.eclipse
