The OpenALPR open source packages are incompatible with the commercial packages and must be removed.
The OpenALPR open source packages are incompatible with the commercial packages. If you attempt to install the commercial software, you may see an error like the following:
The following packages have unmet dependencies:
Depends libopenalpr2 (= 2.3.0-1build4) but 2.x.x-x is to be installed
You can see if you have open source code by running:
dpkg -l | grep alpr
If the version reports "2.3.x" then it is the open source version.
First you should uninstall any and all OpenALPR open source packages with the following command:
sudo apt-get purge -y openalpr libopenalpr2 libopenalpr-data libopenalpr-dev openalpr-daemon openalpr-utils python-openalpr python3-openalpr
Next you can install the commercial software with:
bash <(curl https://deb.openalpr.com/install)
