see this forum link on how to uninstall :

https://community.tp-link.com/en/business/forum/topic/240904

credits to vlad, for when the link might not work anymore , this is what he did :

remove omada package (it will remove dependencies as well, you may also need to run with --purge option):

dpkg -r omadac   ( I edited this to ad the c )

list the packages (ensure omada package is not there):

dpkg-query -l | less 

install the new package:
dpkg -i omada_v4.2.8_linux_x64.deb

install all dependencies:

sudo apt-get -f install

I did this with 4.3.3, after I made a password cut and paste error (I guess) and was good to go after a reinstall.

I did replace all the "omada" for "omadac"
