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"
