Uninstall unremovable QNAP package
In recent QNAP firmware releases, there is a QPKG called “QTS SSL Certificate”, but I don’t want to use that and it just is in the way. But if you look at the context menu, there is no option to remove it.
Change the config
When you really want to remove the application, you have to change a setting in /etc/config/qpkg.conf to be able to remove it. Search for the package name in square brackets like [QcloudSSLCertificate] and change the following line:
Sys_App = 2
to
Sys_App = 1
and save the file. Then you can remove the application from the GUI.
