Error installing: plexmediaserver-ros6-binaries-annapurna_1.4.3.3433-03e4cfa35_armel.deb

I am getting the error, “Cannot install application mediaserver-ros6-binaries-annapurna_1.4.3.3433-03E4cfa35-armel.deb”

when trying to upgrade to plexmediaserver-ros6-binaries-annapurna_1.4.3.3433-03e4cfa35_armel.deb on a ReadyNAS 212.

See attached screen shot.

Thank you,

Same issue with plexmediaserver-ros6-binaries-annapurna_1.5.3.3580-4b377d295_armel.deb .

Any solutions.

I’ve tried rebooting the ReadyNAS.

I’ve tried using both Firefox and Chrome.

I would completely removing the App, but I’m afraid that I may not be able to reinstall and I do not have a copy of my current version.
