As Sam has said, you have somehow downloaded files from staging. For now we need to focus on the udisks problem. First of all, please run the following to remove previously downloaded files:
cd /var/cache/apt/archives
sudo rm diskmount-osmc_9.99-9_all.deb
sudo rm armv7-udisks-osmc_1.0.5-3_armhf.deb
sudo rm udisks_9.99-9_all.deb
sudo rm udisks-glue_9.99-9_all.deb
sudo rm armv7-udisks-glue-osmc_1.3.5-2_armhf.deb
sudo rm rbp2-device-osmc_1.4.3_armhf.deb
Then run:
sudo apt-get update
sudo apt-get install --reinstall rbp2-device-osmc=1.4.1
sudo apt-get install --reinstall diskmount-osmc=1.4.4
sudo apt-get install --reinstall udisks=1.0.5-1+b1
sudo apt-get install --reinstall udisks-glue=1.3.5-1
sudo apt-get purge armv7-udisks-osmc
sudo apt-get purge armv7-udisks-glue-osmc
I’d be grateful if you would post the full output from the commands. Format it using the </>
“Preformatted text” button.
