I am on 2017.04-1, and a security update is available.
When I attempt to install the update in My OSMC, it locates the update. When I agree to exit OSMC to install it, it then spends a very, very long time on that text screen “checking for updates”, which seems unusual. I can see the CPU LED indicating a lot of activity, but I have no idea what it is doing. It’s about 10 minutes or so. Then it says it couldn’t install the package “(unknown package)”.
I wasn’t sure which log would be useful but my apt log is here: https://paste.osmc.tv/deyewetale
I notice that My OSMC says I’m now on 2017.04-2, even though I had that error.
