Updater won't check again after cancelling an update

[bitplane]

The updater won't check a second time if you accidentally cancel the update download.

Method:

1. Install 4.0.3 on Raspberry Pi
2. Manually check for updates
3. Select "yes" to update to 4.0.4
4. Cancel because you have an itchy trigger finger
5. Close OpenELEC settings program
6. Open it again, choose manual update

Expected result:

Update process should start again

Actual result:

Update process doesn't start.

thanks for reporting. that's known. unfortunately it wont be fixed for 4.0.x as it is not crash and burn bug and requires non-trivial changes to service.openelec.settings. fix will come in 4.2.x if I am still there to fix it. ping @lfiebach : update_in_progress in resources/lib/modules/system.py better use lockfiles instead of local variable as cancel occurs in oe.py download_file() -> ..
