Hello,
I’d like some help, I cannot update my OSMC, everytime I get this error :
“An error occured while installing the following package : (unknown package)”.
So I enabled the debug mode, did the update again, and send the logfile here : https://paste.ubuntu.com/23684487/
But it seems that the logfile only contains informations about the startup…
Thank you for your help 
Malone
We need the output of grab-logs -A please.
As you have been consistently using apt-get upgrade to in an attempt to keep your system upgraded, you’ve likely earned a re-install. We have only ever advised to use apt-get dist-upgrade for command line system maintenance.
Also, are you portforwarding 22 your ssh to the world?

You appear to be getting hammered by bots attempting to access your root account. Exposing SSH on the standard port (22) is literally a worst practice. You will be compromised at some point. If you must expose SSH, at the very least you should be doing so on a non-standard port.
Thank you, I just fixed that SSH problem
