Hello,
for a quite a while I cannot successfully update OSMC. Update fails while updating libasound-2data library. I tried to update it also manually, and below is error returned by apt commands:
http://paste.osmc.io/afadosifub.vhdl
I am not sure how to handle conflict between rbp2-device-osmc package, because as far I know it is an essential package for OSMC 
Full log below:

Thank you very much for any help,
Jakub.
Although your sources.list file no longer shows it, you have previously included a link to the raspberrypi.org repo:

All those packages ending with +rpi1 or +rpi3 have come from the raspberrypi.org repo.
You can try the following:
sudo apt-get update
sudo apt-get install --reinstall libasound2=1.1.3-5
sudo apt-get install --reinstall libasound2-data=1.1.3-5
Hello dillthedog and thank you very much for your reply.
When I try to reinstall those packages, everything runs smoothly until I try to run dist-upgrade again. Running dist-upgrade tries to install again those *-rpi3 packages and it succeeds for libasound2 but fails for libasound2-data. Paste from command line: http://paste.osmc.io/acenosuqov.vhdl
I’m guessing that you didn’t run the apt-get update step.
I guess it’s still in there in the rpi.list file
So as @fzinken spotted, you need to comment out or remove the rpi.list file since it’s causing conflicts.
@dillthedog @fzinken Yes! Removing /etc/apt/sources.list.d/rpi.list worked like a charm 
Thank you both for your help . Problem is now solved .
