[quote=“smit_patil, post:8, topic:13615”]but now i had a new problem,every time when i upgrade my OS the old kernel gets install automatically.I have to remove it again by sudo apt autoremove[/quote]I only just now dropped into this thread, not having read all of it so forgive me if I missed something but how did you install the new kernel?

If you did so manually, you can just remove the meta package for the Linux Ubuntu kernel and it will prevent the update process from installing the old one.

sudo apt-get purge --autoremove linux-generic

However, only do this if you indeed installed 4.10.x manually. We don’t want you ending up without any kernel at all. :wink:
