I am installing CUDA Toolkit on Ubuntu 16.04, in the supported distribution table it's written that the Kernel must be "4.4". When I run:
uname -r
I get "4.10.0-42-generic". I tried to install it but it failed with the following message:
It is likely that 4.10.0-42-generic belongs to a chroot's host
Building initial module for 4.10.0-42-generic
Done.

Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)
So, how can I move back to that version of Kernel?
Note: "I have a specific directory "/boot" for booting files which is 250 MB sized and now it's "%80 full".
E: Sub-process ...line. Can you please edit into your post? Also, are you sure the CUDA Toolkit doesn't work at 4.10? I think the requirement is likely to be minimum requirement, and since your version is newer, it might be fine.sudo apt-get purge linux-image-4.4.0-21-lowlatency?
