How to install kernel header for BBB


I try to install linux kernel header by using:

sudo apt-get install linux-headers-4.19.50-ti-r20

I got errors:

Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package linux-headers-4.19.50-ti-r20
E: Couldn’t find any package by glob ‘linux-headers-4.19.50-ti-r20’
E: Couldn’t find any package by regex ‘linux-headers-4.19.50-ti-r20’

I also downloaded .deb package file, but it was not successfully installed, either.

How to do installation?
Thank you,


@dzhou, maybe run “sudo apt update” first… They are on the apt repository.



Hi Robert,

Thank you for the info.
I tried to find the download site for the above deb files. But no luck. Could you please paste a URL link to these files?

Best Regards,
