The default Ubuntu kernel -generic
package doesn't seem to have symbols in it.
I'm trying to avoid compile a kernel with debug info manually.
Does Ubuntu provide a package with kernel debug symbols?
First create a ddebs.list
using:
echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse" | sudo tee /etc/apt/sources.list.d/ddebs.list
Then add the GPG key for ddebs.ubuntu.com
:
wget -O - http://ddebs.ubuntu.com/dbgsym-release-key.asc | sudo apt-key add -
Then run:
sudo apt-get update
Then install the symbols package using:
sudo apt-get install linux-image-`uname -r`-dbgsym
This is rather huge (>680MB), so prepare for a wait while you download it.
I use the Linux kernel debug symbols for tools like systemtap
on the kernel.
apt-cache search dbgsym
returns pkg-create-dbgsym
only, was it in some other repository?
-dbgsym
packages are in special repositories that you must enable, to install them. This explains how.

apt-get update
results in a warning message: W: GPG error: http://ddebs.ubuntu.com trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY ECDCAD72428D7C01
, that is why I am extending this with a solution for that case.

I tried Colin Ian King's answer and it did not work for me. I found out I must add two extra lines in /etc/apt/sources.list.d/ddebs.list
Edit the file via
sudo nano /etc/apt/sources.list.d/ddebs.list
and add the two lines below
deb http://ddebs.ubuntu.com trusty-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com trusty-proposed main restricted universe multiverse
Replace trusty
with your version that you get when you execute
lsb_release -cs
deb http://ddebs.ubuntu.com focal-updates main restricted universe multiverse
for Ubuntu 20.04.
