[Touch-packages] [Bug 1990624] Re: Removing old kernel-core leaves modules.builtin.alias.bin under /lib/modules

2022-09-23 Thread Nick Rosbrook 
You could try opening a bug for the linux package
(https://launchpad.net/ubuntu/+source/linux), but I'm not sure it is a
bug exactly. Other tools like depmod may add files to
/lib/modules/$version, which causes apt to not remove the
/lib/modules/$version directory so that it does not accidentally delete
data the user did want deleted.

Thanks Nick.

Would you happen to know which component the issue should be assigned
to? (I picked Systemd because of the Red Hat bug).

And I should have provided this in the report. Sorry about that:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

Also, I believe a simple workaround for this is to add a drop-in to
/etc/kernel/install.d that fixes what is missing from
/usr/lib/kernel/install.d/50-depmod.install. See [1] for more details.

Okay, thanks for the additional info. So, you are correct that the red
hat bug does currently apply to 22.04, because we do not have this
upstream commit [1]. However, that bug pertains only to kernel-install,
which is not called in your script. It is also not invoked by apt or the
linux package's maintainer scripts AFAICT.

2022-09-23 Thread Jeffrey Walton 
> Are you invoking kernel-install to remove kernels? Or what action did

Good question, Nick.

I am not using kernel-install. Instead, I use a command like:

   # For the case of 5.15.0-41-generic kernel
   $ sudo apt-get remove --purge '*5.15.0-41*'

In fact, I ran the command manually when I noticed the accumulation of
old kernel parts in /lib/modules. Apt said there was nothing to do.

I knew about the 2016630 bug from Red Hat because I first experienced
the issue on Fedora 35. Now I am seeing it on Ubuntu, too.

Here is the actual script I am running. It looks at the current kernel,
and makes a list of all kernels. It removes the current kernel from the
list of all kernels, and then removes all the old kernels.

# Get a list mostly removed kernels. The kernel and package have been
# removed, but the configuration files and directory remains.
old_kernels=($(dpkg -l | grep linux-image | grep '^rc' | tr -s " " | \
cut -f 2 -d ' ' | sort | uniq))

if [ "${#old_kernels[@]}" -ne 0 ]; then
apt-get remove -y --purge "${old_kernels[@]}" 1>/dev/null
fi

# Get the current kernel
current_kernel=$(uname -r)
version_only=$(get_version ${current_kernel})

echo "Current kernel:"
echo "  ${current_kernel} (${version_only})"

# Get a list of installed kernels. The `grep -v` removes the
# current kernel from the list, which should be the latest kernel.
old_kernels=($(dpkg -l | grep linux-image | grep '^ii' | tr -s " " | \
cut -f 2 -d ' ' | sort -V | uniq | grep -v "${current_kernel}"))

temp_list=()
for k in "${old_kernels[@]}"
do
# Skip the metapackage linux-image-generic
if [[ "${k}" == linux-image-generic* ]]; then
continue
fi
temp_list+=("${k}")
done

# Swap-in the new list
old_kernels=("${temp_list[@]}")

if [ "${#old_kernels[@]}" -eq 0 ]; then
echo "No old kernels found"
exit 0
fi

echo "Old kernels to remove:"
for k in "${old_kernels[@]}"
do
version_only=$(get_version ${k})
echo "  ${k} (${version_only})"
done

for k in "${old_kernels[@]}"
do
version_only=$(get_version ${k})
if ! apt-get remove -y --purge "*${version_only}*"; then
echo "Failed to remove ${k}"
some_error=1
fi

done

apt-get install -y --reinstall linux-image-generic linux-headers-
generic

Fedora is a lot easier to remove old kernels. On Fedora I use:

old_kernels=($(dnf repoquery --installonly --latest-limit=-1 -q))
if [ "${#old_kernels[@]}" -eq 0 ]; then
echo "No old kernels found"
exit 0
fi

if ! dnf -y remove "${old_kernels[@]}"; then
echo "Failed to remove old kernels"
exit 1
fi

Are you invoking kernel-install to remove kernels? Or what action did
you perform exactly? It appears there is a lot more than
modules.builtin.alias.bin leftover in your
/lib/modules/5.15.0-41-generic/.
