recent update to intel-oneapi-runtime-opencl has broken apt on my linux system

crobar — Fri, 25 Apr 2025 10:04:42 GMT

I recently installed an update for the above package via apt. I get the following error:

Preparing to unpack .../intel-oneapi-runtime-opencl_2025.1.0-973_amd64.deb ...
dpkg: warning: old intel-oneapi-runtime-opencl package pre-removal script subprocess returned error exit status 2
dpkg: trying script from the new package instead ...
dpkg: error processing archive /var/cache/apt/archives/intel-oneapi-runtime-opencl_2025.1.0-973_amd64.deb (--unpack):
new intel-oneapi-runtime-opencl package pre-removal script subprocess returned error exit status 2
openCL has already registered, skipping update-alternatives ...
update-alternatives: warning: forcing reinstallation of alternative /opt/intel/oneapi/redist because link group opencl-intel-runtime is broken
Errors were encountered while processing:
/var/cache/apt/archives/intel-oneapi-runtime-opencl_2025.1.0-973_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

it seem maybe the package fails to unpack

Now apt is broken and I can't update anything n the system.

My system is running Mint Linux 21.1 (which is based on Ubuntu 22.04)

How do I fix this?

The root cause of the problem is the pre-removal script which contains a silly error, and some crazy stuff which I hope is removed in the new version.

I mean this script

/var/lib/dpkg/info/intel-oneapi-runtime-opencl.prerm

the script fails because it sets set -e in the body, but also contains the following function at the top

remove_alternative() { update-alternatives --display "$1" &>/dev/null if [ $? = 0 ]; then update-alternatives --remove "$1" "$2" else echo "Alternative for $1 is not found, skipping ..." fi }

when the following command in this function returns a non-zero exit code the script exits and returns that exit code:

update-alternatives --display "$1" &>/dev/null

Now, as for the crazy stuff, there's also the following snippet:

if [ -e "/etc/OpenCL/vendors" ] ; then rmdir --ignore-fail-on-non-empty "/etc/OpenCL/vendors" 2>/dev/null rmdir --ignore-fail-on-non-empty "/etc/OpenCL" 2>/dev/null if [ -z "$(ls -A /etc)" ] ; then rmdir "/etc" 2>/dev/null fi fi

So there's some possibility this script will decide to just go delete /etc !!!! WTF?

For anyone else struggling with this, replace the script mentioned in the previous post with something like the following and you will be able to fix your installation. I also comment out the dangerous "rmdir /etc" to avoid that possibility.

The immediate problem is solved for me personally, but the general issue should be escalated to the development team for investigation.

consider changing....

to...

if [ -e "/etc/OpenCL/vendors" ] ; then rmdir --ignore-fail-on-non-empty "/etc/OpenCL/vendors" 2>/dev/null rmdir --ignore-fail-on-non-empty "/etc/OpenCL" 2>/dev/null # if [ -z "$(ls -A /etc)" ] ; then # rmdir "/etc" 2>/dev/null # fi fi

just bc some shell's might get cranky

New update has been pushed out, and the issue is still present, and broken my package manager again.
