Apt upgrade fails (subprocess dpkg-deb --control was killed by signal (Segmentation fault))

Help and Support Raspberry Pi

Hi there,

OSMC used to work well on my raspberry pi2. Then the “sudo apt update && sudo apt upgrade” command couldn’t be finished without errors. So OSMC is still working but I am not able to update the system.

How can I fix this issue so that I am able to update that machine?

I pasted the output of apt upgrade below. You can find all logs here: https://paste.osmc.tv/jicewogave

Thanks for your help!

Dont do “apt upgrade”. (Keeping your OSMC system up to date - General - OSMC)

Updating from the command line

OSMC uses the APT packaging system. As such, OSMC can be fully upgraded via the command line by running the following two commands:

sudo apt-get update
sudo apt-get dist-upgrade
Warning: Avoid running sudo apt-get upgrade as it won’t fully upgrade your system. Be sure to run the above commands instead. Running the former command can break your OSMC installation.

We recommend however that users upgrade via My OSMC. Upgrading via My OSMC will still ensure that all Debian packages are upgraded.

Thanks for your answer. Executing “apt-get update && apt-get dist-upgrade” leads to the same error. Do you have any idea what to do to solve this/ to analyse what is going wrong here?

Thanks in advance.

apt upgrade will cause problems with your system.

If you’ve been regularly running this in the past, you will need to reinstall OSMC.
