Troubleshooting and FAQ¶
General¶
Request Entity Too Large¶
This error occurs when your Factory has accumulated too much Target metadata to be signed by TUF. This happens because the targets.json containing all of your Targets that is associated with your Factory grows large over time:
Signing local TUF targets

Solution¶
Pruning (deletion) of Targets is a manual maintenance procedure you must consider when creating Targets over time.
The solution is to prune the Targets that you no longer need using Fioctl. This removes these targets from the targets.json associated with your Factory, allowing the production of new Targets.
Warning
Ensure there are no important devices running on a Target that is about to be
pruned. If you are intending on pruning master, be careful and make sure
you know what you are doing.
You can individually prune/delete targets by their Target number:
fioctl targets prune <target_number>
Or, you can prune by tag, such as devel or experimental:
fioctl targets prune --by-tag <tag>
Aktualizr-Lite Pruning Containers¶
By default, aktualizr-lite will prune Docker containers periodically.
If this behavior is undesirable, it can be worked around by adding
aktualizr-lite-no-prune as a label to Docker containers, or by adding
docker_prune = "0" to the [pacman] section of /var/sota/sota.toml on
a given device.
LABEL aktualizr-lite-no-prune
