Upgrade 24.10.2 to 24.10.4 fails on Edgerouter X

Installing and Using OpenWrt

The update fails with error about partition table but AFAIK that should have been resolved when I updated to 24.10.2.

What happened when you read the page; including:
" Unfortunately, as of at least sometime around 19.07.2, the OpenWrt build for the factory image fails to produce a valid factory tar file. According to [stman/OpenWRT-19.07.2-factory-tar-file-for-Ubiquiti-EdgeRouter-x](https://github.com/stman/OpenWRT-19.07.2-factory-tar-file-for-Ubiquiti-EdgeRouter-x), the cause is a slightly-too-large kernel image. The stman repo provides a customized build configuration that produces a working factory tar file, and a built images (19.07.2, 21.02, and 22.03) for the ERX. The prebuilt ERX factory image is verified to work with the ERX-SFP and presumably will also work for the EP-R6. For the ERX-SFP (and EP-R6?) when it comes to install the full OpenWrt firmware via sysupgrade, the --force option is required to “switch” back to the right platform."

and other stuff, about upgrading?

I followed all steps including changing partitioning when updating from 23.x to 24.10.2.

I would expect a minor update from 24.10.2 to 24.10.4 to go smoothly compared to the upgrade to 24.10.2.

Did you at some point restore a prior configuration? If so, you also restored the old image version record leading to this situation.

I have 2 copies of the ER-X, so I can failback to a working ER-X in case of failure. It is quite possible this copy was updated to 24.10.2 and had the config of the other 23.x copy restored. That allowed me to put back the working old ER-X when this failed. It has been running without any issue until this upgrade fails.

Any way to update this image version record to 2.0 ?

Can I update the compat_version in /etc/config/system ?

This is it now:

option compat_version '1.1'

Yes, edit that number. Next time say you carried ancient config over unsupported upgrade. That red alert box was there for literate readers, you know.

See this wiki article for more general info.

In this particular case only incompatible change is partitioning. It is safe to edit up the number.

Changed it to 2.0 and owut upgrade went smooth.

Running 24.10.4 now.

Thanks for the speedy support everyone.
