I have a strange behaviour while upgrading from 24.10.5 to 25.12.0 on my Edgerouter X (ER-X) as already reported in the release thread.
After updating ip6-pd is no longer working but also fw4 is missing from the build. I always do a download first and store the images. While comparing the manifest files for both it is clear, that 25.12.0 is missing fw4. But as the rest looks pretty similar I have no idea why this is happening. I’ll also try local image builder.
Anyway: In case this is an issue with owut/ASU I’m reporting it here and here are the manifest files: https://pastebin.com/pM5RKs90
