Sysupgrade: Image check failed

On two systems
Netgear R6260 snapshot r20705-1722e23ffc
Netgear WNDR3600 snapshot r20382-34ddd2e545
i can't upgrade with following error message:
root@tritanio:/tmp# sysupgrade firmware.bin
Image check failed.

On both system i can't upgrade via auc or if i use the direct image from

Is there anything currently not working and i have to wait for a new build or was something changed which now prevents on "old" builds to upgrade to newer images?

I assume you running a build generated by asu and installed via auc or luci-app-attendedsysupgrade, right?

Probably the ucert key used for signing the build hasn't been updated and is now expired :frowning:
@aparcar may know more details.

Try uninstalling ucert using opkg remove ucert and retry with auc.

Jep, you are right. After in uninstalled ucert, it was working.
Very strange. Using auc/luci-app_attendedsysupgrade now for a very long time, but this was the first time it failed like that.
