Opkg update: Signature check failed. Remove wrong Signature file

Installing and Using OpenWrt
1

Hi,
I have a really strange issue after reinstalling a sysupgrade image of OpenWRT on my Fritz!Box 7520 and restoring settings from backup. opkg update fails due to a failed signature check and many popular packages are not available to install, like dnsmasq-full.

Does anyone know how to resolve this?

  • What OpenWrt version did you upgrade from?
  • Did you alter the sysupgrade.conf or the backup file list in LuCI?

Same version, 23.05.5. I wanted to get rid of all the unnecessary packages I installed in the past, which is why I didn't want to simply use the reset functionality. I used Luci to upload and install the sysupgrade image.

No changes of the list in Luci.

cat /etc/sysupgrade.conf 
cat /etc/sysupgrade.conf

You removed a bunch of packages, but kept the config ?

Just repeat the downloads in few hours?

Yes. Is that a problem?

Hah, that solved it. I already tried for quite some time before opening this thread. And now it suddenly works.

Does anyone know why this happened?

Thx everyone for the quick answers!
