Collected errors:

• opkg_install_pkg: Checksum or size mismatch for package fping. Either the opkg or the package index are corrupt. Try 'opkg update'.
• opkg_install_cmd: Cannot install package fping.
• opkg_install_pkg: Checksum or size mismatch for package coreutils. Either the opkg or the package index are corrupt. Try 'opkg update'.
• opkg_install_cmd: Cannot install package luci-app-adblock.
  make[2]: *** [Makefile:234: package_install] Error 255
  make[1]: *** [Makefile:171: _call_manifest] Error 2
  make: *** [Makefile:349: manifest] Error 2`

Start by reproducing the 24.10.0-rc5 to 24.10.0 upgrade for profile linksys,ea8300 and inspect the package-install failure reported at Makefile:234, Makefile:171, and Makefile:349. Trace the fping and coreutils checksum or size mismatch; done means the manifest completes without the impossible package-selection error.
