DaGenix:

I'm seeing the same thing on my Netgear R7800

I just installed via SSH instead of luci web interface using "opkg install luci-app-wireguard", and surprisingly this works well.
So i guess that this is an issue with luci and thus the BUG report should go there. Since everything works when installing from SSH i think this ticket can be closed.

Just for completeness. Here is a screenshot of the error in luci.

jow-:

The bug was within the cgi-io helper which truncated the package lists downloaded by LuCI.

Fixes for master and 21.02 have been merged in openwrt/packages@aff9814 and openwrt/packages@8ca8872 respectively.

Once the package has been rebuilt, you can solve the issue using opkg update; opkg upgrade cgi-io.

The next maintenance release will contain the fixed version of this package.
