What now? Well, the issue isn't with OPKG, it's with WGET (see the error at the end of the last couple of lines). Specifically the version of WGET built into BusyBox is the issue. Some mention that it might be a password issue, time issue, being behind a firewall issue, etc. The problem noted here deals with the WGET issue.
The Solution
Download these five items (this article is about the Linksys WRT AC Series of routers, so the proper packages are noted here, if your SoC / CPU architecture is different, download the appropriately compiled packages, start here: https://downloads.openwrt.org/releases/21.02.0/packages/ (21.02.0 is the current version as of the writing of this article)) from here: https://downloads.openwrt.org/releases/21.02.0/packages/arm_cortex-a9_vfpv3-d16/packages/with a web browser or another router with OpenWRT (opkg download WhatEverPackageName)
- wget
- zlib
- librt
- libopenssl
- libpcre
Now the trick is getting them on the router that needs the "fix". Below are some suggestions;
- A USB Flash Drive. This can be an issue if one has a USB Flash Drive already plugged in and using the OpenWRT /overlay functionality. But wait, remember, that eSATA port also facilitates USB 2.0. Both of these solutions requires that the proper drivers be loaded to recognize a USB Flash drive. That's a whole new issue not addressed here.
