its traffic control dependency that i dont know what has happened to it, some routers still have it in their packages but others dont. I am not sure what the reason to this is
There was was major trouble regarding 18.06 download "base" repo where "tc" is located. There are several threads about "base" package repository 403 access...
It should have been now fixed and the repo should again be usable for downloads sine a few minutes ago. Just do "opkg update" and then try reinstalling the package.
Thanks for the reply. Forgive my ignorance, but how do I go about running "okpg update"? Do I run it from somewhere inside the LuCI interface or do I need to SSH into the router? I am fairly new to OpenWRT, but I know some of the basics. Thanks so much!
Many advanced users work with the command line as primary. The equivalent in LuCI is to refresh the list of available software packages on the same page you tried to install it from before and then try installing it again.
Ah I understand. Originally after flash I had the update button and pressed that then tried to install it, but got the error that I posted. Going back to the software page I do not have an update button anymore and trying to install it again I get the same error even after refreshing and logging out and back in. Should I try a reboot and see if the update button shows up again?
I did both. I rebooted and tried a different browser and it looks like that did the trick. I was able to see the Update Lists button, pressed that and search for the luci-app-sqm. Clicked install and voila:
