It doesn't seem like it should be such a pain but it is. I click the button in the update software page and I usually get fails that start out like this:
Downloading http://downloads.lede-project.org/releases/17.01.0/targets/bcm53xx/generic/packages/Packages.gz
*** Failed to download the package list from http://downloads.lede-project.org/releases/17.01.0/targets/bcm53xx/generic/packages/Packages.gz
Takes an awful lot of tries to get my software to Update Lists so I can install Luci-app-sqm at this page:
http://192.168.1.1/cgi-bin/luci/admin/system/packages
I wonder if I am doing something wrong or if there is an easy workaround, like downloading it manually and then loading it some way.
