on a TP-Link TL-WR1043N/ND v2 I've recently upgraded from 18.06.1 to 18.06.2 and I get unsatisfied dependencies while installing luci-app-sqm:
Installing luci-app-sqm (1.2.4-1) to root...
* satisfy_dependencies_for: Cannot satisfy the following dependencies for luci-app-sqm:
* opkg_install_cmd: Cannot install package luci-app-sqm.
Did you upgrade packages?
(if you haven't, don't). I am only checking if this might be the reason for your problem.
I had that package installed before upgrading, but since it disappeared from the menu I think that it got wiped and needs to be installed again.
I didn't installed/upgraded anything else since upgrading to 18.06.2
Maybe I am missing something?
Oh, maybe I need to run
before trying to install any package?
Definitely. Flashing a new image does not retain the user-installed packages.
and then I have updated the wiki page to avoid wasting time again on the next upgrade!
