gargoyle_1.15.x-x86-64-generic-ext4-combined.img.gz

Luci isn’t even compiled into any of those images, so I don’t know what to tell you.

I downloaded the same file again, burned it to a USB drive again and now gargoyle is up and running.
But unfortunately it still can't install transmission. It gives the following error:
" Dependency libstdcpp6 of transmission-cli cannot be found, try updating your pcket list."

Did you add the appropriate package repository from my site? It is listed below where you downloaded it from

I downloaded the necessary .ipk file and installed it, so I managed to install transmission.
But it is not good that a program is included in the feed, but its dependencies are not...

We don't include or support transmission, so its dependencies are not going to be available unless they are brought in by something else. In the case of libstdcpp, apparently that was not required by anything else.

As it is a kernel dependent package, the vermagic must match. OpenWrt's kernel and Gargoyle's kernel do not match, and they never will. They are incompatible.
You might be able to force install and make it work, but it may also cause issues.

The ultimate solution to this is to compile your own version of Gargoyle and include transmission (and its dependencies).
