Cannot install any sort of package

[IVCrossway]

Hello, I've been trying to install some packages into OMR (collectd and adblock). I tried to install them via LuCi in the software section, but I always get error 255, no matter which package I choose. Uploading them (downloaded from openwrt website ) gives the same error. I must be doing something wrong. Could you guys help me?

I'll attach the installation logs.
OMR is installed on a Thinkcenter Tiny, x64 CPU and OS.
I didn't touch the opkg configuration, it's the same as the default one.

Found the solution. For some reason even tho I installed the x86_64 version

In /etc/opkg/customfeeds.conf all urls were pointing to the i386_pentium4 version, so obviously they weren't compatible. I changed them to the x86_64 version and now it works just fine.
