Opkg is an epic imbecile among package managers. I think it's complaining because the package file you're installing has a different MD5 hash than the one in the repos (no kidding?). I don't think there's a force override for this, you just have to install it manually.<br>
<br>Run:<br>ar x file.ipk<br>and then you need to extract data.tar.gz to /<br><br>The downside to this is that opkg has no idea that you installed it, and therefore can't update it or remove it.<br>
