Unable to install mitmproxy.

[soli0002]

I have been attempting to install mitmproxy on my MK7 in almost every way, and coming back to the .ipk file provided here. I get this error while installing:

root@mk7:~# opkg install ./mitmproxy-new_8.1.1-1_mipsel_24kc.ipk 
Unknown package 'mitmproxy-new'.
Collected errors:
 * pkg_hash_check_unresolved: cannot find dependency python3-brotlicffi for mitmproxy-new
 * pkg_hash_check_unresolved: cannot find dependency python3-cssutils for mitmproxy-new
 * pkg_hash_check_unresolved: cannot find dependency python3-urwid for mitmproxy-new
 * pkg_hash_fetch_best_installation_candidate: Packages for mitmproxy-new found, but incompatible with the architectures configured
 * opkg_install_cmd: Cannot install package mitmproxy-new.

Is there a way to work around this? Have I done something wrong?

Thanks for your help
