[Phone] Building Ubuntu Touch Image for Sony Xperia Z5 Compact

I've been doing some background research into the feasibility of porting Ubuntu Touch to the Sony Xperia Z5 Compact for some time now and am ready to give it a shot. This past week I've been trying to access the git repositories at https://code-review.phablet.ubuntu.com/ using https://wiki.ubuntu.com/Touch/Devices/minato as a guide but have not been able to successfully sync the repositories. I always end up getting some form of the following fetch error:

Fetching projects: 77% (137/177) Fetching project aosp/platform/hardware/qcom/display
fatal: Couldn't find remote ref refs/heads/personal/w-ondra/phablet-xperia_5.1.1_r5
Unexpected end of command stream

error: Exited sync due to fetch errors

Anyone else working on building an Ubuntu Touch image and having issues access this gerrit server? I know that Sony provides all the AOSP binaries for their phones so this should be a completely feasible port.
