Hi, I tried the command for installing 16.04 (I assume that it is only that command you need to run, as Zarosky's guide needs only that command other than the instructions for installing he ubuntu device flashing tool, and when i try it it gets quite far), but when I try it it gets about half way through pushing "ubuntuimages/pool/ubports-ff588f14edd1cd8a7dd7934a8c94537c428a2338b8214dd12bfbffff6a981457.tar.xz" to /cache/recovery/ on the device, and then says it has failed because "no space left on device". What should I do? Is the cache partition on my phone not big enough? It seems to get the ubports recovery menu loaded. I am using a Thea but I don't think this error is anything to do with that? The page for Thea version of postmarketos on their wiki says it is "This device is *literally* motorola-titan but with an 4G/LTE modem (and some under-the-hood regulator changes, but DT manages that), so they use a commonized kernel package." so I assume there is a good chance of your Titan version at least running?
I assume the rootfs file for which the link is dead for vivid version is dead and is not a generic one that I can find somewhere else? So i can't install vivid anymore? Thanks for the port anyway, and for still continuing to work on it!
