@lakotaubp got it

I was in devel branch and the current version is 721, I wanted to switch to edge branch, then the updater found a update, but the new version is 710…?? What? That’s downgrade?
I’m not dare to install it, and I’m also not really sure whether edge branch is in development
My device is redmi 4x santoni

@mrlee Well I saw it when Ubports was pushing files to /cache, but /cache space is smaller than these .xz files, so it won't continue. sorry I'm just a chinese, my english isn't very well

@moem As you can see... santoni is Redmi 4X

My problem is worse, I even couldn't install because /cache part space is small
Oh right, my device is also Redmi 4X
