Hi,
Installing Click packages from appstore (click scope) in Ubuntu Touch images is unreliable.
I couldn't figure exactly which conditions trigger this, but "pkcon install-local some.click" works, and then installation from the scope works, however if I install straight from the scope it doens't work.
I've straced packagekit doing this and spotted some click traceback being written to a .crash which ends with:
Traceback:

then running dpkg-split:

4520 write(2, "dpkg-split: error: unable to rea"..., 183) = 183
Immediately before, one can see:
4520 geteuid32() = 106
which was set when launching dpkg:
4519 setresgid32(107, 107, 107) = 0
4519 setresuid32(106, 106, 106) = 0
4519 getresuid32([106], [106], [106]) = 0
4519 getresgid32([107], [107], [107]) = 0
Indeed, click install had switched to the clickpkg user:
clickpkg:x:106:107::/nonexistent:/bin/false
So the problem is that .clicks may only be read by phablet user or root, but not by clickpkg.

Hi,
TLDR; download-manager only allows downloads to be readable by phablet (of course root can too), so that clickpkg user can't read them.
