Sam,

Sam 写道：

lollypop is missing gsettings-desktop-schemas as dependency, and fails

to start without the package.

Thanks for reporting this, and for trying to fix it. I took a different approach in commit 8ac8b3b3601560c4a455543435276a8cdf61b54e: propagation is, at heart, a kluge, and one that should be avoided whenever possible[0].

I'm closing this bug because it now works for me.

Could you pull, upgrade lollypop, and let me know whether it now works for you?

I couldn't find out how to test the effect

Assuming you already have a Guix git checkout to create the patch, you simply:

 $ guix environment guix
 $ ./configure --localstatedir=/var
 $ make -j `nproc`
 $ ./pre-inst-env guix lollypop

…or something like that :-)

Kind regards,

T G-R
