SPACK v0.17 on RH6

From v0.17, spack does not run on RH6.
The first reason is; python2.7 is needed, and the second; clingo needs to be installed by users, instead of bootstrapping.

I use miniconda for python2.7. Clingo can be installed via miniconda as
$ conda install -c potassco clingo

And also you may want to disable bootstraping as;

% spack bootstrap untrust github-actions

%  spack bootstrap disable

Android 12 on Xiaomi A1

My A1 works on Pixel Experience Android 12. Looks good. Actually, feel better than Poco F3 with MIUI.
