Comment 3 for bug 1582784

Ideally the themes and icons should be found in the .icons or .theme folders at the end of the installation or anyway in a place where a theme chooser like unity-tweak-tool could find them.

As there's currently no post-install step to move the files to the mentioned folders, I think that for the moment the user could enable the theme with a command and set it with another (or using his/her preferred theme chooser).

I created a snap package of an icon theme which uses these concepts:
https://github.com/fcole90/ubuntukylin-icon-theme-snap

It currently works only in devmode.

An additional drawback of the set/enable solution based on copying is that updating the snap package would require to enable the icon/theme again. Probably linking would be a better solution, but symlinking from ~ to files in snap/ results in broken links, maybe due to confinement.
