Something like this might help:


By specifying all the conflicts in this way, you will force the mesa
packages to be uninstalled. It took us a while to get this right for
Devuan Ascii (Debian Stretch).

I'm not sure how easily you can use this file directly, but just wanted
to quickly indicate we've been through this and (I think) solved this
problem. We could potentially host more of these packages in the Leste
repo (some pvr component), if you'd like.
