Installing and running mycroft on ubuntu desktop is possible, however limited and without full skills compatibility due to python issues. Specifically relating to different versions of python and urllib, which is a hurdle in getting various skills dependant upon that to work.
All is not lost however due to https://git.covolunablu.org/portaloffreedom/mycroft-core-PKGBUILD which is a effort to resolve such issues. Anyone who can figure out how to apply it and build using it could have a patched mycroft running on a debian/ubuntu desktop.
Having yet to figure it out myself, still remain hopeful of seeing a good native ubuntu package fully patched and with working skills. Mostly the python issues could be potentially handled or resolved by a seperate tool for debian/ubuntu systems to process and correct various projects porting them to work, perhaps part of the autoconf tools or something similar.
In trying to manually install and build mycroft on my desktop the installation will and has become corrupted and even fails to properly work at times, requiring a full wipe and reinstall of it, including the various skills and config folders. Not something simple and easy for everyone, perhaps ubuntu has spoiled many of us in recent years. Feels like this should however have more created for testing and using it on ubuntu systems.
Still when it works and the skills that are compatible so far seem to work well enough, it is a rather impressive project worth further investments, of time, money and such.
