I tried installing Sparky years ago and gave up when I knew a lot less about Linux.
Two days ago I decided to try again because I am determined to learn to use Debian Testing as a long-term rolling release. Wow! Fantastic!
The Sparky tools make the OS more manageable. Long term, I am sure issues will arise but with the forum's help and the polished, fine tuning Sparky has developed I am sure there will be no issue too difficult to get a solution for.
Thank again, Sparky devs for helping make Debian a Testing a manageable, "Rolling" os option.
New to linux and testing. I would encourage you to install apt-listbugs. Others might disagree. Possible difficulties in future with Python 3.8 transition and python2-removal. Also apt is going to 2.0 It is not really a 1.x to 2.0 leap; but apt is in charge of upgrades of which there are many in testing.
peace out,
