Updated one of two commonly-used machines and no issue so far.
Also, I took out an old computer the other day that I hadn't touched in I forget how long (a year?). It had Solus on it. Was able to update without issue. I know that's not recommended, but it seemed to work just fine.
Love the OS and am grateful to the Solus team. A Merry Christmas to all! Thank you so much for your continued efforts to offer a computing experience that far surpasses so many other options.
