I update all the time and it’s painless and perfect besides this last one. It’s cinnamon, cinnamon translations, and nemo upgrade. Problem is it downloades them but then I get an error message saying Invalid or Corrupted Package (PGP signature). I tried each update individually and got the same message each time. I also refreshed databases just to be thorough “took a shot” and nothing has worked yet. I believe with all the other complaints today someone might want to check the databases to see if they’ve been screwed with or corrupted and no one has noticed yet. It’s always good to check the file integrity and then logs if something is fishy.
BTW I have tried many many distros and Antergos is the most stable and fastest also.
