Public bug reported: On Ubuntu 18.04, Software Updater informed me that an upgrade to 19.10 was available, so I chose "Upgrade".
The process went reasonably smoothly (except for a "system problem detected" popup at the very beginning, that happens all the time - we are talking "ubuntu" smoothly). In the "Distribution Upgrade" window, the steps "Preparing to Upgrade" and "Setting new software channels" got checked pretty quickly, then "Getting new packages" took several minutes, and then "Installing the upgrades" went on for a few hours, with the progress bar slowly but steadily growing. When the progress bar was almost full, near the end, for some reason it went back to the beginning, while still at the stage "Installing the upgrades". As if the "installing the upgrades" stage had restarted from scratch. That, alone, is a bug. But then, several minutes later, I got distracted, and when I came back, the window was gone. There was absolutely nothing on the screen regarding the upgrade process. Not an error message, not a confirmation message saying the upgrade was complete. I couldn't tell whether it was finished without any confirmation message, or if it had crashed and failed with no error message, or if it was processing something and a new window was going to pop up at any moment, without any "loading" or "wait" indicator. None of the three scenarios is acceptable. I waited a while, also I opened a terminal and had a look at running processes to see if there was something that looked like it could be upgrade-related, and couldn't find any. After several minutes of no apparent activity, I restarted. At first, the system got stuck at a black screen with a blinking cursor (just after selecting Ubuntu from the boot menu). I thought the distributioon upgrade had bricked my computer like almost every time in the past. But fortunately no. I powered it down and restarted again, and it succesfully booted to what it seems to be a fully functional 19.10 (of course, we are talking "ubuntu fully functional"). Pathetic, as usual.
