Public bug reported: This is probably the same as many of the other bug reports already reported on updating from 14.04 or directly installing 16.04, so after reading this bug report, feel free to close it.
I have been using Ubuntu LTS for about 10 years now and never had any serious problems. 16.04 is a total disaster for me. - Starting from a 14.04 desktop system fully patched and doing a dist- upgrade fails leaving many uninstalled packages and package conflicts that I have not been able to fix manually (50-100 packages). I think I know all the tricks for installing almost anything, but no go here. - New Lenovo Yoga 900. Install 14.04 zero problems. Fully update it. dist-upgrade. Same results as above. Note the 14.04 had only Ubuntu packages and was only about a week old before the dist-upgrade. - Retry the dist-upgrade on the above. No go, same problem. - Do a new upgrade from a USB stick of 16.04 on the above system containing 14.04 partially upgraded to 16.04 but not working. It produced a working 16.04, but destroyed my Windows dual boot, and wiped out the Windows recovery partition. This is extremely annoying because I had not made recovery disks. Once I get new install media and re- install Windows 10 (beautiful with a nice touch screen even if it is Windows) I am thinking about sticking to Windows (after 16 years of using Linux on my laptops this is really bad). - Do a fresh install of 16.04 on a tower computer. All goes quite well. However after doing an apt-get upgrade to get fully patched, then part way through loading about 100 packages for a developer's setup, I double click on the Amazon icon, which comes up slowly then totally freezes the system. This is much like the black screen syndrome that Windows used to have -- requires a power off (hold the power button down 10 seconds)! - Reboot after power off in prior case, and things seem to work until I double click on the Amazon button and then close the window. The app crashes with a webapp-container problem. Conclusion: This is not the way to keep happy users. 16.04 is for me unusable. For the first time in a very long time, I am very disappointed. IMO, 16.04 should be considered unstable beta software.
