Continuing the discussion from Software Updater vs. Synaptic:
I don’t see much on this so perhaps it’s only a VirtualBox VM issue. The reason it’s related to this topic is the upgraded package involved is found in Synaptic but not Software Updater as I write this.
The package name is fonts-noto-cjk. When upgrading, the terminal output says it’s unpacking the new version over the old version when everything goes nutso. Top shows over a dozen running desktop apps all sucking max CPU and, eventually, the desktop crashes to black. I have 2 16.04 VMs and both behave identically.
Anyone else see this? I might try a live USB boot of 16.04 to see what it does there.
UPDATE: I booted 16.04 live from USB, installed synaptic, ignored dozens of other updates and upgraded JUST this package with no ill affects. So this may very well be a VirtualBox thing. My system is VBox 4.3.38 on UM14.04.
