Immediately complained... I just tried it again to be sure: mark Qt5-default for installation, window pops up that says such and such packages need to be removed, such and such need to be installed, and asks whether I want to mark the changes. When I hit "mark," the red exclamation mark immediately shows up next to line for Qt5-default, along with all the other icons and colors (red, green, etc.) for all other packages that are affected...

I'll try the command line in some minutes - I decided to try to screenshot the list and use GIMP to cobble it together (it's long)... If I can't get that going within a few minutes, I'll bail and try command line.
OK, commandline easier, here's what it says:
"sudo apt-get install qt5-default
E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 1914 (synaptic)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?"
Oh, wait a second, I think I need to close Synaptic first...
OK, now here's what it says:
"Reading package lists... Done
Building dependency tree
Reading state information... Done
