Public bug reported:

I'm trying to install some ubuntustudio packages (low latency kernel and
settings) on top of Ubuntu 19.04. At a certain point the installer
crashes and reports the following error:

divide by zero
divide by zero
    while executing
"expr 300 + (200 / $nofl * $pct)"
    (procedure "pctunpk" line 2)
    invoked from within
"pctunpk $unpk $getcnt"
    (procedure "install" line 75)
    invoked from within
"install"
    invoked from within
".install invoke"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke]"
    (procedure "tk::ButtonUp" line 22)
    invoked from within
"tk::ButtonUp .install"
    (command bound to event)

I've tried installing the same packages on a Dell XPS 13 and Dell XPS 15
and they both hang at different moments during the installer, but both
whilst trying to unpack packages.
