Error: divie by zero

[Antonio Roberts]

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.

At no point is the entire distribution to blame. In the future, please report bugs using "ubuntu-bug {packagename}". Based on that alone, this bug is invalid for Ubuntu Studio, but we might have a problem with a particular package.

With that said, I'm marking this bug as incomplete. What method were you using? The tk/tcl references imply you were installing with ubuntustudio-installer, but I cannot be sure.

My apologies for the error.

Yes, I was installing using the Ubuntustudio-installer gui. I've attached a screenshot of the error message and the message log.

On one computer it stalled when installing the lowlatency kernel and on the other it stalled when installing a different package but unfortunately I didn't note down which one.

After about 20 minutes of waiting for the progress bar to complete (it didn't) I restarted my computer and everything appears to be working but I have no way to be sure.

Thank you for that. In that case, please open a terminal and type:

ubuntu-bug ubuntustudio-installer

and report everything that you reported here. This will provide us with additional information, such as some limited information about your system to help us figure out the problem better. Also, attach the screenshot that you just attached.

As I said before, this bug is invalid due to the fact that it's never the distribution itself with the bug, but rather, a component or package thereof.
