Partition creation box during installation is too small

[Nairwolf]

From the daily Yakkety Yak image of Xubuntu (20160910), during installation, if I choose the option "something else", I've discovered an editable box too small to display all the content inside.

When you try to "create a partition", for example, the editable box to set the size is too small. If you look my screenshot, you can only see "0108" instead of "500108".

If it doesn't prevent user to set a size, it's a graphical bug annoying... And I don't think this behavior was present before.

This could bug could be related to some graphical theme.

Does this issue appear on hardware or a vm?

[Nairwolf (nairwolf)]

Yes, it was on real hardware.

[Kev Bowring (flocculant)]

Confirmed on hardware to allow for larger partition size.

Checked back on 16.04 as well - ok there.

In order to compare, I've attached a screenshot from 16.04.1

FWIW, in Ubiquity's code you probably have to adjust the width-cars value to accommodate the lengthier strings.

[Simon Steinbeiß (ochosi)]

I have created a patch/merge-request that should restore what we saw in 16.04.

This bug was fixed in the package ubiquity - 16.10.11
