I just encountered this with version 20.04. I created an ESP partition for 259 MB in the installer, but shows as 247 MB in other partition tools (gparted, fdisk, Windows 10). I didn't notice this until a few days after installing Ubuntu. This is the main problem: it's not clear that it deviates from the most common convention.
I understand cjwatson's point that it's not easy to simply change this. But perhaps it's a much smaller change to notify the user somehow? My recommendation would either be to display a message along the lines of "1 MB shown here is equivalent to 1,000,000 bytes". It can be displayed either at the top of the window, or a separate dialog right before in the installer process. I think this would be very useful. If I saw this message I would have partitioned using gparted instead to get the exact layout that I wanted. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/42065 Title: installer: confusion about partition sizes (1000 vs. 1024 issue) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/partman-base/+bug/42065/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
