Comment 6 for bug 1883040

syslinux will be wrong package then, sorry.
I don't understand boot process so can't help with cause.

(my focusing on a `calamares` issue on the d755 that didn't have this issue also means I've favored that box in hopes to gain more detail on lubuntu's calamares issue, but do regularly use dc7700 for QA full disk installs)

Will grab *focal* and test that as I'm able (I'm assuming flavor doesn't matter, I had failures with same boxes with lubuntu - http://iso.qa.ubuntu.com/qatracker/milestones/413/builds/214460/testcases/1303/results/ though it wasn't booted on as many http://iso.qa.ubuntu.com/qatracker/milestones/413/builds/214468/testcases/1303/results)
