@juliank, the install was done on a nearby test box (near my primary system) simulating a usual install which really will be a MBR/legacy partition table
the GPT was automatically created when I selected new (I'd have chosen MBR if given a choice); the systems where this matters are all MBR and have all four primary partitions already utilized No warning messages were shown I'm sure !. http://iso.qa.ubuntu.com/qatracker/milestones/419/builds/229694/testcases/1302/results is the QA-test report. If a message had shown, I'd likely have realized it was GPT & gone back and created MBR (or pre-prepared as I'd done in most prior QA-test installs in hirsute/this cycle using gparted) as that is my actual intended install case (ie. upgrade an existing/prior Ubuntu install from long ago). The simple 'install' strategy was used ONLY to make it easier to re- produce the problem. Reports made duplicate of this include my actual install boxes with systems I do care about (d755-5, d780 etc). All are multi-boot with all primary partitions already utilized. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1924823 Title: ESP on install medium automatically configured as ESP for install, failing install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1924823/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
