Update: In my case, the problem is with the partition table on the USB stick.
The USB stick was supplied from the manufacturer with a single FAT32 partition which can be mounted and used just fine by operating systems (Windows, Linux and Solaris). However, it is *not* a complete, contiguously defined partition. By using parted on a booted OS with the USB stick inserted, I blew away the partition and re-created it from scratch to completely fill the device - this worked fine in my case. Then, I re-initialized it with "startup disk creator" and the installation ISO image. This time, the installation procedure did NOT hang at the "starting the partitioner" stage and there were no underlying gparted crashes. I'm not sure why a previous commenter had a problem creating a new partition but it may be worth other folks encountering this problem to try the same. -- gparted crashes at startup - Assertion failed https://bugs.launchpad.net/bugs/558431 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
