I found out the reason, which was that my partition table contained "overlapping partitions". However, more information about the error should be displayed, as both fdisk and parted is able to retrieve the information. Any feedback and tips provided to the user during the installation process would be helpful.
I've since repartitioned, and the installer is working well now. ** Changed in: gparted (Ubuntu) Status: New => Invalid ** Changed in: parted (Ubuntu) Sourcepackagename: gparted => parted -- Disk showing up as unpartitioned even though it is not https://bugs.launchpad.net/bugs/215428 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
