@Ryan, Since the installer refuses to install, there are no crash logs that I can provide you with. If you try to install 20.04 onto a disk with the mentioned layout (the "Custom layout" option), you should find that you are unable to choose sda1 and sda3 as destinations for /boot and /. Don't you have a system where you can emulate this (that would be very handy)?
Is the installer log located in the same folder as the crash logs (/run/casper or something like that)? A rant for another time is that the 20.04 installer system has never stored the install and crash logs on installation USB stick. In order to retrieve the logs I've had to use a second USB stick and manually copy files over to it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878890 Title: [Ubuntu Server 20.04 LTS]: Failed Install (subiquity...install_fail/add_info) during partitioning To manage notifications about this bug go to: https://bugs.launchpad.net/subiquity/+bug/1878890/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
