During my recent install adventure, I suffered installer crashes at roughly the same point on three attempts. These crashes said they'd start a bug reporter, but did not. They dropped me to the desktop of the live environment, where I attempted to run the installer again, only to get a series of worse errors. My options selected during iinstall on every occasion were as follows: Minimal install, yes to third party drivers, no to census (there's one more option here I can't recall, but that was also checked). Advanced options, no LVM, yes ZFS, yes encryption. No recovery key created. Partitioning was automatic, selecting nvme0n1.
These errors were as follows:
Installer crashed
"We're sorry; the installer crashed. After you close this window, we'll allow you to file a bug report using the integrated bug reporting tool. This will gather information about your system and your installation process. the details will be sent to our bug tracker, and a developer will attend to the problem as soon as possible."
This happened while entering name, username, PC name, etc. As mentioned above, no bug collector, and was dropped to desktop.
Installation failed
"The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again."
Launch installer and repeat. While entering username and the like this time, the error was different:
ERROR!!! [yes, it actually had three exclamation points]
"Error informing the kernel about modifications to partition /dev/nvme0n1p2 -- Device or resource busy. This means Linux won't know aboutany changes you made to /dev/nvme0n1p2 until you reboot -- so you shouldn't mount it or use it in any way before rebooting."
My options were ignore or cancel. I chose cancel.
ERROR!!! [it's a very excitable installer, isn't it?]
"Partitions 2, 3, 4 on /dev/nvme0n1 have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot before making further changes."
I reboot. The next time around, I'm able to install, but there's a VERY significant, easily noticeable hang on the screen for entering username, etc., where it had been failing before. Waiting lets that subside, and afterward, I'm able to complete the install.
I've gone through this several times now, with the same errors. I'm only able to install after getting the fatal errors and rebooting.
The system is
