@Michael Hudson-Doyle, The bug might not appear in your VM.
I think a very very detailed instruction to do what I did is to 1. Work in *buntu 18.04.x LTS which is updated and full-upgraded to be up to date 2. Install mkusb-plug according to comment #14 3. zsync any current Ubuntu desktop Focal daily iso file (Lubuntu and Xubuntu have the smallest iso files). You may want to try with a corresponding Ubuntu 19.10 iso file to see how it should work. 4. I have several brand names and sizes of USB pendrives, but I often use Sandisk Extreme 16 GB. The bug appears with different brand names and sizes, so I think you will get similar results with the USB pendrives that are available. 5. Use mkusb-plug to create a persistent live drive in a USB pendrive. There is a wizard-style user interface, and I think you will use it the right way. Otherwise you can ask. 6. Move the pendrive to another computer and boot it. For me it will boot live-only, but after re-labeling the drive to 'writable' and reboot there will be persistence. The bug appears both in the old style BIOS mode and UEFI mode. As described earlier, this bug appeared some weeks ago. Persistence works with 19.10 and with Focal with casper version 1.438build1 when using the old style label 'casper-rw'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863672 Title: The 'new' persistent live method starting in 19.10 no longer works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1863672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
