Public bug reported: I am booting an Ubuntu Server 19.10 image (ubuntu-19.10-live-server- ppc64el.iso downloade Jan 18, 2020) on a DVD to install Ubuntu on a RaptorCS Blackbird with an IBM Power9 CPU (ppc64el/ppc64le architecture) with an Samsung 970 EVO Plus M.2 SSD attached via an PCIe v4 adapter card.
The installer does recognize the NVME initially but when the installation finally starts it does no longer recognize the path to the NVMe and says: Error: Could not stat device /dev/disk/by-id/wwn-eui.0025... - No such file or directory ... An error occured handling 'disk-nvme0n1': OSError - [Errno Failed to find device at path: %s] /dev/disk/by-id/wwn-eui.0025... ... Traceback: ... File "/snap/subiquity/1286/lib/python3.6/site-packages/curtin/commands/block_meta.py", line 182, in devsync This possible bug was also reported for Intel architecture: https://egevig.org/linux/installing-ubuntu-server-19-10-on-intel-nuc Current workaround: Follow the installer until you have specified the partitions but do not yet hit Done to apply this workaround: - Press Ctrl+Alt+F2 to enter a console outside of the installation program. - If you are not already in a root shell: Login with the user created earlier in the installation process - Find out your SSD ID /dev/disk/by-id/ - Create a symbolic link to your SSD (try with and without "nvme-" and prefix, eg. "nvme-eui.0025... and "eui.0025...": # If you have more than one NVMe SSD you may have to change device number eg. to <code>/dev/nvme0n2</code> for the second SSD... sudo ln -s /dev/nvme0n1 /dev/disk/by-id/wwn-eui.0025... - Exit the shell by pressing Ctrl+D or typing exit. - Switch back to the installer using Ctrl+Alt+F1. - Now choose "Done" to apply and use the partitions. The installer will continue the installation on this NVME now. ** Affects: debian-installer (Ubuntu) Importance: Undecided Status: New ** Tags: nvme samsung ssd ** Summary changed: - Ubuntu Server installer uses wrong NVMe path for Samsung 970 EVO Plus M.2 SSD (could not stat device - failed to find device at path) + Ubuntu Server 19.10 installer uses wrong NVMe path for Samsung 970 EVO Plus M.2 SSD (could not stat device - failed to find device at path) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866535 Title: Ubuntu Server 19.10 installer uses wrong NVMe path for Samsung 970 EVO Plus M.2 SSD (could not stat device - failed to find device at path) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1866535/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
