Thanks for the logs. There are a few things to fix for curtin and probert;
It appears that your disk has an existing MSDOS MBR on it and 3 partitions, sda1, sda2 and sda5. sda5 is marked as a logical partition, but sda2 was not marked as an extended partition (in which sda5 would be contained). This is a bug between the probe data and curtin converting to a storage config. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861251 Title: 'extended_part_no' referenced before assignment error during install To manage notifications about this bug go to: https://bugs.launchpad.net/curtin/+bug/1861251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
