Public bug reported: When using a partitioning option that requires the use of a /boot partition (such as LVM), Ubiquity (in Ubuntu 15.04) creates a rather small /boot partition -- 244MiB in my test:
GPT fdisk (gdisk) version 0.8.10 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Disk /dev/sda: 95509824 sectors, 45.5 GiB Logical sector size: 512 bytes Disk identifier (GUID): 6620D692-A7C3-4054-BD03-C37233564AEA Partition table holds up to 128 entries First usable sector is 34, last usable sector is 95509790 Partitions will be aligned on 2048-sector boundaries Total free space is 3325 sectors (1.6 MiB) Number Start (sector) End (sector) Size Code Name 1 2048 1050623 512.0 MiB EF00 2 1050624 1550335 244.0 MiB 8300 3 1550336 95508479 44.8 GiB 8E00 Although this is adequate for the initial installation, it leaves very little space for expansion. On my test installation, it was 40% full (90MiB used) immediately after installation, with two kernels installed (one of which also had a ".efi.signed" variant installed). The small size of the /boot partition has been causing problems "in the wild," as illustrated by some askubuntu.com questions: http://askubuntu.com/questions/142926/cant-upgrade-due-to-low-disk-space-on-boot http://askubuntu.com/questions/89710/how-do-i-free-up-more-space-in-boot http://askubuntu.com/questions/298487/not-enough-free-disk-space-when-upgrading I recommend increasing the default size of a separate /boot partition to approximately 500MiB; that's normally been adequate for me. Other possible fixes (which I'd implement in addition to a /boot partition size increase, not instead of it) include removing the non- signed kernel when a signed one is installed and automatically removing older kernels when an upgrade is installed. These would require changes to package management rather than Ubiquity, of course. ** Affects: ubiquity (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Log files from system on which auto-created /boot partition is too small." https://bugs.launchpad.net/bugs/1465050/+attachment/4414785/+files/log-files.tgz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1465050 Title: Size of /boot partition is too small To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1465050/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
