#1205 closed System Defect (fixed)

10.0: recent update results in fatal grub error

Reported by: vtm Owned by:
Priority: blocker Milestone:
Component: PC-BSD Updater Version: 10.0-RELEASE
Keywords: grub update boot error Cc: trac-bugs@…


Thinkpad x201 with pcbsd full-disk zfs installation.
While I hadn't used it for a couple of days, I booted the machine the day before yesterday. It installed package updates and then informed about a conversion to a new pbi system.
All appeared to go smoothly until the reboot.
The machine is currently unusable, grub panics into rescue shell telling:

error: symbol 'grub_term_highlight_color' not found.
Entering rescue mode...
grub rescue>

I tried booting from stick in order to edit grubs config, but could't mount the fs.
Googling revealed that Debian folks went through exactly the same calamities a couple of months ago. Hence it appears to be a known bug in grub.
Anyway it keeps me from using pcbsd and accessing my data.
Please advise!

  • Resolution set to fixed
  • Status changed from new to closed

Grab a new PC-BSD pre-release 10.0.3 image off of our website. It just finished uploading so it should show up soon. There is a new tool in the installer that will restamp grub for you which will fix the problem.

Thank you very much for working on this.
Your fix should work well from the current (10.0.3) version onward.

In my case (10.0-RELEASE-P14) it may enable me to manually get it fixed with copying a few required files and some additional tinkering - at least I hope so.
E.g. you rely on being able to call function update_grub_boot. For that under /mnt has first to be updated, etc.

I hope to find more time next weekend, in order to get the issue fixed by myself.
Will update this ticket as soon as I found the time to continue working on it.
Thanks again for your support!

The resolution above does not work.
What works is the procedure listed in bug 1198 (restamping grub).
