Hotpatch upgrades to GitHub Enterprise Server {% ifversion ghes = 3.4 %}3.4.9{% elsif ghes = 3.5 %}3.5.6{% elsif ghes = 3.6 %}3.6.2{% endif %} may fail. Upgrades with the full .pkg are unaffected. If the upgrade fails for your instance, either run the full .pkg upgrade, or work around the issue by performing the following steps.

1. SSH into the affected node.

2. To launch GRUB, run the following command.

   sudo dpkg --configure -a
   

3. In the first GRUB window, you will see a list of devices. Do not modify the selection. Press the Tab key to highlight <Ok>, then press Return/Enter to accept.

4. In the second GRUB window, to continue without installing GRUB, use the arrow keys to highlight <Yes>, then press Return/Enter to accept.

5. After you are returned to the prompt, use ghe-upgrade to start the hotpatch installation again.

If you're unable to upgrade, or if you need further assistance, contact GitHub Support. For more information, see "Creating a support ticket." [Updated: 2022-09-27]
