Issue | The problem arises if a customer with RSA Authentication Manager 8.2 SP1 applies a recent patch then uninstalls that patch and goes back and installs patch that is older than the recent patch that was previously applied. After installing the older patch the system might not boot. After installing a patch or upgrade which includes a update to the OS kernel, the system may fail to boot properly and report a message on the appliance system console immediately after the boot attempt. such as: Error 15: File not found |
Cause | The issue is that the more recent patches install newer versions of the Linux kernel, which cannot be rolled back. When the Authentication Manager patch is rolled back and then the customer installs an older patch (which may have an earlier version of the kernel), the Linux install tools recognize that the system is already running a newer version of the kernel and so it does not install the older version of the Authentication Manager patch. However, the system bootstrap assumes that it installed the kernel which came with the patch. The bootstrap is looking for the old kernel while the system already has a newer version. |
Resolution | This issue is reported in defect AM-31714. The solution is to manually modify the bootstrap so that it refers to the correct kernel. To complete this task,

Workaround | Using GRUB, change the 18 to a 21 (highlighted in the screen shot in the Issue field) and the appliance will boot. |
