Bug ID 652691: Installation fails if only .iso.384.sig (new format signature file) is present

Last Modified: Nov 07, 2022

Affected Product(s):
BIG-IP Install/Upgrade(all modules)

Known Affected Versions:
12.1.0, 12.1.0 HF1, 12.1.0 HF2, 12.1.1, 12.1.1 HF1, 12.1.1 HF2, 12.1.2, 12.1.2 HF1, 12.1.2 HF2, 12.1.3

Fixed In:
13.1.0, 12.1.3.1

Opened: Mar 21, 2017

Severity: 3-Major

Symptoms

Tab completion only will complete the names of ISO images that have an old style signature format ("BIG-IP-version-build.iso.sig"), not the new style ("BIG-IP-version-build.iso.384.sig"). Then, installation will fail even if you type out the full name.

Impact

Tab completion will not show the ISO image, and even if you type out the full name, the installation will fail. An error message will appear in "show sys software status" and /var/log/liveinstall.log .

Conditions

This only happens when signature checking is enabled for ISO images. You can determine this by looking at the value of the DB variable "liveinstall.checksig".

Workaround

Put both types of signature file (.iso.sig and .iso.384.sig) on the device.

Fix Information

Tab completion and installation will now work if the old signature file format (.iso.sig) is missing, and only the new signature format (.iso.384.sig) is present.
