Affected Product(s):
BIG-IP Install/Upgrade
Known Affected Versions:
12.1.3
Fixed In:
13.1.0, 12.1.3.1
Opened: Mar 21, 2017 Severity: 3-Major
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.
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 .
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".
Put both types of signature file (.iso.sig and .iso.384.sig) on the device.
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.
