Additional information you deem important (e.g. issue happens only occasionally):

This appears to be caused by sonic-net/sonic-utilities#2337. The PR added an implementation for GRUB bootloaders, but not the Aboot bootloader or uboot bootloader (which, I think but am not sure, is used for ARM). Because of this, other images cannot even be installed.

@ycoheNvidia FYI

[saiarcot895]

I see sonic-net/sonic-utilities#2646 will fix this issue.
