Hi team, I’m facing an issue while trying to update the OS on one of my devices. Every time I initiate the update, it gets stuck and eventually shows **“OS update failed”**. I’ve tried restarting the device and reattempting the update, but the problem persists. Other devices are updating fine — it’s just this one that’s causing trouble. Has anyone encountered this before or can suggest steps to troubleshoot and resolve it? Thanks in advance for your support!

Hi @Aditya1 , Can you do me a favour and run `journalctl | grep "VPN connection is"` on the HostOS just to make sure your VPN connection is stable when performing the update? ---

@Aditya1, what device type are you using? Given the TPM errors, I’m guessing `Generic x86_64 (GPT)` with secure boot enabled. True? ---

@rosswesleyporter Yes it is and secure boot enabled ---

> [@Aditya1](#): > > \>\> insufficient space for NV allocation This is the most likely cause. Yes, we’ve encountered this error in the lab and the only solution I could find so far is to clear TPM (tpm2\_clear) and re-flash, which is obviously rather destructive. There may be another solution, we’ll need to check and come back to this here. ---

@ab77 thanks for checking in. Waiting for your response regarding the other solution ---

Hi @Aditya1, A few follow-up questions: - What is the current balenaOS version on the device? - What balenaOS version are you trying to upgrade to? - What hardware (or virtual machine) are you using? - Has the device been provisioned or upgraded an unusual number of times e.g. more than 10? - Are you using the TPM for anything besides secure boot?
