I don't think this is FDE related, I think this is a transient network thing. This is not a crash we've seen before, but I did see weird subiquity snap build failures this morning that are already resolved without change that look like they are network related.

Please repeat the install on the same setup and see if you get a different result. Thanks!

I made several more attempts, with and without networking and hit what appeared to be the same error condition. However, without FDE it worked (without networking).

We are hitting 60s read timeouts when attempting to perform action=INSTALL step=FINISH for core boot encrypted.

In my case, making the timeout longer allows the step to complete with apparent success, but fails on first boot and recovery key prompts.

Thanks for reporting this. The issue here is that the "seal" operation in snapd can take a very long time. For historic reasons we lock the state during the operation and block other snapd operations (including /v2/changes). This obviously is a bug and we are working on a fix.

Just for the record - there is a draft PR in https://github.com/snapcore/snapd/pull/13171 - the code in there will change after the latest discussions we had and the PR number may actual change (because we may to a prereq PR first with some groundwork) but we are actively working on this.

@Dan if your first boot fails with the long timeout, could you please share your device details and (if possible) the log output of the failed boot?

> log output of the failed boot?

Rather boring, or maybe that is itself a clue:

```
/EndEntire
/EndEntire
<screen clear>
[timestamp] x86/cpu: SGX disabled by BIOS.
Please enter the recovery key for disk /dev/disk/by-partuuid/<uuid>: (press TAB for no echo)
```

> device details

Not sure what would be relevant here. TPM info from dmesg below, tarball of logs attached.
kernel: tpm_tis MSFT0101:00: 2.0 TPM (device-id 0x1A, rev-id 16)
