Hi Pavel!

We're definitely interested in having Secure Boot working as right now
it's one of the major pain point when people try to get started with
Tails on PC.

Our plan is to wait until Debian 10 (Buster) which will likely have
support for Secure Boot.

See https://labs.riseup.net/code/issues/6560#note-9.

I think that tails-dev@??? would be more suited for this
discussion. I'm answering there since you mentioned this Ubuntu
technique that might be relevant to our developers.

Cool, thanks for writing this and letting us know!

I'll let our developers have a look and see if such a technique could be
implemented in Tails before Debian 10 (Buster) scheduled for mid-2019.
