I wanted to give LTO compression a try on a snap I maintain, since it showed a huge improvement in loading times. I have the same issue, releasing the snap fails even when using the snapcraft.io builders…
I’m also having this issue. LZO works fine locally but is rejected when trying to upload to the Snap Store. The blog post announcing LZO a few days ago so maybe its not fully live yet?
Hi folks, we are in the process of rolling out automated changes to allow all snaps to use LZO compression, but in the meantime you may find your snaps marked for manual review and someone will be along to allow them through in due time. Thanks for your patience.
The change is committed to the review-tools (thanks @emitorino!) and a request was made to pull this into the store. I suspect that it won’t hit production until next week, but perhaps @roadmr can comment further.
