DB migration to 2.0 doesn't finish

I updated my computers’ Syncthing to 2.0 a few days ago, and although the desktop works fine, my laptop doesn’t seem to finish the DB migration to 2.0 and the web ui doesn’t appear on http://localhost:8384/.

They’re both on Arch and Syncthing 2.0.2, but my laptop is on Ivy Bridge (3rd gen intel). At the time my laptop’s storage was running low (~5GB left) so that could be the issue? My old database (I asssume it’s the one in the index-v0.14.0.db/ directory?) is 583M.

I don’t mind just resetting everything and restarting from scratch, is there a way for me to do that without having to re-pair all my devices?

Anyway thank you all so much for making and maintaining Syncthing, it’s probably one of the most useful programs I have on my computers.

Try 2.0.3 which has a couple of fixes for migration robustness.

It looks completely fixed, thanks!
