Hi everyone, I'm using fastboot 1:7.0.0+r33-2 (latest version in repo) on Ubuntu 18.04 and i can't change active slot :
$ fastboot getvar current-slot
current-slot: _b

$ fastboot set_active a
Slot a does not exist. supported slots are:

(just empty lines)

Bootloader is unlocked.

Can anyone confirm that there is a problem with that particular version ? I can't check with the one from SDK Platform Tools at the moment - maybe it's OK with it.
BTW, it is possible to switch slot with locked bootloader ?
