How to revert to a previous version of a snap package? wekan in this case

The snap packages are awesome for me:

  • Simple.
  • Isolated.
  • So easy installation of complex software, like Wekan.
  • Libraries included.
  • Autoupdates: Install & forget it.

If a future update crashs, it will revert that update even! But this morning Wekan didn't work because of a bug. The update didn't crash because wekan really works, but you can't open a card, then I need to revert it. What could I do?

I confirmed an update in the snap yesterday:

`root@snap:~# changes wekan-ondra
ID Status Spawn Ready Summary
63 Done 2017-03-07T17:38:00Z 2017-03-07T17:38:16Z Refresh snap “wekan-ondra”

root@``` snap:~#``

I tried a fast update, maybe it was reverted in a new update, but not lucky:

root@``` snap:~# snap refresh wekan-ondra snap "wekan-ondra" **has no updates available** root@```` snap`:~#``

Then, I reverted the update and everything was working again:

root@``` snap:~# snap revert wekan-ondra wekan-ondra **reverted to 0.10.1** root@```` snap`:~#``

And the last step, help and report it in Launchpad :)
