Indeed,<br>
you will notice though that any new data which have been produced

</span> I think it's not that easy considering the
associated data. You need to swap them to restart from the
latest version of data from rev 20 to copy to 29.
Explicitely removing that version makes sense in that
context. Have an unrevert command won't convey that
notion.<span class="gmail-m_851519627182071513HOEnZb"><font color="#888888"><br>

</span>You are not doing it wrong :) The
revert command "blacklists" this<br>
particular snap revisions on purpose, so that
you don't reupdate to it.<br>
However, there is a way to get back to it! You
can remove explicitely<br>
that revision (without removing the current
snap). Data associated to<br>
the reverted revision will be cleaned up as
well.<br>
Then, you can refresh.<br>
<br>
In a concrete example with the hello snap:<br>
20 is the revision in the stable channel, 29
corresponds to the revision<br>
in the beta channel.<br>
<br>
# Install and update<br>
$ snap install hello<br>
$ snap list hello<br>
Name Version Rev Developer Notes<br>
hello 2.10 20 canonical -<br>
$ snap refresh hello --beta<br>
$ snap list hello<br>
Name Version Rev Developer Notes<br>
hello 2.10.1 29 canonical -<br>
<br>
# Revert<br>
$ snap revert hello<br>
$ snap list hello<br>
Name Version Rev Developer Notes<br>
hello 2.10 20 canonical -<br>
<br>
# Remove reverted version (and associated
data)<br>
$ snap remove hello --revision=29<br>
hello removed<br>
$ snap list hello<br>
Name Version Rev Developer Notes<br>
hello 2.10 20 canonical -<br>
<br>
# Reupdate<br>
$ snap refresh hello --beta<br>
$ snap list hello<br>
Name Version Rev Developer Notes<br>
hello 2.10.1 29 canonical -<br>
<br>
I hope that answer your questions :)<br>
Cheers,<br>
Didier<br>
