Mosaico 2.1 has just been released. When I tried to upgrade from Mosaico 2.0 to 2.1 I got several errors as follows:
Unable to remove directory /sites/default/files/civicrm/ext/uk.co.vedaconsulting.mosaico/templates Unable to remove directory /sites/default/files/civicrm/ext/uk.co.vedaconsulting.mosaico Failed to move /tmp/tmp-aBft2l//uk.co.vedaconsulting.mosaico to /sites/default/files/civicrm/ext/uk.co.vedaconsulting.mosaico Error loading module file (/sites/default/files/civicrm/ext/uk.co.vedaconsulting.mosaico/mosaico.php). Please restore the file or disable the module.
Following the upgrade Mosaico then became unusable.
I upgraded Flexmailer at the same time and had no problems. I also checked folder permissions and these looked fine to me. I ran the upgrade process twice and had the same errors both times. has anyone had a similar error?
I thought it might be an error in the extension and posted an issue at Error Upgrading from 2.0 to 2.1, but I guess it could also be my setup, though not sure why it would upgrade Flexmailer without any problems but then have errors upgrading Mosaico.
I am on CiviCRM 5.13.5 with Drupal 7.67
