[SOLVED]Error while updating

I get an update while updating applications

Extracting...
sh: 1: cd: can't cd to /root/post_user_create
Error: Unable to extract installation files

Owncloud keeps on updating every time I run

sudo yunohost app upgrade

owncloud gets updated with successful message every time.

The ending lines after this is

Extracting...
sh: 1: cd: can't cd to /root/post_user_create
Error: Unable to extract installation files

and this goes on in loop.

I am on it. It is related to a bug in the moulinette.

I updated the package moulinette-yunohost in order to avoid this error.

Please tell me if it corrects the issue.

The error is still there.The only thing changed is now there is installation failed message in the end.

+ cd /var/www/owncloud
+ sudo su -c 'php occ app:disable gallery -n -q --no-ansi' owncloud
+ sudo su -c 'php occ upgrade -n -q --no-ansi' owncloud
Error: Installation failed

The loop is still there.

try yunohost app fetchlist and yunohost app upgrade again :wink:

Thank you @kload it gives Success! Upgrade complete message now. :clap:
