I have run into an error while using the updater and I cant see how to resolve. Any help will be appreciated.
Current version is 12.0.3.
Update to Nextcloud 12.0.4 available. (channel: “stable”)
Following file will be downloaded automatically: https://download.nextcloud.com/server/releases/nextcloud-12.0.4.zip
Retry update
Check for expected files The following extra files have been found: crontab
apparently you have an extra file in the root of your nextcloud folder called crontab. You need te (re)move it to an other location before you can update.
You can access the crontab in your system usually with the following command
crontab -e
or for apache user try sudo crontab -u apache -e
or other variation depending on your system OS try sudo crontab -u www.data -e
In your case I would ask the service provider to do it, without root access you will have issues down the road by depending on your service provider. My 2 Cents.
