**What type of hardware are you using** : VPS bought online **What YunoHost version are you running** : 12.1.40.1 **How are you able to access your server** : The webadmin **Are you in a special context or did you perform specific tweaking on your YunoHost instance ?** : No ### Describe your issue Trying to update apps – they deinstall, but don’t reinstall but throw an error: ex. WEKAN. but same for other apps. “Fetch available updates” throws an error (see [2] below) ### Share relevant logs or error messages YunoHost encountered an internal error Really sorry about that. You should look for help on the forum or the chat to fix the situation, or report the bug on the bugtracker. The following information might be useful for the person helping you: Error: “500” Action: “PUT” /yunohost/api/apps/wekan/upgrade Error message: Nothing was restored While processing the action the server said: Collecting files to be backed up for wekan… Declaring files to be backed up… Backing up the MongoDB database… Backup script completed for wekan. (YunoHost will then actually copy those files to the archive). [2] Error: “500” Action: “PUT” /yunohost/api/update/all Error message: Unable to update the cache of APT (Debian’s package manager).
