Unble to install on Azure

[davide445]

Using latest Mattermost 7.4 provided by Bitnami on an Azure VM, I got these errors

• Enabled the Upload in the Config file and using the GUI loading this file I got the message “Unable to find manifest for extracted plugin.” The file was created downloading the official Notes repo, extracting it and coverting with 7-Zip first in tar and next gz.
• Trying to use mmctl give me this error

bitnami@MattermostVM:~/stack/mattermost/plugins$ mmctl plugin add mattermost-plugin-channel-notes-master.tar.gz
Error: cannot read user credentials, maybe you need to use login first: stat /home/bitnami/.config/mmctl/config: no such file or directory
