Description Felix Botner

see horde app

[horde/mailer/params/port]
Description[de]=SMTP Port
Description[en]=SMTP Port
Type=str
Categories=service-mail

during the app installation, before the actual packages are installed, the appcenter sets horde/mailer/params/port to ''

2016-09-15 10:58:52: set horde/mailer/params/port='' old:

now, the postinst of the horde integration package can't set its default (horde/mailer/params/port?25) and i end up with a broken config.

=> App Center should not set (if not set) or unset (if set) variables which have no value in the App Settings

Fixed in
  univention-appcenter 5.0.22-17.223.201609200055

TextBox widgets (Type=str) with an empty value ('') instead emit None. This should remove the variable. Also fixed a bug in the Advanced attribute of a variable.

OK - variables without default are longer set to an empty string
OK - merged to 4.2-0
OK - YAML
