Systeminfo:

UCS: 5.0-4 errata798
Installed: fetchmail=6.3.26 mailserver=12.0 ox-connector=2.2.7 oxseforucs=7.10.6-ucs9


Abstract:

Missing configuration "RequiredApps = fetchmail" in ini-file (oxseforucs_*.ini) of App "OX App Suite" since Version 7.10.6-ucs4 leads to App Center _not_ aborting an intended uninstallation of App "Fetchmail" with information about dependency with App "OX App Suite".
Consequently App Center will uninstall package univention-fetchmail (App "Fetchmail") which reverse depends on package univention-ox which reverse depends on package univention-ox-meta-singleserver (App "OX App Suite") effectively uninstalling App "OX App Suite" all well.
Package univention-ox depends on univention-fetchmail since univention-ox_12.0.33, which is from OX App Suite Version 7.10.6-ucs4.


Steps to reproduce:

1. On host with installed App "OX App Suite" (Version 7.10.6-ucs4 or newer) select App "Fetchmail" in App Center for uninstallation.
2. App Center will show summary of package changes happening when removal will be startet:
   "The following software changes on ucs-2201.example.intranet will be applied: 245 packages will be removed"
3. Klick Button "START REMOVAL" and wait until uninstallation in finished.
4. Find in App Center that App "OX App Suite" was removed as well.


Expected behaviour:

1. On host with installed App "OX App Suite" (Version 7.10.6-ucs4 or newer) select App "Fetchmail" in App Center for uninstallation.
2. App Center will abort the intended uninstallation with information about dependency with App "OX App Suite":
   "We cannot continue.
    Fetchmail is required for the following Apps to work.
    * OX App Suite
    Uninstall them first."


Suggested solution:

Add configuration "RequiredApps = fetchmail" to all ini-files (oxseforucs_*.ini) of App "OX App Suite" since Version 7.10.6-ucs4 (oxseforucs_20230201112250.ini and newer).
