error on bin/otrs.Console.pl Admin::Package::UpgradeAll

[steeman]

Hello
when I try to upgrade the packages (needed to upgrade OTRS6) with (bin/otrs.Console.pl Admin::Package::UpgradeAll', I get the folowing error:

Can't perform GET on https://ftp.otrs.org/pub/otrs/misc/pack ... sitory.xml: 500 Can't connect to ftp.otrs.org:443

The strange thing is that I works on my production system, but I want to test some things in a VirtualBox machine (with NAT).
On this testmachine there is no problem to get repository.xml with
wget https://ftp.otrs.org/pub/otrs/misc/pack ... sitory.xml

I also tried to enable
WebUserAgent::DisableSSLVerification but this makes no difference.

Someone has an idea?

PS: now OTRS 6.0.27 and the upgrade to 6.0.29

Linux in VirtualBox is older (Debian . I'll try a more recent version. Maybe is that the reason.

after an upgrade to Debian 10, the problem is solved.
