Hi everybody,
i updated virtualbox using 'yum update'
but installing the extension pack is not possible:
#######
Das Zusatzpaket /home/user/Virtualbox/6_1_28/Oracle_VM_VirtualBox_Extension_Pack-6.1.28-147628.vbox-extpack konnte nicht installiert werden.
The installer failed with exit code 127: Error creating textual authentication agent: Error opening current controlling terminal for the process (`/dev/tty'): No such device or address.
Fehlercode: NS_ERROR_FAILURE (0x80004005)
Komponente: ExtPackManagerWrap
Interface: IExtPackManager {70401eef-c8e9-466b-9660-45cb3e9979e4}
#######
A authentication window for root password did not appear!
dev/tty is available
Can install the the extension pack via commandline?
This all is on CentOS 7.
Best regards

Re: 6.1.28: cannot install extension pack
OK,
i can't remember changing anything on the centos7 installation.
The last update from 6.1.24 to 6.1.26 were successful.
So i removed virtualbox 6.1.28, install 6.1.26, tried extension pack: failed
It seems that some of the latest Centos7 updates is the reason.
What's necessary for the authentication window?
Requirement for virtualbox ist SDL and QT5
QT5 is not installed, which one must be installed?
Best regards

Yes, see https://www.virtualbox.org/manual/ch08. ... ge-extpackoelk0 wrote:Can install the the extension pack via commandline?
I'm not certain of your other errors, though.
There is generally no need to upgrade Virtualbox to each new version, especially on production hosts that must remain in good condition, until a new feature or security fix is needed.
Also, if you're getting Virtualbox from CentOS's repository, instead of Oracle's, see https://www.virtualbox.org/wiki/Linux_Downloads, then you may be running CentOS's fork of Virtualbox, which we technically don't support. If you want to switch to Oracle's repository, please note that there are prerequisites, see https://www.virtualbox.org/manual/ch02. ... nux-prereq

Re: 6.1.28: cannot install extension pack
On a Linux host, VirtualBox generally uses the QT5 library of the host OS, so whatever QT5 version belongs to your host OS should be the correct one.oelk0 wrote:QT5 is not installed, which one must be installed?
