Collabora Online and phpVirtualBox modules are not listed in software center (neither in Neth-UI nor in Cockpit).
I remember that phpVirtualBox has been removed since 7.6 if i’m not mistaken.
Errr, scratch this, it was WebVirtMgr that was removed in v7.5.
will check it ASAP, thank
Fixed, it will be soon available to the mirrors.
