the right command to start GUI is startx but AFAIK the right command
stated that to see the list of installed bundles an user can execute
'swupd bundle-add --list' or 'ls /usr/share/clear/bundles'.
Unfortunetely the first one list ALL bundles (not the only installed
for install Virtual Box guest addition an user should execute
'install-vbox-lga'. Unfortunately that script requires 'which' that it
doesn't installed so it fails. I installed sysadmin-basic bundle and
now it works.
When do you will provide a public bug tracking system?
