It was then that I began to investigate the because of the error and its possible solutions, until I finally discovered that the failure was due to that my username did not belong to the Group “vboxusers“, so I only had to add it to the same.
Ilikuwa kisha kwamba nilianza kuchunguza na kwa sababu ya kosa na ufumbuzi wake, mpaka hatimaye waligundua kwamba kushindwa ni kutokana kwamba username yangu hawakuwa kikundi “vboxusers“, hivyo tu ili kuongeza sawa.
