5.7 Incidents in installation

✅ Installation on RM

✅ Installation on VM

• ☑️ Suggestion 1

• Internal harddisk in order to avoid slow reading/writing access to USB

• ☑️ Suggestion 2
• The iso for the Ubuntu in the VM
• should be inside the downloads folder(internal disk) ⭕️
• never install iso from the external disk ❌
• if you put iso from the USB, it will take a long time

• 😱 Incident: does not install
• If ubuntu does not install
• disable the SVGA
• or disable the 3D

• 😱 Incident:
• everything is installed,
• but the next day, the machine does not boot
• ❓ why does this happen? we gave the required minimum RAM

• 😱 Incident: mouse disappears
• after when everything is installed, mouse disappears
• ❓ why does this happen? not enough graphic power
• 💊 enable 3D acceleration, enable SVGA
• mouse only work when minimum requirements are satisfied
• so before installing, maybe disable 3D acceleration and SVGA

• 💡 Note:
• same .iso can behave differently depending on the host
