How to fix the issue of being unable to create new partition tables during Ubuntu installation?
In Ubuntu, if you are unable to create a new partition table, there could be several reasons and solutions for this issue.
- Device is mounted: Make sure the device to be partitioned is not mounted. You can check if the device is already mounted by running the following command:
sudo df -h
If the device is already mounted, you can use the command “umount” to unmount the device.
sudo umount /dev/sdX
The device path to be uninstalled is /dev/sdX, for example /dev/sda.
- Device is write-protected: Check if the device is set to read-only mode. You can view the device’s read-write properties through the following command.
lsblk -o name,ro /dev/sdX
If the device is set to read-only mode, you can use the chmod command to change the device’s read/write attributes.
sudo chmod +w /dev/sdX
- Equipment damage: If there are hardware issues with the equipment itself, it may prevent the creation of a new partition table. You can try connecting the equipment to another computer to see if you can successfully create a new partition table. If you still can’t create a new partition table on another computer, you may need to replace the equipment.
- Permission issue: Ensure that the current user has enough authorization to create a new partition table. You can try running the partition tool as the root user. Start the partition tool as a root user by using the following command:
sudo parted /dev/sdX
/dev/sdX is the device path to be partitioned.
If the above methods still cannot solve the problem, it is recommended to provide more detailed information for a more accurate diagnosis and solution.
