      @Rahul,

      The openjdk-8-jdk package already installed on the system, why you want install again? about the error, its clear that you’ve older version of libstdc++-5-dev and system requires libstdc++6 in this case you need to upgrade your system to most recent version, if you want to correct these errors try running the following command:

      $ sudo apt-get -f install

    Hi, How to check the partition where Ubuntu has been installed. When I have Windows-10 as another partition.

    • Ravi Saive says:

      @Rahul,

      In Ubuntu, by default the Windows partition mounted and you can view the partition from the Computer tab on the Desktop or you use following command view the windows mounted partition as shown:

      $ sudo fdisk -l
      

      You will see some-think like:

      /dev/sda5     4892672 1173295103 1168402432 557.1G Microsoft basic data
      
  4. Joginder Singh says:

    In General we are create /boot partition without LVM any Specific reason .

    • Ravi Saive says:

      @Joginder,

      A /boot partition is a partition that includes important files for booting Linux operating system properly,

      When it comes to LVM, the /boot partition must be created separately under normal disk partitioning, because grub boot loaders could not read files from an LVM partition. So, its always better approach to create a separate /boot partition.

      I hope it will clear your confusion…

  5. Rchery says:

    Should also mention that fdisk doesn’t support drives bigger than 2TB, parted/Gparted should be used for larger drives.

  6. David D says:

    Just wanted to note that “format disk” is incorrect as this tool never has formatted a drive/disk. Formatting refers to creating a filesytem and overwriting an old one in some cases. That is more like what mkfs does not what fdisk does. As you have shown, fdisk is a partitioning tool.

  7. Aaron Kili K says:

    Hello
    There is an error in the write up “7. How to Formatting a Partition in Linux”, supposed to be”How to format a partition in Linux”
