Fixing Ubuntu Error Deleting Partition: Common Causes

If we run into the “error deleting partition” error message on Ubuntu, it means there’s an issue preventing us from removing a partition from our storage device.

Let’s take a look at some common causes and troubleshooting steps to resolve this problem.

Common Causes

1. We cannot delete a partition that is currently mounted. Any filesystem running on the partition needs to be unmounted before deletion.
2. If the partition contains data being actively used by a program or process, the deletion will fail. This can include swap partitions used by the system.
3. Corrupted data or filesystem errors within the partition can prevent deletion attempts.
4. We might not have the needed privileges to modify partitions on the storage device.
5. In some cases, bugs in the specific disk utility we are using mayy cause unexpected errors during deletion.

Troubleshooting Steps

1. First, open a terminal window and run the `df` command to list all mounted filesystems.

   df
2. Then, identify the partition we want to delete and note the mount point (e.g., `/dev/sdX1`, `/mnt/data`).
3. Next, use the `umount` command with the mount point to unmount the partition:

   sudo umount /mount/point

If the partition is in use by a process, we have to stop the process or force unmount the partition with `umount -l /mount/point`.

Check for Running Processes

We can use tools like `ps aux` or system monitors to identify any processes accessing the partition we want to delete. So, we have to terminate such processes if necessary.

ps aux | grep /mount/point

Verify Permissions

We have to make sure we are running the disk utility with administrative privileges. So, we have to add `sudo` to our command to gain the necessary permissions.

sudo disk-utility-command

Try a Different Disk Utility

If the error persists, we can use a different disk utility like GParted or the command-line tool `fdisk`. These tools might offer additional options or troubleshooting features.

• GParted:

  sudo apt-get install gparted
• fdisk:

  sudo fdisk /dev/sdX
