How to manage udisk with the udisk utilities?

  • 772

I'm trying to install the udisks utility. The problem is that it says that I have already the newest version of udisks installed on my computer: 

sudo apt-get install udisks2
Reading package lists... Done
Building dependency tree       
Reading state information... Done
udisks2 is already the newest version (2.1.7-1ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 83 not upgraded.

However, running the following command produces no output which indicates that I don't have it installed:

which udisks2

Running commands like the following one gives me an error:

udisks2 --unmount /dev/sdb
udisks2: command not found
command-line

    To use the udisks2 utility commands, type

    udisksctl

    And you see the options:

    $ udisksctl
Usage:
  udisksctl COMMAND

Commands:
  help            Shows this information
  info            Shows information about an object
  dump            Shows information about all objects
  status          Shows high-level status
  monitor         Monitor changes to objects
  mount           Mount a filesystem
  unmount         Unmount a filesystem
  unlock          Unlock an encrypted device
  lock            Lock an encrypted device
  loop-setup      Set-up a loop device
  loop-delete     Delete a loop device
  power-off       Safely power off a drive
  smart-simulate  Set SMART data for a drive

Use "udisksctl COMMAND --help" to get help on each command.

    Example

    You wanted to unmount a flash drive with udisksctl you will need to get the name of the mounted partition. You can find out with:

    lsblk

    example output:

    NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda            8:0    1 15.2G  0 disk 
└─sda1         8:1    1 15.2G  0 part /media/zanna/4C45-110F

    so I can unmount this device:

    udisksctl unmount -b /dev/sda1

    This is reversible with udisksctl mount -b /dev/sda1

  2. udisks2 is installed in your system.

    There is no command udisks2 that can be run in a terminal.

    So everything looks correct.

    You can use other terminal commands related to udisks like udisksctl.

    See also man udisksd.
