Bash script to clone active Ubuntu Partition to clone partition

The clone-ubuntu.sh bash script will seamlessly and safely replicate 16.04 LTS into a partition for upgrading to 18.04 LTS:

Confirmation Screen

After selecting a target clone partition it is first verified to be ext4 partition type and is not already mounted. If this test is passed, a confirmation message then appears:

=====================================================================
Mounting clone partition /dev/nvme0n1p8 as /mnt/clone16.04

=====================================================================
PLEASE: Carefully confirm Source (Live) and Target (Clone) partitions

SOURCE (BOOT /):  /dev/nvme0n1p5      TARGET (CLONE):  /dev/nvme0n1p8
ID:               Ubuntu              ID:              Ubuntu
RELEASE:          16.04               RELEASE:         16.04
CODENAME:         xenial              CODENAME:        xenial
DESCRIPTION:      Ubuntu 16.04.3 LTS  DESCRIPTION:     Ubuntu 16.04.3 LTS
 Size  Used Avail Use%                 Size  Used Avail Use%
  44G   17G   26G  40%                  24G   17G  5.8G  74%

NOTE: If you are recloning, new files in clone will be deleted,
      modified files are reset to current source content and,
      files deleted from clone are added back from source.

Type Y (or y) to proceed. Any other key to exit: 

In this example a previous clone has been selected for recloning. The available space on the clone is a mute point because we already know there is enough space available.

If you have multiple Ubuntu installations, please verify you have selected the right partition to clone the currently booted Ubuntu, mounted as / (root), to.

This is your last chance to abort by pressing any key except y or Y.

rsync status display for new clone

When cloning for the first time, rsync will give an update from 0 to 100% of all files created. No files will be deleted or changed as the clone is empty:

clone-ubuntu.sh empty clone.gif

Top ToS ToC Skip

rsync status display when recloning

When rsync reclones it never hits 100% because files that never changed are not copied. There will be delays in the update progress as rsync scans for the next file to be copied and when it deletes new files created in the clone that never existed in the original:

How to upgrade 16.04 LTS clone to Ubuntu 18.04 LTS

This is a “bonus” section that may interest many people.

Reboot your machine. The grub menu will contain a new menu option pointing to the cloned partition. You can also select a specific kernel version from the clone’s Advanced Options menu.

One way to convert the cloned 16.04 LTS to 18.04 LTS is to run:

sudo do-release-upgrade

Note the -d flag was required prior to July 26, 2018 but is no longer necessary.

Read the 18.04 upgrade confirmation carefully.

Before proceeding ensure inactive screen locking is turned off. The upgrade process could crash if your computer goes to the lock screen due to keyboard inactivity.

Summary of 18.04 upgrade process

This section will be machine specific because different apps are installed by different users. Here is a brief summary I made based on notes and memory:

  1. confirmation to proceed: ENTER
  2. packages will be removed: Y
  3. replace longind.conf: Y
  4. Configuration file ‘/etc/sane.d/dll.conf’, default N, take Y
  5. ‘/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf’ Take default N
  6. Configuration file ‘/etc/pulse/default.pa’ default N, take Y
  7. Configuration file ‘/etc/grub.d/30_os-prober’’ default N, take N
  8. Full screen grub menu config appears. Take option: keep the local version currently installed
  9. Configuration file ‘/etc/cron.d/anacron’, default N, take Y to see what
  10. An error message multiple times: /sbin/ldconfig.real: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf.d/x86_64-linux-gnu_EGL.conf: No such file or directory
  11. Non-standard: Configuration file ‘/etc/vnstat.conf’ (display differences 1.13 vs 1.18) take Y
  12. 220 packages are going to be removed. (can take hours) enter Y
  13. To finish the upgrade, a restart is required. Take Y

Note step 10 most people will never see. I have an old nVidia driver installation on my Ubuntu 16.04 I never got around to fully removing. It’s included because you might have similar old packages never fully removed.

Grub changes boot menu to clone under UEFI

Unlike 18.04 upgrades I found the 18.04.1 upgrade changed the Grub UEFI configuration to use the clone’s grub menu instead of the original grub menu as per this answer: Dual boot and the files /boot/grub/grub.cfg – which one is used?

$ sudo cat /boot/efi/EFI/ubuntu/grub.cfg
search.fs_uuid b40b3925-70ef-447f-923e-1b05467c00e7 root 
set prefix=($root)'/boot/grub'
configfile $prefix/grub.cfg

$ sudo grub-install
Installing for x86_64-efi platform.
Installation finished. No error reported.

Running sudo update-grub after booting the original partition isn’t enough to change which grub.cfg is loaded by grub. You need to use sudo grub-install to force grub to use the original partition’s configuration.

Both the original partition and clone partition can use update-grub to maintain their own /boot/grub/grub.cfg file but only one can be used during boot.

Of course if you want grub to use the Clone’s grub menu do not do the above steps on the original’s partition.

Edit history

Edit May 6, 2018 - Information display for an empty clone (target) partition corrected.

Edit August 26, 2018 - Use --inplace option with rsync so large files such as a 2 GB trash file are not duplicated on clone during copy process. This can lead to “out of disk space” error. Comment out /etc/cron.d overrides because users may want to keep or want a different directory altogether. Update instructions to use do-release-upgrade without -d flag because Ubuntu 18.04.1 LTS is now released.
