Roll Back a Broken Linux Mint Update with Timeshift

A broken update leaves your desktop unbootable

You install a routine update on Linux Mint, reboot, and the display manager fails to start. Or a new kernel drops your Wi-Fi connection. You need the system back to how it worked yesterday, but you do not want to reinstall everything or dig through package logs.

The useful takeaway: Linux Mint includes Timeshift, a system snapshot tool that can roll back core operating system files and settings to a previous state. It does not replace a personal file backup, but it is the right tool for undoing system-level changes quickly.

How Timeshift treats your system and your data

Timeshift creates incremental snapshots. On filesystems such as ext4 or XFS it uses rsync to copy only changed system files. On BTRFS it can use native copy-on-write snapshots, which are faster and more space-efficient. Linux Mint installs and configures Timeshift by default on most editions.

By default, Timeshift excludes /home. That means your documents, downloads, and browser profiles are not part of the snapshot and will not be reverted during a restore. This keeps snapshots small, but it also means Timeshift alone is not a disaster-recovery plan for personal data.

A snapshot is not a full disk image. It targets system directories such as /etc, /usr, /var, and bootloader configuration. If you break a configuration file in /etc or install a bad driver package, a restore can bring those files back.

Create a snapshot before risky changes

Open the Timeshift application from the menu. The first time you run it, the wizard asks for a snapshot type. Choose rsync unless your root partition is BTRFS, in which case BTRFS is usually preferable. Select the partition where snapshots will be stored—typically your root partition—and set a schedule, such as daily or weekly, with a snapshot limit like five.

Before a major update or a driver change, create a manual snapshot:

1. Open Timeshift and click Create.
2. Enter a description such as pre-nvidia-driver.
3. Wait for the progress bar to finish. The time depends on how many system files changed since the last snapshot.

You can also create a snapshot from the terminal. Run this command as a user with sudo privileges:

sudo timeshift --create --comments "pre-upgrade $(date +%F)"

Expected result: Timeshift exits without error and the new snapshot appears in the GUI list. Risk: if the snapshot partition is nearly full, creation can fail midway and leave a partial snapshot. Check free space first:

df -h /

A conservative rule of thumb is to keep at least 20–30 GB free on the snapshot partition for a typical desktop installation.

To see existing snapshots and the installed version:

timeshift --list

This command does not require sudo and is safe to run anytime.

Restore after a problem

If the system still boots, open Timeshift, select the snapshot labeled before the problem, and click Restore. Timeshift will ask whether to restore bootloader files and will schedule the restore to run after reboot. It replaces current system files with the snapshot versions and reboots into a recovery environment to complete the operation.

If the system does not boot, you can boot from a Linux Mint live USB, install Timeshift in the live environment, point it at your installed system's root partition, and restore from there.

Remember: restoring reverts system files and installed packages to the snapshot point. It does not restore files in /home because they are excluded by default. If you saved important work to /home after the snapshot, those files remain unchanged, but any system-wide application settings stored outside /home will go back to the snapshot state.

Limitation: snapshots consume space and do not cover everything

Each snapshot uses disk space proportional to the system files that changed since the previous snapshot. Frequent snapshots on a small SSD can fill the drive quickly, which can prevent updates or even booting. Timeshift will delete old snapshots according to the limit you set, but you should still monitor free space.

Timeshift does not back up encrypted LVM volumes without additional setup, and it is not a substitute for backing up personal data. Pair it with Deja Dup, an external rsync script, or another tool that covers /home.

Check that a restore succeeded

After the system reboots from a restore, verify the result:

• Run timeshift --list to confirm the snapshot still exists.
• Check the system logs in /var/log/timeshift/ for errors from the restore operation.
• Test the specific functionality that broke before the restore, such as Wi-Fi or the display driver.

If the problem returns, you may have restored the wrong snapshot or the issue may be in /home or user data, which Timeshift does not manage.

Closing: make snapshots part of your update routine

Timeshift works best when you create a snapshot before you change the system, not after you discover a problem. Enable automatic snapshots, make a manual one before installing proprietary drivers or major PPAs, and keep a separate backup for your personal files. That combination gives you a practical way to recover from bad updates without reinstalling Linux Mint.
