Solved: How to Fix Ubuntu Package Installation Error Due to Read-Only File System

Learn how to troubleshoot and resolve the error that prevents you from installing any packages on Ubuntu 23.10 due to a read-only file system.

Problem

If you are using Ubuntu 23.10 and you encounter an error that prevents you from installing any packages with apt, you might be frustrated and confused. The error message might look something like this:

dpkg: error processing archive /var/cache/apt/archives/linux-headers-6.5.0-10-generic_6.5.0-10.10_amd64.deb (--unpack):
 error creating symbolic link './lib/modules/6.5.0-10-generic/build': Read-only file system

This error indicates that your file system is mounted as read-only, which means you cannot make any changes to it. This can happen due to various reasons, such as disk corruption, hardware failure, power outage, or a bug in the system.

In this article, we will show you how to diagnose and fix this problem, so you can install packages on Ubuntu 23.10 without any issues.

Steps to Fix Ubuntu Package Installation Error Due to Read-Only File System

To fix the error that prevents you from installing any packages on Ubuntu 23.10 due to a read-only file system, you need to follow these steps:

Step 1: Check the File System Status

The first thing you need to do is to check the status of your file system and see if it is indeed mounted as read-only. You can do this by running the following command in a terminal:

mount | grep " / "

This command will show you the mount options for the root partition, which is usually /dev/sda1 or /dev/nvme0n1p1. If you see ro in the output, it means that the file system is read-only. For example:

/dev/sda1 on / type ext4 (ro,relatime,errors=remount-ro)

If you see rw in the output, it means that the file system is read-write. For example:

/dev/sda1 on / type ext4 (rw,relatime,errors=remount-ro)

If your file system is read-only, you need to proceed to the next step. If your file system is read-write, you might have a different problem that is causing the error. You can try to run sudo apt update and sudo apt upgrade again and see if the error persists.

Step 2: Remount the File System as Read-Write

The next thing you need to do is to remount the file system as read-write, so you can make changes to it. You can do this by running the following command in a terminal:

sudo mount -o remount,rw /

This command will remount the root partition with the read-write option. You can verify that the file system is now read-write by running the mount | grep ” / “ command again and checking the output. If you see rw in the output, it means that the file system is read-write. For example:

/dev/sda1 on / type ext4 (rw,relatime,errors=remount-ro)

If you see ro in the output, it means that the file system is still read-only. For example:

/dev/sda1 on / type ext4 (ro,relatime,errors=remount-ro)

If your file system is still read-only, you might have a more serious problem that requires a reboot or a repair. You can try to reboot your system and see if the file system is mounted as read-write after the reboot. If it is not, you can try to run a file system check and repair. If none of these methods work, you might need to backup your data and reinstall Ubuntu 23.10.

If your file system is read-write, you can proceed to the next step.

Step 3: Install the Packages with apt

The final thing you need to do is to install the packages with apt, as you normally would. You can run the following commands in a terminal:

sudo apt update
sudo apt upgrade

These commands will update the package lists and upgrade the installed packages to the latest versions. You should not see any errors related to the read-only file system. If you do, you can try to run sudo dpkg –configure -a and sudo apt-get -f install to fix any broken dependencies or incomplete installations.

Frequently Asked Questions (FAQs)

Question: What is a read-only file system?

Answer: A read-only file system is a file system that does not allow any changes to be made to it. This means that you cannot create, modify, or delete any files or directories on the file system. A read-only file system can be useful for security or performance reasons, but it can also cause problems if you need to install or update any software or settings on the system.

Question: What causes a file system to become read-only?

Answer: A file system can become read-only due to various reasons, such as:

• Disk corruption: If the file system detects any errors or inconsistencies on the disk, it might switch to read-only mode to prevent further damage or data loss.
• Hardware failure: If the disk or the controller that connects the disk to the system fails or malfunctions, the file system might become inaccessible or read-only.
• Power outage: If the system loses power unexpectedly, the file system might not be able to flush the data to the disk properly, resulting in corruption or read-only mode.
• Bug in the system: If the system has a bug or a misconfiguration that affects the file system, it might cause the file system to become read-only.

Question: How can I prevent a file system from becoming read-only?

Answer: You can prevent a file system from becoming read-only by following some best practices, such as:

• Use a reliable and compatible disk and controller for your system.
• Use a UPS or a battery backup to protect your system from power outages or surges.
• Use a journaling file system, such as ext4, that can recover from errors or crashes more easily.
• Run regular file system checks and repairs to fix any errors or inconsistencies on the disk.
• Keep your system updated and patched to avoid any bugs or vulnerabilities that might affect the file system.
