3 Ways To Fix “No Space Left on Device” Error In Linux

Last Updated on March 18, 2023 by itsubuntu

Fix “No Space Left on Device” Error In Linux

Are you going through an error like “No Space Left On Device” in Linux and getting frustrated with this then this blog post has a solution for you.

How To Fix “No Space Left on Device” Error In Linux

Make sure that your Linux has enough space in your Linux operating system. There are two Linux commands for getting information about disk space. You can do it with the du and df commands. .

Why Does Linux Show “No Space Left on Device” Despite Of Having Enough Space In Linux?

If you are seeing the “No Space Left on Device” error message despite having sufficient free space on your disk, there must something wrong with your Linux file system.

Fix 2:

Check Inodes On Linux

One of the common issues might be not having enough inodes. In Linux, inodes aren’t unlimited, and running out of inodes before the storage space can give you the “No space left on device” error.

You can easily check the availability of inodes by using the -i flag with the df command.

sudo df -i

This will clearly tell the total number of inodes present in the filesystem, along with the amount currently in use. If there are no free inodes left on your system, this is the source of the “No space left on device” error. Sadly, there is no way to generate or create more inodes. All you can do is delete the unnecessary files to free up inodes.

Fix 2:

Restart Processes Using Deleted Files

The most common reason for seeing this error is a recently deleted file. Even if a file is deleted, the respective process keeps using it, keeping the space reserved even though the file is already deleted. You just need to restart the process to free up the reserved storage.

Run the lsof and grep commands to find the problematic process and restart the affected process with the sudo systemctl restart service_name command or you can just reset them all with the sudo systemctl daemon-reload command.

Fix 3:

Manage Bad Blocks In Linux

Sometimes bad sectors can be the reason for space-related errors. There is no real way to fix this issue, The only thing you can do is mark the bad sectors so that they are no longer used by the file system. You need to configure the file system. Run the following command by booting through a Live CD. This will automatically detect all bad blocks on the drive and mark them as unusable.

sudo fsck -vcck /dev/sda

This replaces the /dev/sda with the path of the drive you want to repair.

Fix TypeCatcher (Google Fonts Installer) does not launch in Ubuntu 22.04

This simple tutorial shows how to fix the launching issue for TypeCatcher in Ubuntu 22.04 or other Linux with Python 3.9 & higher.

TypeCatcher is a simple GTK application to download and install Google webfonts for off-line use. The app is available to install in Ubuntu Software for all current Ubuntu releases. However, it does not launch in Ubuntu since 21.10.

TypeCatcher, download & install Google Fonts

When trying to launch it from command line, it outputs something like this:

Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/typecatcher_lib/”, line 30, in on_activate
self.window = TypeCatcherWindow.TypeCatcherWindow()
File “/usr/lib/python3/dist-packages/typecatcher_lib/”, line 47, in __new__
builder = get_builder(‘TypeCatcherWindow’)
File “/usr/lib/python3/dist-packages/typecatcher_lib/”, line 44, in get_builder
File “/usr/lib/python3/dist-packages/typecatcher_lib/”, line 86, in add_from_file
ele_widgets = tree.getiterator(“object”)
AttributeError: ‘ElementTree’ object has no attribute ‘getiterator’

The issue is because of the removal of getiterator() methods from xml.etree.ElementTree module in Python 3.9, which was deprecated since Python 3.2.

As the announcement indicates, simply use iter() method instead will fix the issue.

Methods getchildren() and getiterator() of classes ElementTree and Element in the ElementTree module have been removed. They were deprecated in Python 3.2. Use iter(x) or list(x) instead of x.getchildren() and x.iter() or list(x.iter()) instead of x.getiterator().

1. First, search for and open a terminal window from either start menu or ‘Activities’ overview depends on your desktop environment.

2. When terminal opens, run command to edit the file that contains the ‘getiterator()’ method (see the first screenshot). In the case, it’s “/usr/lib/python3/dist-packages/typecatcher_lib/”.

sudo gedit /usr/lib/python3/dist-packages/typecatcher_lib/

replace gedit to your favorite text editor, or use nano command line editor that works in most Linux.

3. When files opens, find out and replace tree.getiterator with tree.iter.

For Gedit text editor, just go to menu, click open ‘Find and Replace’ dialog. Finally, insert tree.getiterator as ‘Find’, and ‘tree.iter‘ as ‘Replace with’, then click on ‘Replace All’ button.

For nano text editor, press Alt+R when the file opens in terminal window. Then type tree.getiterator when it indicates ‘Search (to replace)’, hit Enter, and insert tree.iter when prompts ‘Replace with’. Finally, hit Enter and type y. Or, just use arrow keys to find and replace the keyword (there are 2) manually. And, press Ctrl+x, type y, and hit Enter to save changes.

After saving the file, try to launch it either from ‘Activities’ overview or command line, and enjoy!
