Fix Roku ‘Not Enough Space’

After using the Roku for a few months, and installing the channels you like, you’ll likely see a “Channel install failed. Could not add channel. There is not enough space to add the selected channel(s).” error message appear. You may also get an error when trying to launch a channel that says “Failed to launch“. The problem usually occurs when a channel that takes a lot of space is loading such as YouTube. This means your Roku has insufficient storage. Unless you somehow free some space, you will not be able to install new channels. Here are some things you can try to help you fix this issue?


Fix 1 – Install Updates

If the Roku has decided to automatically download update files, they could take up space until the update is actually installed. Check under “Settings” > “System” > “System update” to see if you can force the Roku to complete the update.


Fix 2 – Remove Channels

Get rid of channels you rarely use. You can do so by highlighting the channel on the Home screen, then pressing * > “Remove channel“.


Fix 3 – Clear the Cache

This is the fix that usually does the trick! The Roku caches data in memory for quicker access. This data can take up an enormous amount of space after using the device for many hours.

To clear the cache on the Roku, press the following buttons on the remote:

🏠🏠🏠🏠🏠 + ▲ + âĒī¸âĒī¸ + ⏊ī¸âŠī¸

  • Home 5 times
  • Up 1 time
  • Rewind 2 times
  • Fast Forward 2 times

If done correctly, the screen will go black for a few minutes, then your Roku will restart.


Fix 4 – Insert SDCard

If your Roku has a microSD card slot, you can use it to expand the available storage. The Roku Ultra LT is the only current Roku device that supports microSD cards. The older Roku 3 and Roku 4 support one as well.

Once you insert an SD Card into your Roku, the system will automatically use it for installing new channels.


I hope these steps have helped you successfully clear the “Not Enough Space” message on your Roku and you’re back enjoying streaming video.

This post applies to Roku Ultra, Express, Streaming Stick, Streambar, and Roku integrated TCL, Insignia / Toshiba TV models.

  2. The third option worked for me! Thanks for posting this. I couldn’t even install 4 channels without that message appearing.

  3. I added an sdcard to my Ultra and thats worked for me! Still think the apps are taking up too much space… Only have close to 13 installed.

  4. Fix 3 worked like a charm for me. After hitting the button combination the roku cursor went to a blank menu option and froze for a minute and then the tv reset itself and all worked fine. It removed my account sign ins so I had to resign in to all apps but small price to pay to appease two toddlers demanding ‘their shows’. Thanks to whoever posted this originally.
