Installation Home Assistant OS
1

When I upgraded to 2021.7.4 my terminal characters got scrambled. Is anyone else having this problem?

Here is my system info.

Here is a screenshot of the text.

edit:
I can ssh into the terminal from another computer (ie not lovelace) and the font is fine. I have to reset root’s password to do this. I have tried export TERM=xterm but the command is not accepted.

That is because HaOS is not running an X server since that is not normally needed.

It doesn’t like export.

I am getting closer. If I run lovelace in google chrome the terminal is displayed correctly. If I run it in firefox it has issues.

This only happened on the update to 2021.7.4

Edit. Browser is 90.0.2 64bit running on linux mint

I can’t replicate the problem.

My test server (Home Assistant Supervised on Debian 10) is running 2021.7.4 and the SSH & Web Terminal Add-On 9.0.0. Its web UI correctly renders text (using Firefox 90.0 on Ubuntu 20.04):

EDIT

I don’t have an instance running Home Assistant OS (what you are using) but I would surprised if that difference is responsible for the display issue.

Thank you for investigating.

This is getting a little weirder. If I use the firefox feature setting a web page as a program it displays properly. When inside the browser the characters are truncated. It must be some add-on I am using in the main browser.

I found the problem. Duckduckgo add-on is creating an issue somehow. Thanks @123 for looking at it.

Edit: if you start the duckduckgo add-on after you bring up HA it displays fine.
