Web UI keeps forcing browser to download the html instead of rendering it in the tab - all browsers

[hazrpg]

• I confirm that this is an issue rather than a question.

Bug report

Ever since the swap to version 2 - I've been unable to access the Web UI. The browser just pops up a download dialog box with the name download as the file (no extension).

When you open up the downloaded file in a text editor you can clearly see it is HTML, and when you open the file in a browser it has the skeleton of the page (firefox) or just the raw html (opera). All chrome-based browsers do the same as opera, tested in Google Chrome, Chromium (open-source), Edge.

The OS I have is up-to-date and it is Ubuntu 22.04.3 - I do have hardware-enablement (hwe) turned on (because I've got an Intel AX210 WiFi card and its only supported on kernel > 5.15).

Steps to reproduce

• Go to any Linux-compatible browser, same experience happens on: google-chrome, microsoft-edge, opera and firefox (as these are the browsers I have installed).
• Go to the address bar and type in http://localhost:8090 and the browser instantly just downloads the page instead of rendering it.

What is expected?

Being able to see the Web UI rendered.

What is actually happening?

The code being downloaded to a file called download.

System

I am unable to access the Web UI so the best I can provide is the version

Stable tried: 2.0.16~jammy
Nightly tried: 2.0.17-beta.1+nightly20240121612d1788857ad2e2e58c27108149f1fb64b9c06f~jammy

I can also provide what hyperiond shows when executed:

I went through the releases on github and it seems that version Hyperion-2.0.15-Linux-x86_64.deb makes the Web UI work. So the issue has started after that version. I can now give my system info below:

Thanks for sharing your finding.
The issue seems not to be related to Hyperion's version, but if the package has been build with Qt5 or Qt6.

I build two packages for Bullseye, one with Qt5 and Qt6 and run them on a standard Pop OS (based on Ubuntu Jammy).
I can reproduce the issue with the Qt6 build while Qt5 works.
Running the Qt6 build on my Ubuntu Jammy development environment, it works.
Seems there is something missing on the basic environment.

We need to further investigate.

Nevertheless, I would recommend that you install packages via our repository and not the pure .deb files.
see https://releases.hyperion-project.org/ for instructions.
Could you install from repo and report, if that works?
That might further indicate what is missing....

[srLinux]

@hazrpg happens to me too, try to install the Hyperion-2.0.16-Linux-amd64.deb from the releases. This is working too, seems to be a different version in the releases then on the apt repositorty. (or Qt5 version on git, Qt6 version on apt, idk)
Unpacking hyperion (2.0.16) over (2.0.16~jammy) ... works for me. And i can confirm this problems starts with the 2.0.16

I noticed, if i stop the process manually and start it via /usr/bin/hyperiond /etc/hyperion/hyperion.config.json as user root webinterface will work too. So i tried to remove the /home/user/.hyperion folder and run it as my default user, does not work.

Unfortunately, I cannot reproduce your error on my fresh installed virtual machine (arm64 instead of amd64). I will try it again natively on an amd64 machine in the next few days. Thanks anyway for the bug report.

@srLinux
May I ask you why you start Hyperion with a json file argument in the terminal?
This behavior has never been supported by Hyperion.ng. You can only overwrite the database directory with the -u or --userdata argument option.

[srLinux]

@Paulchen-Panther this is the default value from the systemd runscript. /etc/systemd/system/hyperion.service
So i think "never been supported" is not right at all!

look here: #476

root@ambilight:~# ls -alt /etc/hyperion/hyperion.config.json
-rw-r--r-- 1 pi pi 17367 Mar 18 2017 /etc/hyperion/hyperion.config.json

It is a path to a file not to a directory. And yes i know to overwrite the database directory, thx anyway :-)
So if it is not supported anymore, the .deb file needs to ask for replace this file. ( /etc/systemd/system/hyperion.service )

And i noticed you just run the install script from the Website (github). But i already mentioned that i installed it via apt install hyperion which not work as expected. I already confirmed that install the .deb manually from the git release like the script do, is working.

Maybe you should try to install and configure a 2.0.15 and overinstall a 2.0.16 to reproduce.

@Paulchen-Panther this is the default value from the systemd runscript. /etc/systemd/system/hyperion.service So i think "never been supported" is not right at all!

Sorry for my mistake. The PR is already 6 years old. So we can no longer talk about default. You can forget that.

root@ambilight:~# ls -alt /etc/hyperion/hyperion.config.json -rw-r--r-- 1 pi pi 17367 Mar 18 2017 /etc/hyperion/hyperion.config.json

Since the Hyperion systemd service has been registered to the current user for a while during installation, the old service is no longer used. Apart from that, the first official deb release came out in 2020. The change in your linked PR was in 2017.

And i noticed you just run the install script from the Website (github). But i already mentioned that i installed it via apt install hyperion which not work as expected. I already confirmed that install the .deb manually from the git release like the script do, is working.

I don't know where you read this, but the easy install script from releases.hyperion-project.org installs the APT releases and not the ones from GitHub.
Have a look at the script:
https://github.com/hyperion-project/hyperion.releases-ci/blob/main/install.sh

Maybe you should try to install and configure a 2.0.15 and overinstall a 2.0.16 to reproduce.

Of course I still do. Many thanks for the tip

[srLinux]

is it
https://releases.hyperion-project.org/
https://apt.hyperion-project.org/
or
https://apt.releases.hyperion-project.org/

this information is not consistent.

i think https://docs.hyperion-project.org/en/user/Installation.html#requirements is outdated. But it was updated a month ago.

[Paulchen-Panther]

https://releases.hyperion-project.org/ is the main page. It contains the installation instructions.
https://apt.hyperion-project.org/ is no longer up to date. A redirect for previous installations has been set up.

https://apt.releases.hyperion-project.org/ is the actual APT server. The installation files for an apt install hyperion come from here.

Yes, the information in the documentation is no longer up to date. I have not yet found the time to change this myself. As this is an open source project, you are welcome to adapt the page and create a PR. Thank you very much
