/home/site/wwwroot/QtBinariesLinux/Syncfusion.WebKitWrapper: Permission denied Azure

Hi,

I have followed all steps in order to get the pdf converter to work with Azure from here: https://www.syncfusion.com/kb/10731/how-to-convert-html-to-pdf-in-azure-app-service-linux-using-net-core

The folder exists on Azure, I have confirmed this. I get the below error when attempting to convert:

{"Success":false,"Code":500,"Message":"/usr/bin/xvfb-run: 184: /usr/bin/xvfb-run: /home/site/wwwroot/QtBinariesLinux/Syncfusion.WebKitWrapper: Permission denied\n"}

I have tried on both B1 and S1 plans. I will however note, when running this command:

apt-get update && apt-get -y install xvfb && apt-get -y install fontconfig && apt-get -y install libssl1.0-dev && apt-get -y install libx11-dev libx11-xcb-dev libxcb-icccm4-dev libxcb-image0-dev libxcb-keysyms1-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-render0-dev libxcb-shm0-dev libxcb-util0-dev libxcb-xfixes0-dev libxcb-xkb-dev libxcb1-dev libxfixes-dev libxrandr-dev libxrender-dev

I do encounter an issue:

E: Package 'libssl1.0-dev' has no installation candidate

Any help will be much appreciated.

To add some further details. I'm using .NET Core 5, WebKitPath

Hi Jonathan, 

 

Thank you for your contacting Syncfusion support.

The libssl1.0-dev package is not supported in docker image with .net 5.0. We can generate the PDF in .net 5.0 using libssl files without installing libssl1.0-dev package. Please refer below steps,  

1. apt-get update
2. apt-get install xvfb
3. Need to add OPENSSL shared objects files in QtBinariesLinux folder. (attached the files in below link)
4. apt-get install libx11-dev libx11-xcb-dev libxcb-icccm4-dev libxcb-image0-dev libxcb-keysyms1-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-render0-dev libxcb-shm0-dev libxcb-util0-dev libxcb-xfixes0-dev libxcb-xkb-dev libxcb1-dev libxfixes-dev libxrandr-dev libxrender-dev

  

UG: https://help.syncfusion.com/file-formats/pdf/convert-html-to-pdf/webkit#troubleshooting 

 

We have attached a required OPENSSL (libssl) shared objects, can you please add these files in the QtBinariesLinux folder. Then try the conversion with .net 5.0 and let us know the result. Please find the libssl files from the below link,   

 

LIBSSL: https://www.syncfusion.com/downloads/support/forum/169182/ze/SSL-110974009 

• Download and extract the file from the above link.
• Copy the libcrypto.so and libssl.so files to QtBinariesLinux folder.
• Then try the conversion and check the resultant PDF document.

Please let us know if you need any further assistance with this.

Thank-you for the prompt reply.

I am however still getting the same error:

{"Success":false,"Code":500,"Message":"/usr/bin/xvfb-run: 184: /usr/bin/xvfb-run: /home/site/wwwroot/QtBinariesLinux/Syncfusion.WebKitWrapper: Permission denied\n"}

UPDATE: ​Wow. After spending all day trying different options it appears I have a solution. When deploying to Azure through Visual Studio 2019 (Publish)  they seem to deploy the web application as a website package and append  WEBSITE_RUN_FROM_PACKAGE to the configuration.

The solution is to upload the files manually. I believe there is no to not deploy as package from VS Studio.

I would strongly recommend updating the documentation alerting users of this as I imagine users are more than likely going to deploy thro
