So any guidance out there for getting wkhtmltopdf to work? I am using the 64 bit ubuntu trusty binary
              
Hi guidingstarcc,
I poked around a bit and I can confirm that the following code works with our experimental docker consoles, but not with the standard console (let us know if you want us to switch that on for you- also note that we don't have docker for webapps or scheduled tasks yet):
wget https://bitbucket.org/wkhtmltopdf/wkhtmltopdf/downloads/wkhtmltox-0.13.0-alpha-7b36694_linux-trusty-amd64.deb
dpkg-deb -x wkhtmltox-0.13.0-alpha-7b36694_linux-trusty-amd64.deb wkhtml-install
xvfb-run --auto-servernum ./wkhtml-install/usr/local/bin/wkhtmltopdf http://google.com google.pdf
and then navigating via the files tab to download and open google.pdf
I also saw the same errors as you with Qt and xkbcommon when doing the conversion.
              
Hi conrad,
thanks for the assistance!
I need this for use with django-wkhtmltopdf. It runs wkhtmltopdf in a subprocess; I am guessing  that is a child of the web application shell/console/runtime, so docker is not available.
Can you confirm? Whats the timeframe on getting docker consoles running for webapps/scheduled tasks?
              
Hi, i'm trying to generate a pdf with wkhtmltopdf and it returns a Permission Error [Errno 13] when I try this :  pdfkit.from_string(html, file, css = css_path,configuration = config, options = options)
Any help ?
              
I should correct what I was saying above; pdfkit uses the WebKit rendering engine and QT; in theory that could work using a virtual frame buffer (eg. a fake display that doesn't actually show anywhere, but does exist in memory).  But right now WebKit doesn't work on PythonAnywhere due to the way our virtualization system works.
              
I want to install wkhtmltopdf to my server as well.
How to get access to new virtualization system.
Plus, let me know if it's going to harm my current or stop my site which is running since few years.
              
I've switched on the new virtualization system for your account -- any new consoles you start will use it; websites and scheduled/always-on tasks will pick it up the next time they're started.   Right now it won't be used in Jupyter notebooks or in SSH sessions, though that will change in the future.
It won't harm or stop your current site -- its features are superset of the old virtualization system's.   We're planning to switch it on for everyone sometime over the coming month or two; the only reason we haven't done that yet is that we're testing how well it scales when there are thousands of people using it rather than just a few hundred.
              
Thanks for switching my account to new virtualization. 
Going to test it soon and then I will update if wkhtmltopdf is working fine or not.
Anyway, love the support here. I have seen responding you to Stackoverflow as well regarding Pythonanywhere.com questions.

Hi @nivas13897 sorry for the late response I did this a while ago so I'm not 100% sure what I did but if you give me a day or so I'll try to get back to you. What I can say is you will need the support team to switch your account to the virtualization system so that you can download it yourself. From what I can tell their latest system image isn't working properly or maybe I missed something.
              
Thanks for your valuable time and response @myles2. Sure take your time and let me know soon asap.,bcz i'm stucking with further development process.I hope don't need to download now already library is there in pythonanywere '/usr/bin/wkhtmltopdf' but i don't know the path , where is executable file for it to be configured in pdfkit??
In Local it works with : 
path_wkthmltopdf = b'C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe'
config = pdfkit.configuration(wkhtmltopdf=path_wkthmltopdf).
Similarly we need to know the executable file path in pythonanywhere??
Thanks in advance @myles2 and @suppor- pythonanywhere

I've switched on the new virtualization system for your account, so your code will use it in any new consoles; websites and scheduled/always-on tasks will pick it up the next time they're restarted.
If it still doesn't work, could you share the code you're using and any new error messages?

Unfortunately this script gets all from my app and needs to run automatically
[edit by admin: formatting]
              
wkhtmltopdf is installed in our latest system image, but it only works with our new virtualisation system. We can update both for you. Note that switching to the new system image may break some of your existing code that worked on older versions. You may need to recreate any virtualenvs that you're using and you will need to start new consoles and reload your web apps. You will also need to kill any ipython notebook processes that are running by using the "Fetch processes" button on the Consoles page.
              
I'm getting an error during the execution of pdfkit.

pdf = pdfkit.from_url(url, False, options=options)
response = HttpResponse(pdf,content_type='application/pdf')
response['Content-Disposition'] = 'attachment; filename="reportcard.pdf"
return response

wkhtmltopdf exited with non-zero code -6. error:

Locally I'm using this version of wkhtmltopdf, and it works fine:
wkhtmltopdf 0.12.6 
& on pythonanywhere the version is a bit older wkhtmltopdf 0.12.2.4.
I saw on stackoverflow upgrading to the latest version might work:
https://stackoverflow.com/a/51789478/8252429
Can you please upgrade the version?
              
My account previously got upgraded for new virtualization but I thought I will check it on the next site update but later due to COVID issue, I stopped my business so I had to shut down this website for few months and then I upgraded my account again.
So basically my account switched to basic like free account and then to $5 monthly plan.
I'm wondering if I still get the wkhtmltopdf automatically upgraded if not then please enable it for me as well.
              
Hi I am on the beginner account, and trying out pythonanywhere. I also have got as far as using the system /usr/bin/wkhtmltopdf, but end up with the error
wkhtmltopdf exited with non-zero code -6. error:
QXcbConnection: Could not connect to display
Is it possible to avoid this, or should I switch to weasyprint which I see is installed?
              
Thank you @fjl for confirming you saved my weekend by this quick response and @glenn + all devs for such an awesome update with this virtualization.
My app is running perfectly without any issue. Pythonanywhere supporting WKHTMLTOPDF perfectly. Awesome!!!!!!
              
i have run into the same problem with wkhtmltopdf on our eu.pythonanywhere.com account
unfortunately i can't login with the eu credentials for the forum :(
@fjl is there any chance you might change our eu account (controlaltcoop) to the new virtualization system so we can test if wktohtml works for us?
              
hi i am getting the error as 'OSError: wkhtmltopdf exited with non-zero code -11. error:'  have followed all the steps in this post and also from post "https://stackoverflow.com/questions/62783277/how-can-i-create-a-pdf-file-from-jinja-template-in-flask-question-tagged-pytho" can some one please help me.
              
Hello, please can this account be switched to the new virtualisation? I have a webapp pdf export function coded with pdfkit, which – no surprise now having read this thread – doesn’t work on PA. Thanks!
FWIW – I saw wkhtmltopdf was installed on PA so went ahead with pdfkit, having baulked at the dependencies of weasleyprint I’d need locally. Might be worth making a note on https://help.pythonanywhere.com/pages/PDF
Here’s the recipe that worked for me. First, in a bash console –
cat /etc/*release ← find out linux distribution, in this case Ubtuntu 16
wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.xenial_amd64.deb ← get the corresponding download from https://wkhtmltopdf.org/downloads.html
mkdir wkhtml-install ← create a directory to contain the wkhtml executable etc.
dpkg-deb -x wkhtmltox_0.12.6-1.xenial_amd64.deb wkhtml-install ← extract the download into the directory
Find the executable in there. Within that folder, it’s at usr/local/bin/wkhtmltopdf
Then, in the python web app code –
PDFKIT_CONFIGURATION = pdfkit.configuration() if settings.DEBUG else pdfkit.configuration(wkhtmltopdf='/home/<your user name>/wkhtml-install/usr/local/bin/wkhtmltopdf’)
Wherever you call pdfkit, add configuration=PDFKIT_CONFIGURATION
e.g. pdfkit.from_string(html, tempfile.name, configuration=PDFKIT_CONFIGURATION)
              
Hi @gleen, 
my application produces a PDF and I have this error:
OSError: wkhtmltopdf exited with non-zero code -6. error:
QXcbConnection: Could not connect to display 
I think it is the same problem of the other guys, can you turn on virtualization for my account too? 
Thank you very much!!
Virtualization was activated for my account for I'm still running into issues. 

I'm using django and django-wkhtmltopdf. PDF generation work fine on my local machine. This is the message in the logs when I access the view generating the PDF.
subprocess.CalledProcessError: Command '['/usr/bin/wkhtmltopdf', '--encoding', 'utf8', '/tmp/wkhtmltopdfmnz2jqo_.html', '-']' died with <Signals.SIGABRT: 6>.
From my virtualenv I ran this command :
wkhtmltopdf --encoding utf8 /tmp/wkhtmltopdfmnz2jqo_.html -
And got this error :
QXcbConnection: Could not connect to display 
Aborted
Any ideas on how to fix this issue ?
Thank you
              
Could you try adding this to the start of your script:
from pyvirtualdisplay import Display
...and then wrapping your call to generate the PDF inside a:
with Display():
...and see if that helps?
I managed to generate the PDF from the command line by running a small python script with the pyvirtualdisplay command :
with Display():
    os.system("wkhtmltopdf --encoding utf-8 /tmp/wkhtmltopdfii56luye.html -")
I'm now struggling to integrate the Display call with the django-wkhtmltopdf library. This is what a view looks like :
class MyPDF(PDFTemplateView):
    filename = 'my_pdf.pdf'
    template_name = 'template.html'
Any idea where the display command should go ? I tried to modify the render_to_response method but I get the same error message.
def render_to_response(self, context, **response_kwargs):
    with Display():
        response = super().render_to_response(context, **response_kwargs)
    return response
Thanks !

Hello,How do we know if the new virtualization is enabled for our account? If it isn't for mine, please enable it.
Thank you
              
Hi @hbconcepts. We're currently in the process of enabling the new virtualization system for all accounts on PythonAnywhere, which unfortunately may take a week or two to complete. We'll let you know when that has been done for your account; I've made a note to make sure that you're in one of the first batches to be moved over to it.

Hi @Finch4 -- we've enabled virtualization feature for you. Here are the next steps:
To use Chrome, you'll need to upgrade Selenium for your account -- for example, if you're using Python 3.7, run this in Bash:
pip3.7 install --user --upgrade selenium
...and then you can run Selenium with Chrome using code like this:
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
browser = webdriver.Chrome(options=chrome_options)
    browser.get("https://www.google.com")
    print("Page title was '{}'".format(browser.title))
finally:
    browser.quit()
              
But how to use it if I use wkhtmltopdf not directly by code below:
rendered = render_template('pdf/register_template.html', adres=adres,nazwa_usera=nazwa_usera,haslo=haslo)
    options = {"enable-local-file-access": None}
    pdf = pdfkit.from_string(rendered, False, configuration=config, options=options)
