Please help me
Thanks and Regards

try to run this command maybe it work

sudo apt-get install xvfb libfontconfig wkhtmltopdf

I ran this command

You can try:
$ sudo bench install --help

It should show an option to install wkhtmltopdf.
From a hint from Gavin at a “random” place in the forums from some years ago, I found this.
Try to get to the intended result in another way … good luck (searching for the qt patched package on certain websites, which don’t even seem to hold it, etc.).

So that bench install command shown in bench’s --help option when run as superuser is the only one which worked and works for me, resulting in this:

~/frappe/dev-bench$ wkhtmltopdf --version
wkhtmltopdf 0.12.6.1 (with patched qt)

Why is that?
It’s running ansible playbooks integrated in bench. These seem to be the ones which are used by Frappe Cloud and the images it builds for it to run. So this is something the Frappe Uber-Admins give a lot of attention to, so it works well, once the prerequisites are there.
You also can learn many intricacies from these playbooks included in the bench’s code if you read them very attentively.

But you first must uninstall other versions of wkhtmltopdf which might have been installed in another way.
Also, for this to work, and even to show up in the --help, the bench must be run as superuser (e.g. sudo).
I noticed that I even had to install another bench as superuser before that, because the normal bench didn’t run as superuser at all, although I can do any other normal admin task with it.
You also need ansible for this to run, of course. From the environment of the bench, it’s “pip install ansible” or so, maybe you need to run this as sudo, too, I don’t remember exactly.
I didn’t really understand this sudo/non-sudo bench dichotomy for now, any hints are welcome.

Hi bro

I ran the following command and got an error and don’t know how to fix i
