I saw somewhere that I have to install libssl1.0-dev, but when I tried to give the command: sudo apt-get install libssl1.0-dev I got the error that this repository is missing. I found a page where I downloaded the .deb, but when I tried to install it, I got en error, that I already have the new version.
How to solve it?

Answer 1

pizzamonster is right.
Go here:
https://wkhtmltopdf.org/downloads.html
Download the 0.12.5 version for your operating system.
I'm using Mint 19 (ubuntu 18.04) so I'll keep going with that.
After you install the package, do:
which wkhtmltoimage
You'll probably get /usr/local/bin/wkhtmltoimage - so just copy this to a new place in your laravel project, in your case I'd make a new 'bin' directory, like this:
/var/www/botond/bin/
and then put wkhtmltoimage in that directory so you can commit it to your project.
Assuming you're using the snappy package by barryvdh (barryvdh/laravel-snappy), change your 'binary' attribute in your 'image' array (/config/snappy.php) to this:
'binary' => base_path('bin/wkhtmltoimage'),
or perhaps something like this:
'binary' => env('SNAPPY_IMG_BIN', base_path('bin/wkhtmltoimage')),
and you should be all set. You can, of course, also change binary to '/usr/local/bin/wkhtmltoimage' - or perhaps use this in your .env:
SNAPPY_PDF_BIN=/usr/local/bin/wkhtmltopdf
Good luck.
p.s. since you're doing this on Laravel, you might want to change the name of the question to 'wkhtmltoimage: QsslSocket Laravel barryvdh/laravel-snappy'

In my case (Debian buster 10.x) I need to update wkhtmltopdf binaries to newest one via composer. Unfortunately most common h4cc bins are abandoned. I prepare new updated one:
composer require getoxs/wkhtmltopdf-buster-amd64
