PlusMinus, I sent an email explaining how to download the file via console, I hope it helps. Basically I passed through the WGET command the parameters that are passed by the form of the download site. Follow the URL wget --user-agent=Mozilla/5.0 --save-cookies cookies.txt --post-data 'fileId=993&accept_submit=Accept' --no-check-certificate http://www.displaylink.com/downloads/file?id=993 -O new_filename.zip It is not possible to use the URL (http: //assets.displaylink.com/live/downloads/ ...) as the @chico mentioned, because it has an expiration parameter. This parameter is concatenated with authentication data, so there is no possibility of change.

Well, the download link gives an invalid zip file due to an authentication mechanism. I had to download the file manually, get the checksum and modify the PKGBUILD file accordingly. I've tried to get a valid download link but I fail to authenticate. By spying on the http headers I found out the URL (including the authentication data.) ------------------------------------------------------------------------- [chico@inti ~]$ wget http://assets.displaylink.com/live/downloads/software/f993_DisplayLink%20USB%20Graphics%20Software%20for%20Ubuntu%201.3.54.zip?AWSAccessKeyId=AKIAJHGQWPVXWHEDJUEA&Expires=1499078247&Signature=Im%2Bth5wbf75M12tXTx1iD0CL8%2FY%3D [1] 28968 [2] 28969 [chico@inti ~]$ Redirecting output to ‘wget-log.1’. ^C [1]- Exit 8 wget http://assets.displaylink.com/live/downloads/software/f993_DisplayLink%20USB%20Graphics%20Software%20for%20Ubuntu%201.3.54.zip?AWSAccessKeyId=AKIAJHGQWPVXWHEDJUEA [2]+ Done Expires=1499078247 [chico@inti ~]$ cat wget-log.1 --2017-07-03 12:28:46-- http://assets.displaylink.com/live/downloads/software/f993_DisplayLink%20USB%20Graphics%20Software%20for%20Ubuntu%201.3.54.zip?AWSAccessKeyId=AKIAJHGQWPVXWHEDJUEA Resolving assets.displaylink.com... 52.218.48.148 Connecting to assets.displaylink.com|52.218.48.148|:80... connected.

Yeah, saw that yesterday as well. I just don‘t know yet how to get the file since they changed their download mechanism to JS. :-/

Thanks adamgomes, your fix worked for me - " if you modify the PKGBUILD file in the evdi package so that you are using 1.4.1, it will compile w/ 4.11.1 through 4.11.3 on Line 4: pkgver=1.4.1 on Line 23: md5sums=('eece77058251418d5707457aa8ae914e') Then you can re-build this package. "

I dug into it a bit. The accept page now uses JS (I am really starting to hate web developers) to initiate the download, and the download function is buried in one of the several imported javascript files. I haven't located it yet, but if I do I'll let you know. Any way I can manually download the file and stick it somewhere for yaourt to find? I have never been very successful with getting pkgbuild to play nice with kernel modules.

This package now fails because DisplayLink changed the download process. What gets downloaded now is the DisplayLink terms of agreement web page, not the zip archive. $ file /tmp/yaourt-tmp-${USER}/aur-displaylink/displaylink-driver-1.3.52.zip /tmp/yaourt-tmp-ser/aur-displaylink/displaylink-driver-1.3.52.zip: HTML document, ASCII text, with very long lines, with CRLF, LF line terminators ==> Retrieving sources... -> Downloading displaylink-driver-1.3.52.zip... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 23043 100 23043 0 0 39029 0 --:--:-- --:--:-- --:--:-- 38989 -> Found udev.sh -> Found 99-displaylink.rules -> Found displaylink.service -> Found displaylink-sleep.sh ==> Validating source files with md5sums... displaylink-driver-1.3.52.zip ...
