Tinytex: Installer does not respect proxy settings

Created on 30 May 2018 · 13Comments · Source: yihui/tinytex

It seems the installer is not passing the proxy settings from the R environment. I have the http_proxy environment variable set, but the texlive installer does not see it. I'm not sure if this is an issue with tinytex or texlive itself. I get to this point in the install process:

Starting to install TinyTeX to T:\R\tinytex. It will take a few minutes.
PATH=...
"C:\Users\AppData\Local\Temp\1\Rtmpwrvk7m\install-tl-20180530\install-tl" -profile=../texlive.profile
Automated TeX Live installation using profile: ../texlive.profile
Loading http://mirrors.ibiblio.org/pub/mirrors/CTAN/systems/texlive/tlnet/tlpkg/texlive.tlpdb
First directive needs to be 'name', not <HEAD><TITLE>Authentication Required</TITLE></HEAD> at C:/Users/AppData/Local/Temp/1/Rtmpwrvk7m/install-tl-20180530/tlpkg/TeXLive/TLPOBJ.pm line 104, <$retfh> line 1.

You can see the message from my proxy server saying "Authentication Required".

Here is a prebuilt version (daily build) of TinyTeX for Windows: https://ci.appveyor.com/api/projects/yihui/tinytex/artifacts/TinyTeX.zip If you devtools::install_github('yihui/tinytex'), you can install it via tinytex:::install_prebuilt(). Per FAQ 2, I don't really want to publicize this feature, so it is an internal function.

I have no idea. From https://www.tug.org/texlive/acquire-netinstall.html

If you need to download through proxies, use a ~/.wgetrc file or environment variables with the proxy settings for wget. TeX Live always uses GNU wget to download.

It seems that setting the environment variable http_proxy should work, but the texlive installer didn't inherit the environment variable for some reason. I'm afraid you will have to debug this by yourself, since I don't really use Windows or proxy. I'm not sure if ~/.wgetrc would work.

I think something must have changed in TeXLive, since it has worked for me in the past and my settings have not changed. I'll try a few things.

Yeah that is likely. I know they have messed around with the downloaders (such as wget) in the installer, but I don't know what exactly they did.

So it worked to set the following line in ~/.wgetrc (which is C:\Documents\.wgetrc on windows):

http_proxy=127.0.0.1:8118

Perfect. Thanks for posting back!

Looks like the install did not actually finish, something strange is going on here.

I have no idea what this error message means. I just tried it on AppVeyor and it seems to work fine: https://ci.appveyor.com/project/yihui/tinytex/build/1.0.26

yihui on 31 May 2018

Ugh this is frustrating, can't stand working on windows. Seems this may still be an issue with the proxy. I get the proxy error when trying to re-install, looks like the math.washington.edu mirror seems to partially work but no other mirrors do.

If you can succeed on at least one Windows machine, you can copy the installed folder to another Windows machine and set PATH appropriately.

yihui on 31 May 2018

That would be amazing, unfortunately I don't have access to any other windows machine. Could that be something that was provided as a "build" on github? I'm sure others would find it useful too.

cameronbracken on 1 Jun 2018

That is entirely possible, but I don't have time for it. Here are some tips for whoever wants to implement it:

Use Travis CI to build TinyTeX (TeX Live) on Ubuntu and macOS, and use AppVeyor for Windows.
After it is built and installed, zip up the folder, and upload it somewhere. Personally I don't want to provide a permanent download, so I'd use file.io, like what I did in the travis-exitwp repo: https://github.com/yihui/travis-exitwp Then if a user wants to build TinyTeX on the cloud, he/she can fork this repo and set up Travis/AppVeyor. An alternative to file.io is to use the Travis cache or AppVeyor artifacts.
