repository keys expired

[paultopia]

Hi there,

I had integrated this script into my netlify build process until just recently, when, all of a sudden, the build process started failing with:

12:36:50 PM: [build.sh] Installing TeX Live...
12:36:51 PM: Automated TeX Live installation using profile: /dev/fd/63
12:36:53 PM: Loading http://mirrors.ibiblio.org/pub/mirrors/CTAN/systems/texlive/tlnet/tlpkg/texlive.tlpdb
12:36:54 PM: install-tl-20191006/install-tl: unexpected return value from verify_checksum: -5

After doing some investigation, this seems to be happening because the keys for either tlcontrib or the main texlive repository, or both, have expired. See this SO and also this one.

but the fixes and workarounds for these all seem to rely on tlmgr being used, whereas this seems to be happening inside the install-tl script --- I think before tlmgr gets installed? So I'm guessing that install-tl needs to be updated.

Update: after replacing the existing install-tl-unx.tar.gz with the one downloaded from here, the build process still fails with:

The same error occurs if I go through the build.sh file and replace every reference to 2019 with 2020. And it also occurs if I clear the netlify cache and re-deploy.

Ok, second update! I think I have a fix. I guess the 2020 installer doesn't want the contents of the installation profile passed to it as a string? Before calling the installer script, I stuck in a

echo "$TEXLIVE_PROFILE" > texlive.profile

and then changed the line in build.sh that calls it to

"$INSTALL_TL_VERSION"/install-tl --profile=texlive.profile

and that seems to have gotten it going.

So, in summary, steps to fix:

1. swap out the old installer for the new one.

2. change every reference in build.sh from 2019 to 2020.

3. change the texlive profile from a string passed to the installer via echo to a file.

4. Just to be on the safe side, stick a --verify-repo=none into every call to tlmgr (as suggested by one of the linked SOs from the first comment in this issue)

and things are working again.

Thanks for looking into this! Can you submit a PR?

Regarding --verify-repo=none, I haven't thought about the implications of this but it may not be a good idea.

[paultopia]

Sure thing, I'll put together a PR in a bit, and also figure out whether it works without --verify-repo=none
