I searched the opendatahub-io/notebooks repo and could not find a file named jupyter/utils/install_texlive.sh on the main branch (no matching path in the repository tree). See the repository index. [1]

If you want, I can:

  • search other branches or tags for that file,
  • search the whole GitHub for copies of install_texlive.sh,
  • or open a specific branch/commit if you paste its name or URL.

<web_search_result>
I searched the opendatahub-io/notebooks repository and found no files or references named "install_texlive.sh". [1]

If you meant the script more generally, I found examples of an install_texlive.sh used outside the ODH repo (e.g., in container/Quarto setup instructions). [2]

Sources:

  • OpenDataHub notebooks repository (no matching file). [1]
  • Example use of install_texlive.sh in container/Quarto instructions. [2]

<web_search_result>
I searched the opendatahub-io/notebooks repository for "install_pandoc.sh" and found no files matching that name. (github.com)

Citations:

The Dockerfile references non-existent scripts that will cause the build to fail.

The pdf-builder stage (lines 17–18) attempts to copy install_texlive.sh and install_pandoc.sh from jupyter/utils/, but neither script exists in the repository. The Docker build will fail at the COPY instruction.

Verify:

  • Do these scripts exist in this PR branch (they are not in the main repository)?
  • If they should exist, create them or remove the COPY and RUN commands that reference them (lines 17–20).
  • If this stage is no longer needed, consider removing the entire pdf-builder stage (lines 9–27) and any downstream references to it.
🤖 Prompt for AI Agents 
In jupyter/minimal/ubi9-python-3.12/Dockerfile.cpu around lines 9 to 27 the
pdf-builder stage copies and runs jupyter/utils/install_texlive.sh and
jupyter/utils/install_pandoc.sh which do not exist and will break the build;
either add the missing scripts at jupyter/utils/ with executable permissions and
keep the COPY and RUN lines, or remove the COPY + RUN lines (lines 17–20) if
installing PDF tools is not required, or delete the entire pdf-builder stage
(lines 9–27) and any later FROM --from=pdf-builder references; ensure to
update/remove downstream references and confirm the PR branch contains the
scripts if you choose to add them.

site:github.com/opendatahub-io/notebooks pdf texlive pandoc install

<web_search_result>
Search results:

  • The opendatahub-io/notebooks repo itself has no bundled PDF build instructions — it’s a collection of notebook images and README only. [1]
  • Common solutions used in GitHub projects: (a) install pandoc plus a TeX distribution (TeX Live or BasicTeX) or (b) use a Docker image that bundles pandoc+TeXLive (e.g., pandoc-all-in-one). [2][3]
  • Useful minimal TeXLive package lists / scripts for Pandoc->PDF workflows are available (example gist showing required TeXLive packages). [4]

Quick recommendations (pick one):

  1. Linux (system packages)
  • Install pandoc and required TeX Live packages:
    • Debian/Ubuntu example:
      sudo apt-get update
      sudo apt-get install -y pandoc texlive-latex-base texlive-latex-extra texlive-fonts-recommended texlive-fonts-extra
      (This is the common approach used in many repos; adapt packages to needs). [4]
  1. macOS
  • Install pandoc via Homebrew/cabal and BasicTeX / MacTeX for pdflatex support (then use tlmgr to add missing packages). [4]
  1. Container / reproducible approach
  • Use a prebuilt Docker image containing pandoc + TeXLive (e.g., jakobkmar/pandoc-all-in-one or other pandoc/latex-derived images) and run pandoc inside the container (keeps notebook images small and reproducible). [2]

Notes / sources:

  • opendatahub-io/notebooks (repository searched). [1]
  • pandoc + TeXLive all-in-one Docker images (example: pandoc-all-in-one). [2]
  • Minimal TeXLive package lists / install scripts for pandoc -> PDF (example gists showing needed tlmgr/apt packages). [4]

If you want, I can:

  • produce an apt / yum / tlmgr install script tuned to your OS, or
  • prepare a Dockerfile that adds pandoc + the minimal TeXLive packages needed for PDF generation.

install_pdf_deps.sh does not exist in the repository, causing all non-ppc64le architecture builds to fail.

GitHub search confirms no .sh files exist in the jupyter/utils directory. The Dockerfile at lines 93–101 references ./utils/install_pdf_deps.sh as a fallback for non-ppc64le architectures (x86_64, aarch64, s390x), but this script is missing. The conditional will succeed only for ppc64le (which uses the cache mount); all other architectures will fail with "file not found" when attempting to execute the non-existent script.

Create jupyter/utils/install_pdf_deps.sh or update the Dockerfile to use an alternative approach for non-ppc64le systems.

In jupyter/minimal/ubi9-python-3.12/Dockerfile.cpu around lines 93 to 101 the
fallback references ./utils/install_pdf_deps.sh which does not exist and causes
non-ppc64le builds to fail; fix by either adding
jupyter/utils/install_pdf_deps.sh (make it executable) that installs the same
PDF dependencies as the ppc64le cached /pdf_builder (install texlive, pandoc and
any required packages and exit non-zero on failure), or update the Dockerfile to
replace the ./utils/install_pdf_deps.sh call with an inline set of installation
commands (or a different existing script) that perform the PDF dependency
installation for x86_64, aarch64 and s390x; ensure the chosen file/path is
present in the repo and referenced with the correct relative path in the
Dockerfile.

Add error handling and checksum verification for external dependencies.

Lines 16–17 install an external RPM and Pandoc package without verifying integrity or handling installation failures. If dnf install fails silently or the RPM is compromised, the build continues unchecked. Apply strict error checking and pin package versions or checksums:

dnf install on an external RPM and pandoc without integrity checks or robust
error handling; update the flow to (1) download the epel-release RPM to a
temporary file, (2) verify its checksum (and/or RPM GPG signature) against a
pinned value before installing, (3) install using dnf only if verification
succeeds, (4) pin the pandoc package/version (or install a specific released
RPM) and verify its checksum/signature as well, and (5) enable strict failure
behavior (e.g., set -e) and check dnf exit codes so the script exits with a
clear error message if any download, checksum verification, or install step

You seem to be adding a step that installs pandoc where previously it was not installed, and at the same you're adding a skip in a test that was previously checking for pandoc being present.

I'd expect you'd do one or the other, not both, tbh.

⚠️ Potential issue | 🟠 Major

Add checksum verification for all external downloads.

External downloads lack integrity verification, making builds non-reproducible and vulnerable to supply-chain risks. Downloads occur at:

  • Lines 21–30: CentOS RPMs (hardcoded URLs)
  • Line 33: TeX Live 2025 source archive
  • Line 55: TeX Live installer archive

Compute and verify SHA256 checksums immediately after each download:

   # Step 1: Download and extract the TeX Live source
-  wget https://ftp.math.utah.edu/pub/tex/historic/systems/texlive/2025/texlive-20250308-source.tar.xz
-  tar -xf texlive-20250308-source.tar.xz
+  TEXLIVE_SOURCE="texlive-20250308-source.tar.xz"

Apply the same pattern to the TeX Live installer (line 55) and consider pinning RPM package checksums or caching them locally.

Also applies to: 33-33, 55-55


# Step 1: Download and extract the TeX Live source

⚠️ Potential issue | 🟠 Major

Unsafe glob expansion for directory traversal.

Line 57 uses cd install-tl-2*/ which relies on glob expansion. If extraction fails, produces zero matches, or produces multiple matches, the glob silently expands unpredictably. Add explicit existence and uniqueness checks:

   wget https://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz
   tar -xzf install-tl-unx.tar.gz
-  cd install-tl-2*/
+  
+  # Find the extracted install-tl directory
+  INSTALL_TL_DIR=$(find . -maxdepth 1 -type d -name 'install-tl-*' | head -1)
+  if [[ -z "$INSTALL_TL_DIR" ]]; then
+    echo "Error: TeX Live installer directory not found after extraction"
+    exit 1
+  fi
+  cd "$INSTALL_TL_DIR"

In jupyter/utils/install_texlive.sh around lines 55 to 58, replace the unsafe
glob cd into install-tl-2*/ with explicit checks: after downloading and
extracting, verify tar succeeded, then list directories matching install-tl-2*
and ensure there is exactly one match (error and exit if zero or multiple),
assign that single directory to a variable and cd into that variable; this
prevents silent failures or ambiguous matches.
