Hey there, let’s work through this frustrating issue you’ve been stuck on for 3 days. The core problem here is that your Flatpak-installed VS Code (we can tell from the .var/app/com.visualstudio.code-oss paths in your log) can’t find the latexmk executable you installed via apt. Let’s break this down step by step:

Step 1: Find the actual path of your TeX Live tools #

Since you installed TeX Live and latexmk using apt (not the manual TeX Live download from the official site), their files aren’t in /usr/local/texlive—they’re in Debian’s default system directories. Run these commands to locate them:

• To find exactly where latexmk is installed:

  which latexmk
  

  For more detailed output, you can also use:

  dpkg -L latexmk | grep bin
  

  Normally, apt-installed latexmk lives in /usr/bin/latexmk, but let’s confirm that.

• Verify the path of other TeX tools (like pdflatex) to be sure:

  which pdflatex
  

  This should also point to /usr/bin if your apt installation worked correctly.

Step 2: Fix Flatpak VS Code’s sandbox access #

Flatpak apps run in a sandbox that limits access to system files by default. Even if latexmk is in /usr/bin, VS Code’s sandbox might not be able to see it. Here are two ways to fix this:

Option 1: Grant VS Code access to the system bin directory #

Open your terminal and run this command to let your Flatpak VS Code access /usr/bin (where your TeX tools live):

flatpak override com.visualstudio.code-oss --filesystem=/usr/bin

Restart VS Code after running this, then try compiling your .tex file again.

Option 2: Manually specify latexmk’s path in LaTeX Workshop settings #

If the sandbox override doesn’t work, you can directly tell LaTeX Workshop where to find latexmk:

1. Open VS Code and press Ctrl + , to open the Settings panel
2. Search for LaTeX Workshop > Tools > Latexmk: Path
3. Paste the full path you found in Step 1 (e.g., /usr/bin/latexmk) into this field
4. Save the settings, then restart VS Code and test your compile

Step 3: Double-check environment variables (if needed) #

If you still run into issues, you can manually add the TeX tools path to VS Code’s environment variables:

1. In VS Code Settings, search for LaTeX Workshop > Environment
2. Add a new entry with the key PATH and value /usr/bin:$PATH (replace /usr/bin with the path you found if it’s different)
3. Save and restart VS Code to apply the changes
