Doesn't work with Ubuntu 22.04

[msrd0]

I'm using inkscape to convert svg to tex so I need Ubuntu 22.04 for a recent inkscape version in CI. However, tectonic then fails to run with error message

tectonic myfile.tex
dlopen(): error loading libfuse.so.2

AppImages require FUSE to run. 
You might still be able to extract the contents of this AppImage 
if you run it with the --appimage-extract option. 
See https://github.com/AppImage/AppImageKit/wiki/FUSE 
for more information
make: *** [Makefile:28: myfile.pdf] Error 1

Hi @msrd0

Thanks for reporting the issue.
This is an upstream issue of AppImage (AppImage/AppImageKit#1120 AppImage/AppImageKit#877) / Ubuntu 22.04 (Bug 1965636 marked as wont fixed in Ubuntu) .

Have you tried installing libfuse like described in the link?
e.g.

sudo add-apt-repository universe
sudo apt install libfuse2

Probably this will be fixed upstream in AppImage with this issue AppImage/AppImageKit#877

EDIT: I tested the workaround on a sample repo and it seems to work.
See here https://github.com/WtfJoke/setup-tectonic-sample/blob/ubuntu2204/.github/workflows/push.yml#L9-L12

Yes the workaround works. Unfortunately I'm stuck with texlive (which takes forever to install) since tectonic doesn't support pstricks which is what inkscape outputs.

EDIT: if anyone else needs to use texlive in CI, I highly recommend using jirutka/setup-alpine and apk add texlive-xetex texlive-texmf-most. This completes in about a minute, compared to the 15 minutes it takes ubuntu to install those same packages with an already installed os.

Yes the workaround works.

Thats a bummer :S but glad it worked out with the alpine package

Hey @msrd0
FYI: I've added support for Ubuntu 22.04 now (I've switched from AppImage to the regular binary on newer tectonic versions).
You can test it if you want/can:

steps:
  - uses: wtfjoke/setup-tectonic@v2
    with:
      github-token: ${{ secrets.GITHUB_TOKEN }}
  - run: tectonic main.tex
