Quarto does not complete tinytex install on ubuntu

[melissa-barca]

We originally saw this issue in the IDE's automated builds, and I'm able to reproduce locally.

On ubuntu,quarto tools install tinytex does not properly install tinytex:

$ quarto tools install tinytex
Installing tinytex
[✓] Downloading TinyTex v2022.02
[✓] Unzipping TinyTeX-v2022.02.tar.gz
[✓] Moving files
[✓] Verifying tlgpg support
[✓] Default Repository: https://mirror.las.iastate.edu/tex-archive/systems/texlive/tlnet/
[✓] Updating paths
Installation successful

To complete this installation, please restart your system.

$ quarto tools
[✓] Reading Tool Data
Tool                Status                          Installed     Latest
tinytex             Not installed                   v2022.02      v2022.02

While there is a message instructing the user to restart their system, this doesn't fix the issue. Only after manually updating the PATH, does quarto finds tinytex:

$ PATH=$PATH:~/bin
$ quarto tools
[✓] Reading Tool Data
Tool                Status                          Installed     Latest
tinytex             Up to date                      v2022.02      v2022.02

On macOS, running quarto tools install tinytex works as I'd expect and quarto is able to find it immediately:

$ quarto tools install tinytex

I had a similar issue on Ubuntu with an error message about linking across file systems.

$ quarto -V
0.9.185
$ quarto tools install tinytex
Installing tinytex
[✓] Downloading TinyTex v2022.04.04
[✓] Unzipping TinyTeX-v2022.04.04.tar.gz
[✓] Moving files

Thanks for letting us know - the fix should be here:

A fresh release is being built now.

OK I've made a number of improvements to the installation and uninstallation. We now:

• Will try to find the best bin path to use for creating a symlink on the path (by checking the path)
• Will continue to install when symlink creation fails, but provide a user warning that provides commands to use to complete the installation (with the user providing the target bin path)
• Ensure that even with no symlinks, TinyTeX can be uninstalled
• Show warnings about incomplete installation when the user runs quarto tools to check status

In the CI case above, its possible that we will not be able to find a writable bin path, in which case you'll need to follow the instructions to point tinytex at a writable bin path.
