Error: Unhandled Exception: Unsupported R version 4.5.1 for operating system jammy.

Hi everyone,

I’d like to ask if there is any planned timeline for Shinyapps.io to support R version 4.5.1.

Currently, deploying apps built with R 4.5.1 results in the following error:

Error: Unhandled Exception: child_task=1560748236 child_task_status=error:
Unhandled Exception: Unsupported R version 4.5.1 for operating system jammy.

To get around this, I had to downgrade R to 4.3.2 and remove renv-related configuration, which breaks reproducibility across collaborators using newer environments.

I fully understand that aligning hosted environments takes time, but I’d really appreciate any update or roadmap info — even approximate — for when jammy + R 4.5.1 might be available in the Shinyapps.io infrastructure.

Thanks so much for all of your great work on Shiny,
Jakub

Hi
I'm not quite clear why it's taking so long for shinyapps.io to support the 4.5 series of R. I'm getting the same message, although the shinyapps.io states that new stable versions become available after 3 days. Workarounds include using Docker or Conda, but this involves multiple installations of R, associated packages for the shiny app etc. which isn't ideal. I'm going to wait and hope it becomes available soon.

I just encountered this issue on an enterprise shinyapps.io account. Adding a comment in hope of bumping this up the Posit priority list.

Hi Posit and shinyapps.io team please let us know when this will be resolved as it is affecting my ability to deploy apps for clients.

Also having the same issue. Commenting as well to get attention by the shinyapps.io account.

Just realised that this problem has also been highlighted at this thread in relation to R 4.5.0 and so obviously has been going on for some time. It's a little frustrating as we have an Enterprise shinyapps.io subscription, but I haven't managed to locate a timetable showing when the fix will be released.

After a few days of a similar failure message for R 4.5.0, last month I was able to deploy my Shiny app to the free instance of shinyapps.io. So the problem for that R version was, at least, addressed then. Since then I've updated my R instance to 4.5.1 and have the same experience that the others have reported. Did someone at Posit go on vacation and forget to leave the password?

Is there any other solution besides downgrading my R version? This is super frustrating. I have to contact my organization's IT every time I install R, and now I have to call them back and ask them to REINSTALL an OLD version of R.
