Heroku Cedar-14和libjpeg.so.62

Question

After upgrading a production application on Heroku to cedar-14, I am running into issues with carrierwave-video-thumbnailer . In particular, I get the error:

ffmpegthumbnailer: error while loading shared libraries: libjpeg.so.62: cannot open shared object file: No such file or directory

After looking into this, I found that other people are having issues with libjpeg after upgrading to cedar-14 (for other gems besides ffmpegthumbnailer)

My questions are:

1. Is there a way to fix this?, or otherwise
2. How can I revert back to cedar-10?

(I tried heroku stack:set cedar-10 but get the error resource not found )

Answer 1

You only have a limited time left on cedar-10, so you'd do well to try to fix the issue. However, if you need to revert it temporarily, read on.

heroku stack:set cedar doesn't seem to be working anymore, probably because it is a ticking time bomb.

To rollback, you can use the heroku rollback functionality.

1. First, get the version number of the most recent release before you upgraded.

   heroku releases

2. Then, do:

   heroku rollback v65

   (using the version you identified from the previous step instead of v65)

Good luck!
