I have read throught the discussion posts and I am getting really frustrated. My InDesign document will not package - getting that cannot link error. Checked and tested the profile, the images do not have odd characters in them and the images are in CC Libraries - nothing is working.
Rollback to a previous InDeisgn version

I ended up trying that and it still did not work. I sent through some files to my printer who was able to check in pre-press to troubleshoot. The issue was that the images were linked to CC Libraries ( I think there was some update to that recently). When I linked to the same images saved on the PC desktop I was able to successfully package as it "embeds" the images and exports links into the package. I did not try linking to my creative cloud offline files so will attempt that next time but it was many hours of frustration for what has been a simple task previously. My printed magazine is now in production thank goodness.
