I had annotated a pdf in Okular that had been generated via pdflatex and saved it. I was able to open and see the annotations.
However, I guess I did a Ctrl-S on the tex file by mistake and that over-wrote the whole pdf and I've lost all my annotations.
Is there any way in which I can recover the annotations of my pdf?
I use Ubuntu 18.04 and Okular 1.7.2
