After I do some basic processing, then export (and the box is checked to keep the exif data), the exif data is lost in the resulting created file.

?

I'm using Gimp 2.10.24 a Pentax k-s2 camera

p.s. The exif data is retained if I overwrite. It's just when exporting that it is lost... I can't do a "save as" because the resulting file is not jpg (it's .xcf)

When I saw thread title, "using a Pentax?"

You're not alone... https://docs.gimp.org/2.8/en/gimp-images-out.html

That was many months ago and was probably solved, but scrolling down to bottom, there's this link https://gitlab.gnome.org/GNOME/gimp/-/issues/7308

Perhaps report there?

After reading your reply, I thought and ask, are you a fellow Pentaxian?

I read through both url links you supplied. I will report the problem there also...

As of now, the only way to retain the EXIF data is to "overwrite" the original file after I have made my desired post processing adjustments (to the image)...

p.s. for the longest time, I was running the beta version of Gimp, with a flatpak installation (because exif data could not even be retained with the overwrite option of saving. Perhaps I'll install the beta version again and see how it behaves...

Sorry, no. Nikon user for decades...

But stumbled upon that exif report earlier in a completely unrelated websearch.

The internet is funny that way!

I wonder why you posted that link. I see no mention of losing EXIF data when exporting - except that GIMP should be compiled with EXIF support. Unlikely, but worth checking out I guess.
As OP did.
They already got a reply with a hint that should be followed up on:
Also standard troubleshooting techniques, like opening the application in a terminal to look for messages or cghecking various logs - all things this long-time LQ member has known for years.

I also wonder what "exif data is retained if I overwrite" means? Overwrite how? By exporting in GIMP?

Details...

I have seen confusion about exif vs IPTC and XMP. Sometimes the metadata is not really exif. So check those boxes too when you export, and see if it works.

A workaround is to use a tool like jhead to copy it from the orginal to the edited version. Like this:

Ha!... should've been https://gitlab.gnome.org/GNOME/gimp/-/issues/2253

Yeah, that one makes much more sense.
I hope OP sees it, reads it, and performs some tests.
It looks like the problem only occurs with JPEGs taken with the camera directly, and not raw images transformed to JPEGs.

That particular issue was closed 11 months ago, with 2 commits referencing it, but I couldn't figure out which GIMP release incorporated the changes.

I did some tests with one of the example images from that issue, and could not reproduce OP's problem (GIMP 2.10.28). However, exiftool outputs a much larger set of metadata (than exiv2), and it changes quite a bit after editing an image in GIMP - it's up to OP to delve deeper into that, and also take Guttorm's reply into account.
