Hi all. Some of my older edits on tiff files are showing messed up, and suspect #1 is 5.2.1. I’d like to open them with 5.2.0 without uninstalling 5.2.1. What’s the recommended way to have an older version “on the side”? My system is Ubuntu 24.04. Thx!
This has been discussed (in the context of newer or test versions) many times, and is also described in the user manual. Check the command-line arguments for config and cache directory.
How about trying to figure out why they are messed up? Maybe post a tiff + xmp for others to help find the issue.
Thanks for the response and sorry for the lack of clarity. I’m aware of the command-line options I have to use. The subject of this post should have been “how to install” not “how to run” (an older version, without uninstalling the current one). I did not find any pointers.
Instructions for running two versions side-by-side are included in the github README
Okay, thanks all, I’m back in business. First darktable 5.2.1 wasn’t opening my tiff files because of [imageio] Avoid reading TIFF files made from raw as raw format by victoryforce · Pull Request #19189 · darktable-org/darktable · GitHub. That part was fine with 5.2.0.
exiv2 -M"del Exif.Image.Make" file.tiff
took care of that.
But then one my tiff.xmp files was missing all my masks. I have no idea how that could have happened, but by looking at my versioned backups I’m seeing it ocurred before I installed 5.2.1. I restored a good version of that sidecar and all is good now.
(versioned backups rock, by the way!
