Failure to show thumbnails with image-dired

I was trying to view images in emacs, and it works fine as expected. The problem came when I tried to view thumbnails with image-dired. Whenever I try to use `M-x thumbs` I get `thumbs-call-convert: Searching for program: No such file or directory, /usr/X11R6/bin/convert`, whenever I try to use `image-dired` from whitin `dired` I get `image-diredx--invoke-process: Wrong type argument: processp, [nil 25355 43307 399593 nil image-dired-thumb-queue-run nil nil 110000]` and when I call `image-dired` alone I get `Error running timer ‘image-dired-thumb-queue-run’: (error "Executable image-dired-cmd-create-thumbnail-program not found")` I scrolled through documentation in the wiki and I thought that I had a problem with Image magick, so I installed, but as you have read, It tries to read to executable from a release of Xorg that is 26 years old. I'm a little lost here, I've scrolled through all the posts with "thumb" in various forums a good part of them mostly apply to compile time shenanigans (ruled out because I can see images with dired and pressing 'v' or Windows with the image magick support (and I'm on Debian). Thanks. SOLVED!: I had problems with `image-dired+`, an unsupported package that is still in melpa for reasons... It may have installed as dependency with some other package or may have forgotten when I installed it (probably the later). Simply deleting the walking corpse of a package solved all my problems.

`thumbs-conversion-program` is what `thumbs-call-convert` uses, is that set to something wacky? Is `/usr/X11R6/bin` in your `$PATH`? It doesn't do thumbnails, but you might consider my [Dired Image Slideshow](https://codeberg.org/emacs-weirdware/diss) (diss) package. I made it because I tried every other slideshow thing for Emacs and didn't think any of them were much good.

It is not, I know that Debian uses a ten year old kernel (at least :)), but there is not a single piece of code in my dependencies that requires that directory (except `thumbs`).

I don't use this feature but I just tested and it works. I'm using current Debian stable with the packaged emacs. Digging in the source of `thumbs`, it uses a variable called `thumbs-conversion-program`, which is defined as `(or (executable-find "convert") "/usr/X11R6/bin/convert")`. I do have a `convert` program. It appears to come with the Debian package `imagemagick-6.q16`. Can you invoke the `convert` program in the terminal? If no, you might have to fix that. If yes, did you try to restart emacs after installing imagemagick?

I had installed imagemagick from the appimage, but with the packaged debian binary `thumbs` works perfectly, but `image-dired` still has the same errors.

Thats weird. `image-dired-cmd-create-thumbnail-program` has the value defined as `convert`, so it should behave the same as `thumbs`. Are you sure its the same error? > and when I call image-dired alone I get > Error running timer ‘image-dired-thumb-queue-run’: (error Executable image-dired-cmd-create-thumbnail-program not found")

Rookie mistake, I copy and pasted in the wrong order, I actually got `image-diredx--invoke-process: Wrong type argument: processp, [nil 25356 6317 371427 nil image-dired-thumb-queue-run nil nil 637000]`

It seems you are using an external package. Try to use `image-dired` without loading your init-file (`emacs -q`). This `image-diredx--invoke-process` function appears to come from the `image-dired+` package. I'm only a beginner in elisp, but this line is very suspicious: https://github.com/mhayashi1120/Emacs-image-diredx/blob/b68094625d963056ad64e0e44af0e2266b2eadc7/image-dired%2B.el#L159 I can only guess that this worked before but emacs has since changed something and this no longer works. The package author no longer maintains this code.

And it works just fine, it was the `image-dired+` that was giving me trouble, I don't even remember installing it lol. I think that by installing, emacs linked it to `image-dired` proper, giving me all the headaches that software that requires necromancy to work always comes with. Thanks for the help :^).
