Komodo and Dragon by Komodo install issue

[NathanRotta19]

Describe the bug

When attempting to install Komodo or Dragon by Komodo I from the add enging->Downloads page, a "no such file or directory (os error 2)" pop up appears.
I don't know if this is the issue but I noticed that this blob doesn't get expanded on the system call in strace:
readlink("/home/nathan/.local/share/org.encroissant.app/**", 0x7ffc50892560, 1023) = -1 ENOENT (No such file or directory)
despite the directory having files
ll ~/.local/share/org.encroissant.app/

Reproduction

I don't know what else other than attempting to install Komodo and Dragon by Komodo I.

Platform and versions

I used the en-croissant_0.15.0_amd64.deb to install. My operating system is Pop!_OS 24.04 LTS

You might have moved the engines folder, if not, you need to edit .json file of the engine, through en croissant application to the path where your .exe of the engine is present.. make sure you use exact symbol \ while specifying path while you edit .json in en croissant...

[NathanRotta19]

I did not move the engines folder. It defaults to ~/.local/share/org.encroissant.app/engines/. If I uninstall the app and delete the ~/.local/share/org.encroissant.app directory, it reappears there when I reinstall. Stockfish and Ruby download just fine but not either version of Komodo. I didn't want to find it online, download it, and install it under the "Local" tab because then the UI download feature would never be fixed. I did just look it up though and it appears Komodo is paid software. The solution may just be to remove it from the downloads tab if En Croissant does not integrate with the komodochess.com installer. If it is supposed to but it requires you to login komodochess.com, make the error reflect this.

There may be a problem with the .json file path, check it inside the en croissant application, I added LeelaChess0 engine manually with the icon by editing the .json files...

[neuroflowinfinix]

[NathanRotta19]

The problem is occurring on the add engine menu. The option to edit the json only appears after the engine has been added. I can't edit the json because it never gets downloaded. The problem I am talking about is from the Add Engine->Download menu.

[neuroflowinfinix]

Can you share a screenshot ?

Hope I can help you, since I have fixed many such errors... if you still get a problem, we'll edit the .json present inside the engines folder. (not through app, but through a text editor like notepad ++)
You can mail me at ujjwaldhote14@gmail.com

[NathanRotta19]

If I installed it some other way, the UI feature of the app would still have a download link that doesn't work. I wasn't looking for a work around. I was looking for a permanent fix to the desktop app for everyone who downloads it.

[neuroflowinfinix]

That could be the problem since you already installed it, the app is reading the folder, but cannot find the engine listed into engines.json , please check you file if that contains similar text...

The json file only includes engines that I have succesfully installed. If I remove an engine, It is removed from the json file automatically. If I add an engine, it is added to the json file, automatically. I have not edited the json file but I don't see anything suspicious about how its managed by the app. Komodo has never been added to the json file. The error appears before the json file is edited.

engines.json

[neuroflowinfinix]

If you have the engine folder containing the Dragon or Komodo, add it into .json, this will fix that, contact me on ujjwaldhote14@gmail.com , since it seems to be a local pc error and not software related

[NathanRotta19]

What do you mean its not software related? I doubt it is a hardware or even a firmware problem.

@NathanRotta19
With all due respect and humbleness, i only mean this is actually a local issue on your PC, not a bug in the current en-croissant release.
From your strace, the app is trying to do readlink on a path that ends with /** — this usually happens when the downloader finds leftover files or partial downloads from a previous manual attempt to install Komodo/Dragon.
Even if you think you never installed them before:

The app's downloader detects those partial/existing files in ~/.local/share/org.encroissant.app/ or in your Downloads folder.
It then fails to handle the path properly because it expects a clean state.

That's why other engines (Stockfish, etc.) install without any problem, and why a fresh reinstall of en-croissant alone doesn't fix it.

Quick things to try:

Completely delete the engines/ folder and engines.json inside ~/.local/share/org.encroissant.app/
Restart en-croissant and try downloading again... if this does not fix, i would request @franciscoBSalgueiro to help debug this...

[NathanRotta19]

On the before I reinstalled I recursively removed all subdirectories and files of ~/.local/share/org.encroissant.app as well as ~/.config/org.encroissant.app/ which includes the engines folder. It is not a problem with my filesystem or preexisting files in those directories. A partial file could result from it simply being slow to download.
