Ubuntu 19.04 で AppImage を開くことができません

Ubuntu 19.04 で AppImage を開くことができません

AppImagesをまったく開けないようです。"そのようなファイル、又はディレクトリはありません"奇妙に思えるエラー。

権限も正しく、新しくダウンロードした AppImage も起動しません。これが何を引き起こすのか、何か手がかりはありますか? ここに画像の説明を入力してください

更新1:
コメントで提案された Appimage でもう一度試してみましたが、残念ながら機能しません。少なくとも、問題は AppImage ではなく私のシステムにあることが説明されます。

最新のテストのコードは次のとおりです。

massigest@Laptop-Massi:~/Applications/Leafpad$ ls -l
total 768
-rwxrwxr-x 1 massigest massigest 786432 mei 22 15:28 Leafpad-0.8.17-x86_64.AppImage
massigest@Laptop-Massi:~/Applications/Leafpad$ ./Leafpad-0.8.17-x86_64.AppImage 
bash: ./Leafpad-0.8.17-x86_64.AppImage: No such file or directory

更新2:
注意: AppImage はどのディレクトリでも実行できません。また、Applications フォルダは私が所有しています。

他の非 AppImage アプリケーションはアプリケーション フォルダーで実行できます。以下にその例を追加しました。

massigest@Laptop-Massi:~/Applications/ArduinoIDE$ ls -l arduino
-rwxrwxr-x 1 massigest massigest 882 dec  6 11:24 arduino
massigest@Laptop-Massi:~/Applications/ArduinoIDE$ ./arduino
Picked up JAVA_TOOL_OPTIONS: 

また、 の出力に注意する必要があるというリクエストもありましたのでmount、以下を参照してください。
