Troubleshooting

This guide is for troubleshooting application on Linux platforms.

Fail to launch the application

Since AppImage requires FUSE to work properly, you might see dlopen(): error loading libfuse.so.2 where some distributions does not come with FUSE library by default. For Ubuntu, Debian and their derivatives, here is the solution to make it works smoothly.
- Ubuntu (pre-22.04), Debian and their derivatives
  
  Be sure to check fuse3 does not exist. Manually install fuse2 by using the following command
```
    sudo apt-get install fuse libfuse2
```
- Ubuntu (>=22.04), Debian and their derivatives
  
  This is only valid with distributions having fuse3. Manually install fuse2 by using the following command
```
    sudo apt install libfuse2
```
  NOTE: Do not by any chance remove or purge fuse3 library which comes with the system. Many immportant packages depends on it, so you may end up completely crash your system.
