Is your copy of DaVinci Resolve 15 constantly crashing on startup after installation on a system running Ubuntu 18.04?

The problem may be related to several factors including conflicts with other applications or corrupted package files during the build process. In this article, we'll explore some troubleshooting tips and workarounds that can help you resolve these issues.

### Symptoms

When attempting to start DaVinci Resolve 15 after installing it using `makeresolvedeb15.0b6` on Ubuntu 18.04:

1. The application fails to launch or crashes immediately upon startup.

2. Error messages such as 'Segmentation fault' or 'Abnormal program termination' may appear in the terminal output.

### Cause

The most likely cause of this behavior is a conflict between DaVinci Resolve and another installed package on your system, particularly those related to video editing software like Shotcut, FFmpeg, etc., which can lead to conflicts during runtime.

To resolve these issues:

1. Uninstall all existing versions of DaVinance Resolve using `sudo apt remove --purge davinciresolve*` followed by a reboot.

2. Clean up residual files: Run `sudo rm -rf ~/.config/Resolve ~/.cache/Resolve`

3. Re-Install DaVinci Resolve 15 from scratch: Download and install the latest `.deb` package using an alternate mirror if needed (e.g., 'DaVinci Support Downloads'(https://support.apple.com/downloads)).

4. Reconfigure audio settings: Go to Preferences > Audio & I/O, then click on 'Reset' under both 'Input' and 'Output'.

5. If the problem persists after attempting all of above steps try re-installing `libavcodec-extra` library using `sudo apt install libavcodec-ffmpeg-extra56`.

If none of these suggestions resolve your issue please consider reaching out to either DaVinci Resolve Support Forum or seeking further assistance from a qualified video editing professional who may be able to provide more targeted advice specific to your particular setup.

Remember that keeping both system and software up-to-date is always recommended as newer versions often include bug fixes for known issues like this one.
