sudo swapoff -a그런 다음 이전 프로세스를 실행 하고 다시 시도했는데 이제 이 오류가 다시 발생합니다.

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`
To see the stack trace of this error execute with --v=5 or higher
그리고 나는 도커가 실행되고 있는지 전혀 모릅니다. 어떤 해결책이라도 도와주실 수 있나요? 정확히 문제가 무엇인가요?
