`E: Unable to locate package elasticsearch` 오류는 Elasticsearch 패키지를 찾을 수 없다는 의미입니다. 이 문제는 보통 Elasticsearch의 공식 패키지 저장소를 추가하지 않았기 때문에 발생합니다. 다음 단계에 따라 Elasticsearch를 설치해보세요:

### 1. Elasticsearch GPG 키 추가
Elasticsearch 패키지의 무결성을 검증하기 위해 GPG 키를 추가합니다.
```bash
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
```

### 2. Elasticsearch 저장소 추가
Elasticsearch의 패키지 저장소를 추가합니다.
```bash
sudo sh -c 'echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" > /etc/apt/sources.list.d/elastic-7.x.list'
```

### 3. 패키지 목록 업데이트
패키지 목록을 업데이트합니다.
```bash
sudo apt-get update
```

### 4. Elasticsearch 설치
Elasticsearch를 설치합니다.
```bash
sudo apt-get install elasticsearch
```

### 5. Elasticsearch 시작 및 부팅 시 자동 시작 설정
Elasticsearch 서비스를 시작하고, 부팅 시 자동으로 시작되도록 설정합니다.
```bash
sudo systemctl start elasticsearch
sudo systemctl enable elasticsearch
```

### 6. Elasticsearch 상태 확인
Elasticsearch가 정상적으로 실행 중인지 확인합니다.
```bash
sudo systemctl status elasticsearch
```

이 과정을 통해 Elasticsearch를 성공적으로 설치하고 실행할 수 있습니다. 문제가 계속 발생하면, 오류 메시지를 확인하고 추가적인 문제 해결 단계를 시도해야 할 수 있습니다.

s****k@DESKTOP-1QGBFC1:~$ wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add - [sudo] password for siezetank: Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). OK

 

GPG 키가 성공적으로 추가되었습니다. "OK" 메시지는 키가 정상적으로 시스템에 추가되었음을 나타냅니다.

다음 단계로 넘어가세요:

1. Elasticsearch 저장소를 추가합니다:
   ```
   sudo sh -c 'echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" > /etc/apt/sources.list.d/elastic-7.x.list'
   ```

2. 패키지 목록을 업데이트합니다:
   ```
   sudo apt-get update
   ```

3. Elasticsearch를 설치합니다:
   ```
   sudo apt-get install elasticsearch
   ```

이 과정을 통해 Elasticsearch를 설치할 수 있을 것입니다. 설치 중 문제가 발생하면 알려주세요.
