  • I have installed Ubuntu 18.04 in my Lenovo laptop.

  • It does not show up the WiFi options.

  • I tried downloading the drivers and installing them in the way as described here Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE). But nothing in use.


  • Whenever i try to use make command, I get

  • The make command reports gcc is missing. If you want to compile the driver, install build-essential package.

  • Before going further, are you sure you have the exact same device? Even same models can come with different WiFi cards (and other parts, of course).

  • I suggest that you: sudo apt install libelf-dev and try again.

  • After installing build-essential also the problem exists with the error.

EDIT 2
- I have upgraded my kernel to 4.18.6 and also installed libelf-dev. Again when I enter make command. It gives

  • The make command reports gcc is missing. If you want to compile the driver, install build-essential package.

  • Before going further, are you sure you have the exact same device? Even same models can come with different WiFi cards (and other parts, of course).

  • I suggest that you: sudo apt install libelf-dev and try again.

            數位音樂下載 為非以「實體」方式來販賣音樂的相關產品，而使用數位格式如mp3、AAC等文件格式來進行銷售販賣的一种音乐产业形式。著名的數位音樂下載服務商有iTunes Store、RecoChoku、Google Play音乐和微软Zune等。数字音乐下载在二十一世纪初一度风靡全球， [1] [2] 使得传统唱片产业走向衰落，但其自身也在2010年代流媒体音乐服务如Apple Music、Spotify等的挤压下迅速失去市场份额。 [3] [4] 数字音乐下载有便于携带、传播迅速、制作简单成本低等优点，与流媒体音乐相比也能更好保障音乐人权益； [5] 但它同时很可能带来侵犯版权和滥用的情形， [6] 也给音乐产业带来了诸多不利影响。数字音乐下载为音乐人和乐迷提供了更加便捷直接的交流渠道，也一定程度上推动了网络音乐人的出现和独立音乐的迅速发展。 [7] 目录 1 历史 1.1 技术积淀（1987-2000） 1.2 出现与兴起（2000-2004） 1.3 唱片市场的颠覆者（2004-2007） 1.4 巅峰和衰落（2005-2013） 1.5 摇摇欲坠的现状与不可预知的明天（2014至今） 2 主要文件格式 2.1 PCM编码格式 2.1.1 WAV 2.1.2 APE 2.1.3 FLAC 2.2 苹果推出的无损文件格式 2.2.1 AIFF 2.2.2 ALAC 2.3 有损压缩格式 2.3.1 MP3 2.3.2 AAC 3 主要市场 3.1 iTunes Store 3.2 Google Play音乐商店 3.3 亚马逊音乐商店 3.4 部分其他音乐商店 4 影响与评价 4.1 对音乐产业的影响 4.2 对科技行业的影响 4.3 正面评价 4.4 负面评价 4.4.1 侵权问题 4.4.2 经营模式不明晰 4.4.3 不适应移动时代 4.5 文化现象 5 延伸阅读 6 参考资料 历史 苹果iTunes+iPod的软硬件搭配让数字音...
