我收到这个错误:

我尝试了 --no-check-certificate 方法，但没有任何区别。

在该页面上向下滚动，第一个要点:

sudo -v &&
    wget --no-check-certificate -nv -O- https://raw.githubusercontent.com/kovidgoyal/calibre/master/setup/linux-installer.py |
    sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"
