add-apt-repository 抛出 Python 错误：UnicodeDecodeError：'ascii' 编解码器无法解码字节 0xc5

Question

尝试安装最新的 PHP5 软件包，因此我添加了我需要的 repo ( sudo add-apt-repository ppa:ondrej/php5 )，结果如下：

    Traceback (most recent call last):
  File "/usr/lib/python3.2/threading.py", line 740, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3/dist-packages/softwareproperties/ppa.py", line 141, in run
    self.add_ppa_signing_key(self.ppa_path)
  File "/usr/lib/python3/dist-packages/softwareproperties/ppa.py", line 234, in add_ppa_signing_key

    got_fingerprints = self._get_fingerprints(keyring, keyring_dir)
  File "/usr/lib/python3/dist-packages/softwareproperties/ppa.py", line 178, in _get_fingerprints
    output = subprocess.check_output(cmd, universal_newlines=True)
  File "/usr/lib/python3.2/subprocess.py", line 516, in check_output
    output, unused_err = process.communicate()

    stdout = _eintr_retry_call(self.stdout.read)

    return func(*args)
  File "/usr/lib/python3.2/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 92: ordinal not in range(128)

在 Ubuntu 12.04 服务器上运行

Answer 1

software-properties-common 有问题，所以如果有时间，请将其报告为 software-properties-common 中的错误。

在添加存储库时使用特定 unicode 语言环境的问题跟踪器中指出了一个更好的解决方法

LC_ALL=C.UTF-8 add-apt-repository -y ppa:ondrej/php5-5.6

Answer 2

尝试安装一个可以纠正编码问题的语言包，例如

sudo apt-get install language-pack-en

这将为所有支持的包（包括 Python）提供英文翻译数据更新。

请参阅：UnicodeEncodeError: 'ascii' codec can't encode character。

否则手动设置区域设置，例如

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8
