我想更新我的ubuntu服务器版本
我执行命令sudo apt-get update，一切似乎都很顺利，但当我运行sudo apt-get upgrade时，出现了这个错误，有人可以帮助我吗？

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "en_US:en",
LC_ALL = "en_US.UTF-8",
LC_TYPE = "en_US.UTF-8",
LANG = "en_US.UTF-8"
are supported and installed on your system.

dpkg: warning: 'ldconfig' not found in PATH or not executable
dpkg: error: 1 expected program not found in PATH or not executable
Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin
E: Sub-process /usr/bin/dpkg returned an error code (2)
由于该错误，ldconfig可能已从libc6移动到libc-bin。使用以下命令下载并提取libc-bin包：
apt-get download libc-bin
dpkg -x libc-bin*.deb unpackdir/
接下来你需要复制这些文件：
sudo cp unpackdir/sbin/ldconfig /sbin/
现在你需要确保一切正常。运行这些命令以确保：
sudo apt-get install --reinstall libc-bin
sudo apt-get install -f
答案来自修复：无法执行"locale"：在/usr/share/perl5/Debconf/Encoding.pm 中没有这样的文件或目录
