终端抛出某些安装错误消息

Question

每当我打开终端时，它都会显示以下不必要的消息：

有人能解释一下如何消除此消息吗？

以下是我的 ~/.profile 和 ~/.bashrc 文件：

轮廓：

  . /etc/bash.bashrc
fi
else
if [ "`id -u`" -eq 0 ]; then
  PS1='# '
else
  PS1='$ '
fi
fi
fi

# The default umask is now handled by pam_umask.
# See pam_umask(8) and /etc/login.defs.

if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -r $i ]; then
  . $i
fi
done
unset i
fi 

.bashrc：

# this file has to be sourced in /etc/profile.
