我的yocto系统当前正在运行旧的opkg version 0.2.2。无法安装某些软件包。出于测试目的，我尝试使用以下方法将opkg升级到opkg version 0.2.3，但也失败了-
root@cs15ka.99:/tmp# ls | grep opkg
opkg-0.2.3.tar.gz
root@cs15ka.99:/etc/opkg# ls
arch.conf base-feeds.conf opkg.conf
root@cs15ka.99:/etc/opkg# opkg install opkg-0.2.3.tar.gz
Unknown package 'opkg-0.2.3.tar.gz'.
Collected errors:
* opkg_install_cmd: Cannot install package opkg-0.2.3.tar.gz.
无论如何，我是否可以调整可能解决该问题的feeds或opkg文件？
feeds文件中没有任何内容。 opkg.conf看起来像这样-
# Must have one or more source entries of the form:
#
# src <src-name> <source-url>
#
# and one or more destination entries of the form:
#
# dest <dest-name> <target-path>
#
# where <src-name> and <dest-names> are identifiers that
# should match [a-zA-Z0-9._-]+, <source-url> should be a
# URL that points to a directory containing a Familiar
# Packages file, and <target-path> should be a directory
# that exists on the target system.

谢谢！
