上周，我严格按照以下要求将我的 10.04 LTS 升级到了 12.04 LTS：关联（除了使用屏幕工具）并且升级成功。同样，当我尝试将另一个 10.04 LTS 升级到 12.04 LTS 时，我在 apt 更新/获取时收到错误，我无法复制粘贴屏幕上的所有内容，因为我正在直接连接机器而不是通过 ssh 进行升级，但仍然设法截取下面的屏幕截图，这就是它结束的地方：
以下是我的 sources.list 文件

答案1
apt-get如果您已将其配置为使用代理，并且代理配置错误，或者代理无法正常工作（例如无法访问互联网），将会报告错误。
/etc/apt/apt.conf检查您是否在或 中的某个文件中配置了代理/etc/apt/apt.conf.d。
从终端检查的一种方法是执行apt-config dump|grep -i proxy。
答案2
使用仅可通过 IPv6 地址访问的代理从 Ubuntu 20.04 升级到 22.04 时遇到此问题。
该问题是一个/usr/lib/python3/dist-packages/UpdateManager/Core/utils.py拒绝 IPv6http(s)_proxy设置的错误。
作为一种黑客解决方法，请仔细检查代理是否正确，并注释掉init_proxy函数中的以下几行：
# basic verification
#for proxy in proxies.values():
# if not re.match("https?://\\w+", proxy):
# print("proxy '%s' looks invalid" % proxy, file=sys.stderr)
# return
