我是 Ubuntu 新手。我正在尝试将我的 Dell Latitude 7490 从 Ubuntu 18.04 更新到 20.04。
我试过：
sudo do-release-upgrade -d -f DistUpgradeViewGtk3
但我收到了这条消息：
Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Failed to connect: Connection refused
Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Failed to connect: Connection refused
/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeFetcher.py:23: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version ('Gtk', '3.0') before import to ensure that the right version gets loaded.
from gi.repository import Gtk, Gdk
之后我尝试：
sudo do-release-upgrade -d
我得到了：

我不知道该怎么办。我已经取消选中 livepatch 中的所有“其他软件”选项并重试，但不起作用。
我尝试替换所有来源列表，但还是不起作用。
如果有人能帮助我，我将非常感激。
PS. 我删除了https://代码中的所有内容，因为我收到一条消息说我的问题看起来像垃圾邮件
答案1
那如果没有 gtk (它是用来做什么的，GUI 升级程序吗？) 和 -d 呢？
sudo do-release-upgrade
背景 - 我们最近升级了 30 多台服务器和虚拟机，从 1604->1804->2004。最初我必须使用 -d 选项，但随着最近的升级，这不再是必需的。
