系统信息显示 Mint,但已安装 Ubuntu 21.10 -> 无法升级到 22.04

不久前我全新安装了 21.10,今天我想升级到 22.04。

但是,我已经通过 Mint 存储库安装了 Chromium,因为它不再位于 Ubuntu 存储库中。之后,我的系统信息告诉我,我正在运行 Mint 20.3,但事实并非如此。

lsb_release -a 说:

No LSB modules are available.
Distributor ID: Linuxmint
Description:    Linux Mint 20.3
Release:    20.3
Codename:   una

cat /etc/*-release 的输出显示:

DISTRIB_ID=LinuxMint

apt-cache policy base-files 的输出是:

cat /var/log/installer/media-info 告诉我:

Ubuntu 21.10 "Impish Indri" - Release amd64 (20211012)

这正是我安装的!所以我运行的是 21.10,但 Chromium 安装“劫持”了我的系统,并告诉我我使用的是 Mint 20.3

当我尝试的时候

sudo do-release-upgrade -d

但未能成功:

“Ubuntu 的新发布版本将在开发版本中搜索更新,但只能从最简单的版本开始。”

(抱歉,我是用德语系统,希望它能让我理解它所告诉我的内容。基本上:不会让你将 Mint 更新到 Ubuntu)

我已经尝试清除 Chromium,但没有成功。

那么,我该怎么做才能将系统升级到 22.04,而无需重新安装?我如何才能“摆脱”错误的系统解释?

答案1

成功了!强制“基础文件”使用 impish 存储库作为源,一切恢复正常。双启动 GRUB 屏幕仍然显示它是 Mint,但系统升级后就消失了。谢谢!
