无法从 18.04 升级到 20.04 -“Ubuntu 未提供非官方软件包...”

  • 772

运行sudo do-release-upgrade时偶然发现错误：

An unresolvable problem occurred while calculating the upgrade. 

This was likely caused by: 
* Unofficial software packages not provided by Ubuntu 
Please use the tool 'ppa-purge' from the ppa-purge 
package to remove software from a Launchpad PPA and 
try the upgrade again. 

If none of this applies, then please report this bug using the 
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If 
you want to investigate this yourself the log files in 
'/var/log/dist-upgrade' will contain details about the upgrade. 
Specifically, look at 'main.log' and 'apt.log'.

我附上了 apt.log 和 main.log https://gist.github.com/omerbn/6e44593d8cab464be7f959b426d1c31c

接下来我该怎么办？

谢谢，

  1. Best Answer

    1. 安装 ppa-purge

      sudo apt install ppa-purge

    2. 在main.log定位有问题的包中：

      grep disabled /var/log/dist-upgrade/main.log

      输出示例：

      2021-03-19 02:44:31,173 DEBUG entry '# deb http://ppa.launchpad.net/kisak/kisak-mesa/ubuntu focal main # disabled on upg...

    3. 删除 ppa

      sudo ppa-purge kisak/kisak-mesa

  2. 我只是这样做解决了它：

    • 1.- 从软件和更新中禁用 ppa 存储库 > 其他软件

    • 2.- 清洁方便：

    sudo dpkg --configure -a
sudo apt clean
sudo apt update
    • 3.- 继续升级
    sudo do-release-upgrade

  3. 我遵循@Omeriko 当前接受的答案：安装 ppa-purge

    sudo apt install ppa-purge

    在 main.log 中找到有问题的包：

    grep disabled /var/log/dist-upgrade/main.log

    输出示例：

    2021-03-19 02:44:31,173 DEBUG entry '# deb http://ppa.launchpad.net/kisak/kisak-mesa/ubuntu focal main # disabled on upg...

    删除 ppa

    sudo ppa-purge kisak/kisak-mesa

    然后还有@Ecofintech的回答：

    sudo dpkg --configure -a
sudo apt clean
sudo apt update

    最后升级：

    sudo do-release-upgrade

    感谢两位为我的系统升级做出贡献的答案
