升级到Ubuntu 20.04

Question

我正在尝试从Ubuntu18.04.5升级到Ubuntu20.04。在apt update & apt upgrade之后，我想

do-release-upgrade

我得到以下错误：

    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.

我看到我以前安装了ppa:ubuntu-toolchain-r/test和ppa:hanipouspilot/rtlwifi，这导致了这个问题。

因此，我试图清除它们，但得到以下错误：

root@ubuntu:~# ppa-purge ppa:ubuntu-toolchain-r/test
Updating packages lists
E: Failed to fetch http://ppa.launchpad.net/hanipouspilot/rtlwifi/ubuntu/dists/bionic/InRelease  403  Forbidden [IP: 91.189.95.83 80]
E: The repository 'http://ppa.launchpad.net/hanipouspilot/rtlwifi/ubuntu bionic InRelease' is not signed.

看起来，由于服务器不再可用，清除失败了吗？

如何手动删除包？

Answer 1

在从18.04 LTS升级到20.04 LTS时，我也遇到了类似的问题。

我不得不删除/var/log/dist-upgrade/[CURRENT_DATE]/apt.log中列出的坏包

列出破碎的包裹：

grep Broken /var/log/dist-upgrade/[CURRENT_DATE]/apt.log

然后取出每一个破损的包裹：

apt remove gsettings-desktop-schemas mutter gir1.2-mutter-6

可能需要删除其他依赖于这些包的包。

Answer 2

答案是：从18.04升级到20.04，因为“E:Error，pkgProblemResolver：：解决生成的中断，这可能是由持有的包引起的.”

这个问题可能与喃喃自语的尝试无关。

sudo apt remove python2.7-minimal和sudo apt autoremove

这实际上解决了我的问题。
