我正在将临时服务器更新到最新版本的 ubuntu。我遇到了一个无法弄清楚的错误……
当我跑步时
do-release-upgrade -d
我收到以下错误
ERROR:root:parse failed for ‘/var/lib/update-manager/meta-release-lts-development’
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/UpdateManager/Core/MetaRelease.py”, line 368, in download
self.parse()
File “/usr/lib/python3/dist-packages/UpdateManager/Core/MetaRelease.py”, line 239, in parse
while index_tag.step():
SystemError: E:Unable to parse package file (1)
Upgrades to the development release are only
available from the latest supported release.
有人知道如何解决这个问题吗？
更新：
我发现服务器正在寻找一个名为 的文件meta-release-lts-development，但该文件并不存在（只有meta-release-lts，其中只有官方版本）。不确定如何处理这些信息，但可能会有所帮助...
输出update-manager -c

如果do-release-upgrade失败，您可能需要编辑该release-updates文件。使用文本编辑器（例如 nano）打开该文件，
nano /etc/update-manager/release-upgrades
编辑最后一行：
Prompt=normal
然后运行do-release-upgrade（不带 -d 标志）
升级完成后，再次编辑该行以说明
Prompt=lts
