Bug Description
command:sudo do-release-upgrade
正在计算变更
正在计算变更
无法计算升级
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.
如果这些都不生效,请在终端中使用命令 'ubuntu-bug ubuntu-
bug。If you want to investigate this yourself the log files in
'/var/log/
Specifically, look at 'main.log' and 'apt.log'.
