Bug Description
Steps to reproduce:
- open update manager when a new ubuntu release is available
- click on "upgrade"
- wait for the downloading of packages to start
- while downloading packages, simulate a network failure by disconnecting the network and reconnecting
EXPECTED: an error message should appear with two options: Cancel, Retry
OBSERVED: you get an error dialog but there is no Retry option. You have to start all over again. This is ridiculous.
Downloading the whole upgrade can be a very long process and it is unacceptable to be unable to resume it if it is interrupted by even the smallest network failure.
To post a comment you must log in.
I know, all downloaded files are kept, so presumably, when you reestablish network connection and try again, you won't have to wait for all the files to download again.
HOWEVER you do have to go through the preliminary "calculating changes" stage, which takes forever.
So a "retry" option after a failure MUST be included.
