Description Nate Graham 2018-02-10 16:16:14 UTC 
Discover from git master in KDE Neon.

Tried to install Chromium. It failed, with the following console message:

$ plasma-discover 
[...]

Manually running `sudo apt update` resolved the underlying issue, and then Discover was able to install Chromium. But that shouldn't have been required. Discover should be able to fix this situation on its own.
Comment 1 Aleix Pol 2018-02-12 18:09:30 UTC 
You mean that we should refresh and retry every time we find a ErrorPackageDownloadFailed?
Comment 2 Nate Graham 2018-02-12 18:12:14 UTC 
That would probably increase the reliability, and cut down on transient errors.

Pushed by apol into branch 'Plasma/5.12'.

PK: Make sure we don't use very outdated package dbs

If it's older than 1h, trigger a refresh.
