Data from Ubuntu 12.10 + 13.04 is not present

[Matthew Paul Thomas]

1. Go to <https://errors.ubuntu.com/>.
2. Set "Showing error reports from release" to "Ubuntu 12.10" or "Ubuntu 13.04".

What happens:
1. The graph goes back to mid-2014.
2. An error appears, "No Data Available."

What should happen:
1. The graph goes back to early 2012.
2. The graph and table for the chosen release are shown.

This is because at some point in 2014, the data from 2012 and 2013 were archived to save disk space on the production database, and they have not yet been re-merged into the production database.

This makes it harder to see whether we are improving reliability of Ubuntu over time. We can see that, for example, 14.04 LTS is not as reliable as 12.04 LTS, but we can't compare interim releases like 12.10 vs. 14.10 or 13.04 vs. 15.04.

This is subject to an RT ticket somewhere, but I'm reporting it here so that it doesn't get forgotten.

According to a public post by Brian Murray, this should now have been fixed.

Unfortunately, when I follow the original steps to reproduce I still get the same result: “No Data Available.” for 12.10 or 13.04.

Keep in mind the default filter is for crashes in the past day. Given that 12.10 and 13.04 are End of Life we no longer accept crash reports from them so there are no crashes for the past day. Filter with a date range will work though e.g.:

https://errors.ubuntu.com/?release=Ubuntu%2012.10&from=2012/10/01&to=2012/12/30

The date filter, correctly, controls only the contents of the table and not the graph. But with no graph date range control designed or implemented, there is no way to prevent the graph from starting in April 2015 rather than the intended beginning of July 2012 or so, and that prevents it from showing what error rates were throughout Ubuntu 12.10’s or 13.04’s history. (When I first reported this bug I assumed that the graph was starting from the first remaining data; I don’t know why it’s starting from April 2015 now.)

When I follow your provided link <https://errors.ubuntu.com/?release=Ubuntu%2012.10&from=2012/10/01&to=2012/12/30>, it redirects to <https://errors.ubuntu.com/?release=Ubuntu%2012.10&period=day>, which still shows “No data to display”.

If I enter the date range 2012-10-01 to 2012-12-30 myself, the table eventually says “An error occurred while trying to load the most common problems” followed by a list of problems that were “First seen” in 12.04, 14.04, 15.04, or (in one case) “01.04”. The 14.04 and 15.04 entries suggest that the list is not of problems that occurred in 12.10.

I can quite believe that these are three or four separate bugs, and that there really are Ubuntu 12.10 and 13.04 errors recorded in the database. There just doesn’t seem to be any way to reveal them. :-)
