SRU bug-fix microrelease 2.0.8.1 in Trusty

I will not pretend that I understand how what the procedure look like for Trusty, but FWIW lyx 2.0.8 (the final 2.0.x version) should be released in the coming days, alongside 2.1.0 (which is less stable stuff of course).

Status changed to 'Confirmed' because the bug affects multiple users.

Jean-Marc, as an upstream developer, do you have any comments on this?

I definitely support this update request, although I am not really competent wrt Ubuntu policies.

LyX 2.0.8.1 is the final 2.0.x release, which is able to read files produced by the newer 2.1.x versions. In these stables series, we try very hard to avoid dangerous changes. Stables updates are supposed to be "no risk" releases, although of course life is never as simple as that! Since 2.0.8.1 is the last 2.0 version, we have been particularly careful. In particular, all 2.0.x version create the same lyx file format.

The only really new code is the one that reads 2.1.x files. This one probably still contains bugs, but IMO this release is better/safer than all previous 2.0.x releases.

Jean-Marc, could you attach, here as a patch, a debdiff of 2.0.8.1 for Trusty? You can find more details here https://wiki.ubuntu.com/StableReleaseUpdates#Procedure
I will do the paperwork.

This is the patch that goes from LyX 2.0.6 to 2.0.7. Note that 90% of the changes here are in the po files.

This is the patch that goes from LyX 2.0.7 to 2.0.8. 92% of the lines are related to po files.

[I mistakenly stated the same for the 2.0.7 patch, whereas it is actually 55% documentation, and less than 1% code.]

Finally, here is the (very short) pathch that goes from 2.0.8 to 2.0.8.1.

I have finally uploaded the three patches that are distributed with versions 2.0.7, 2.0.8 and 2.0.8.1
Note that these patches are not intended to be applied as such. They rather intended to be perused. We make no claim that they can be used to upgrade an existing source tree.

I would therefore propose to use directly lyx-2.0.8.1.tar.gz as full source tree.

I am not really aware of ubuntu way of handling this. Since trusty still ships LyX 2.0.6, the 3 patches are necessary to update LyX. The two big advantages I see are
- a very nasty data loss bug fixed in 2.0.7
- the ability to read LyX 2.1.x files (LyX 2.1.3 is shipped with vivid right now)

I suspect that the information I attached is not enough for the SRU process. Please ask me of any information that would be useful.

OK I made up a package and I've uploaded it. If accepted you'll get a message to test it with further instructions - please follow them.

Hello Amr, or anyone else affected,

Accepted lyx into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/lyx/2.0.8.1-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Jean, please also test the proposed package in trusty because you know better where things could go wrong. Thanks.

I will try to do so, but I only have access to one trusty installation (at home). I am not sure that I will be able to test soon.

I did a call for testers on the LyX mailing lists.

I tried it briefly and it works as far as I can see.

The only glitch is that the spellchecker does not work until it is configured as "enchant" in preferences.

I could be made the default by creating a file lyxrc.dist that contains only the line

\spellchecker enchant

It might be that this annoyance was already present in 2.0.6, actually.

I suspect that this will not be a regression for existing LyX users.

The spell checker is not a regression. It's already like that since 2.0.6.

This bug was fixed in the package lyx - 2.0.8.1-0ubuntu1

The verification of the Stable Release Update for lyx has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

Thanks Jean :)

Thanks Iain :)
