Unsupported messages: MediaDice with emoticon field

[Nicholas Guriev]

[Impact]

Telegram Desktop 2.0.1 in Ubuntu 20.04 (Focal Fossa) does not support messages of new type, MediaDice with emoticon field set.

[Test Case]

Steps to reproduce:

 1. With latest Telegram Desktop (for example 2.1.5 available in Groovy Gorilla or from mobile client), type :dart: in any chat.
 2. Send that emoji 🎯.
 3. With Telegram Desktop of version 2.0.1, receive the MediaDice with dart as incoming message from yourself or from other person.

Expected behavior:

 1. You will see an animation with a dart and a dartboard.
 2. You will get a random number from 1 to 6.

Actual behavior:

 1. You see "This message is not supported by your version of Telegram. Please update to the lates version".

[Regression Potential]

Only one package is required to be updated. Any probable regressions will affect only one application. There is no other packages that depend on telegram-desktop.

I would say that is the expected behaviour of Telegram Desktop version 2.0.1.

I think the solution here would be backports:
https://wiki.ubuntu.com/UbuntuBackports
except that backports haven't been processed for a while, sadly.

[Nicholas Guriev (mymedia)]

I suggest to backport the telegram-desktop package of version 2.1.5+ds-1 as soon as it goes to devel release. Although, it is possible to pick necessary commits up to provide an isolated patch for the feature. But at this case, probability of errors increases, and such modifications will be less tested.

[Nicholas Guriev (mymedia)]

For convenience, here is a difference against 2.1.5+ds-1 from groovy-proposed.

[Nicholas Guriev (mymedia)]

It has been built.

[Nicholas Guriev (mymedia)]

Graham Inggs, I believe in our case SRU is reasonably. Ubuntu Wiki says that it is possible for "Updates that need to be applied to Ubuntu packages to adjust to changes in the environment, server
protocols, web services, and similar". And at some point current version in focal is not fully working.

https://wiki.ubuntu.com/StableReleaseUpdates

What else we can do to solve the issue? Who may do backport?

Hello Nicholas, or anyone else affected,

Accepted telegram-desktop into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/telegram-desktop/2.1.7+ds-2~ubuntu20.04.1 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 on 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, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Nicholas Guriev (mymedia)]

I confirm that now MediaDice with emoji is displayed. I have tested 2.1.7+ds-2~ubuntu20.04.1 version in a virtual machine in Ubuntu 20.04 with GNOME and in KUbuntu 20.04 (both loaded from Live .iso image). I have also tested that upgrading from 2.0.1+ds-1build1 version is possible seamlessly.
