New IDE update notice missing?

[NicoHood]

If a new library is available the IDE will prompt you for an update. But this does not seem to happen for the IDE itself, but I remember that this worked before.

Is it just because I recompiled the IDE myself, or does this only happen on linux?

And if it works again, how can I deactivate it? I've found this, but is this still the correct way to do so?

    # echo -e "\n# By default, don't notify the user of a new upstream version." \
    #         "\n# https://bugzilla.redhat.com/show_bug.cgi?id=773519" \
    #         "\nupdate.check=false" \
    #     >> build/shared/lib/preferences.txt

I believe the cause of the updatable IDE notification no longer being shown is that https://www.arduino.cc/latest.txt has not been updated since 1.6.1.

See: https://github.com/arduino/Arduino/blob/master/app/src/processing/app/UpdateCheck.java#L54

At last! latest.txt says 10801.

Yeah, we updated it last week 😄 Forgot to close this issue, thanks for the remainder

I do not get an update notification for archlinux. This is okay, as we dont want a notifications, however I am not sure if the feature is broken then?

[oqibidipo]

The problem is that the update URL in the IDE is an HTTP URL which is redirected to HTTPS. HttpURLConnection will not follow the redirect when the protocol changes. Changing the URL in the source will fix this for new new versions, but old versions will still remain silent about updates.

However, this could be solved by configuring the server to deliver latest.txt over HTTP while redirecting everything else.

[NicoHood]

Nah I think the webserver should stay with https. However it is good to know why this happens.

@oqibidipo @NicoHood thanks for the heads-up and the debugging session, we'll check what we can do to get the notification back on older IDEs (I think serving that file over http is ok)

It looks like https://www.arduino.cc/latest.txt has reverted to 10601 for some reason.

[facchinm]

@mastrolinux could you check please? Thanks @per1234

[per1234]

@mastrolinux https://www.arduino.cc/latest.txt is still at 10601. I just don't understand how this can be so difficult.

[mastrolinux]

I do not know what string I should write in the file, please advice @facchinm

[facchinm]

@mastrolinux 10807 will be fine ;)

[mastrolinux]

Done

I'm reopening because https://www.arduino.cc/latest.txt was never updated to 10808 when the release of Arduino IDE 1.8.8 happened.

Can this be automated or added to a official release checklist so that it doesn't get forgotten on future releases?

[facchinm]

@mastrolinux may you update that file to read 10808 ?

[alranel]

I'm running 1.8.8 (macOS) and I'm not getting the update notice.
http://www.arduino.cc/latest.txt currently contains 10809 and updates are enabled in Preferences. Not sure what's going on here...

[per1234]

I'm running 1.8.8 (macOS) and I'm not getting the update notice.

I also don't get update notices with Arduino IDE 1.8.8 running on a Linux 64 bit virtual machine or the Linux ARM 32 bit version on a Raspberry Pi.

I do get the expected update notice with Arduino IDE 1.8.8 on Windows 10.

[ngammarano]

https://www.arduino.cc/latest.txt currently says 10810.

Shouldn't it say 10812 as it is the latest version (https://www.arduino.cc/en/Main/Software)?

[oqibidipo]

1.8.13 has been out for two months, but latest.txt says 10812.

[rsora]

@oqibidipo https://www.arduino.cc/latest.txt should show 10813 now.

Happy coding!
