Jerry:
This an appeal to those who would like to take part in a trial of Install Updates - the Yad version.

- Make a back up copy of /usr/scripts/updates-gui
- Copy the following contents into updates-gui

My thoughts:

- I think the progress windows look a lot nicer.
- Dialogues automatically adjust according to what text is inside aiding in readability.
- Yad allows for much more scripting options which translates to more features for our applications.

Trial will last as long as you are happy to run this version of Install Updates.

Looking forward to your feedback and opinion. :)

Artim:
Wonderful!  Thank you @misko_2083, @Jerry, @gerito1, and @ralphy!

trinidad:
Installed the YAD script and ran it this morning. Worked flawlessly. I would slow the blue sliding progress bar down a bit. It goes back and forth so fast on my machine that it's almost annoying, and given LL is aimed at Windows converts who are used to slower moving things involving such processes I think it moves a bit too fast. I do think it meets the criteria of some recent user requests here on forum involving updates. Looks good.

It fits to XFCE well. The best looking GUI for updates progress I've ever seen is the Debian 8/9 Gnome DE. It shows each package seperately and the progress of each each package during download and installation. As I said already this is well suited for an XFCE distro though, and Windows converts.

TC

Jerry:
Thank you TC, unfortunately there's no way to slow down the blue sliding progress bar. We could however look at changing it from pulsating to progress, but that's extremely tricky and hard to get right.

DenW:
Thank you Jerry and the other contributors to the Yad version of the Updater.

I am one of those LL users who have been experiencing the Blank update window using the Zenity version of Updater.  Yesterday all seemed OK but today I got another blank update window and cancelling and  trying a second time did not solve the blank window problem (even though I could open the updates.txt file in /tmp folder and see the updates available both times!).

So this evening I followed Jerry's instructions above and everything worked exactly as shown in the pictures above.  I would also make the same comment as Trinidad about the blue bar which seemed somewhat jerky on my older machine but still moved fast.  I wonder whether you even need the blue bar at all as the letters were always changing quickly during the whole process (except at the beginning of the download phase when there is usually a pause of 2-3 seconds and the blue bar was absent anyway).

Anyway I am going to keep the Yad Updater on my LL 3.6 until the next version of LL and will report back if any problem arises.

Thanks again.
