deepin流云 - Huge thanks! I'll try this out. But...
"sumary.sig" - what's a file is that essentially?! Could you please explain. 🙂 And why my system "Deepin 25.0.10" couldn't find it, and upgrade through the convenient command *sudo deepin-immutable-ctl upgrade?
Thank you for your time!

I'd like to know what "summary.sig" is. What issue did you encounter during the update? Please provide a screenshot so I can better assist you. Also, the command sudo deepin-immutable-ctl upgrade has been deprecated. To update the system, we still recommend using the command I provided earlier.

First of all, I appreciate your help, I really do.
Regrettably the command "sudo apt update && sudo apt dist-upgrade" doesn't work for me. 🙂 When I use "sudo apt update", I just get a bunch of connection errors (as seen on the screenshot below).
And using "sudo apt dist-upgrade" aftewards brings no changes at all. :) It says "0 packages to upgrade..." and so on. The system won't even try to upgrade.
By the way, my internet connnection is OK. However there is not any sub-folder named "Driver-25" in the folder "https://community-packages.deepin.com".

Well, actually the IP you blurred out is the IP address of our update server. That IP is what can help us locate the problem, since you're currently unable to connect to the update server. We need to see where that IP is connecting to.

Oh I'm so sorry, shouldn't blur the IP. 🙁 A stupid thing it was, and I did it spontaneously, without rhyme or reason. There below is the full screenshot:

Hello my friends! First of all, thank you for amazing work on "Deepin-desktop-community-25.0.10". I'm using this system, and it's just so cool, but I cannot upgrade it in any way.
I've tried the following command in terminal:
sudo deepin-immutable-ctl upgradeAnd I got the following message:
Fetching summary from remote default Failed to fetch summary: while fetching https://community-packages.deepin.com/deepin/immutable-repos/summary.sig: [28] Timeout was reachedI've looked up this address on the internet and there wasn't any file named "summary.sig". So it's a bit confusing to me.
I cannot use "AppCenter" or "System Settings"'s sub-menu as an alternative way of upgrading. Neither of them is working alas. It's never worked actually, since my first days of using "Deepin25". "AppCenter" doesn't even open.
So I need your help desperately. Thanks anyway. :)
