Red triangle with an exclamation mark Ubuntu 16.04

Question

so I'm running Ubuntu 16.04 and the red exclamation mark just appeared. What can I do??

but everything is up to date on the computer

here's what I get, when I use the update/upgrade command:

Ign:1 http://dl.google.com/linux/chrome/deb stable InRelease Ign:2 http://dl.google.com/linux/talkplugin/deb stable InRelease Hit:3 http://dl.google.com/linux/chrome/deb stable Release Hit:4 http://am.archive.ubuntu.com/ubuntu xenial InRelease Get:5 http://dl.google.com/linux/talkplugin/deb stable Release [1,347 B] Get:6 http://am.archive.ubuntu.com/ubuntu xenial-updates InRelease [93.3 kB] Get:7 http://dl.google.com/linux/talkplugin/deb stable Release.gpg [198 B] Get:8 http://security.ubuntu.com/ubuntu xenial-security InRelease [92.2 kB] Hit:10 http://ppa.launchpad.net/webupd8team/y-ppa-manager/ubuntu xenial InRelease Hit:11 http://am.archive.ubuntu.com/ubuntu xenial-backports InRelease Fetched 187 kB in 1s (169 kB/s) Reading package lists...

In the launcher bar on the left have you got the new 'Ubuntu Software' item ? (Not to be confused with old 'Ubuntu Software Centre', which if you upgraded to get 16.04, came from an older Ubuntu version and has the same design of icon) If you have the new 'Ubuntu Software', click it and select the 'Updates' tab, click it and see what's available. — NickT, May 01 '16 at 13:41
You have installed chrome in some strange way, without the required security keys. I would advise to uninstall chrome and the installing it again (the same for this "talkplugin" that I do not know). — Rmano, May 02 '16 at 14:49
Does this answer your question? How to fix apt: Signature by key uses weak digest algorithm (SHA1)? — karel, Apr 02 '22 at 06:02

It could be an error relative to some broken updates.

You can try to fix this error updating package list:

sudo apt-get update
sudo apt-get upgrade

Note: before run the above commands check that your computer is connected to internet.

I hope this could help you.

it says: E: Failed to fetch http://dl.google.com/linux/talkplugin/deb/dists/stable/Releas

@Tatev Kot Vardapetyan Are you on 32 bit or 64 bit PC? – Danibix May 01 '16 at 13:33
it is 64 bt os type – Tatev Kot Vardapetyan May 01 '16 at 13:40
@TatevKotVardapetyan You have a broken repository (or you didn't report the error correctly). please add to your question the full output of sudo apt-get update – Rmano May 01 '16 at 14:39
@TatevKotVardapetyan If the error is exactly as you pasted it here, you're missing an "e" at the end of "Releas". You will need to edit that section of your /etc/apt/sources.list either by hand or through the "software sources" options screen to add the missing letter. Then you can run "sudo apt update" again. – May 01 '16 at 20:08
@Rmano done as you said.. – Tatev Kot Vardapetyan May 02 '16 at 13:39
@NickWeinberg , no, the ''e'' is not missing, it was my mistake when pasting – Tatev Kot Vardapetyan May 02 '16 at 13:40
