I found that gdm3 has vulnerabilities: https://lists.ubuntu.com/archives/ubuntu-security-announce/2018-August/004530.html

but I'm not able to update gdm3 to the version 3.28.2-0ubuntu1.4:

sudo apt-get --only-upgrade install gdm3
Reading package lists... Done
Building dependency tree       
Reading state information... Done
gdm3 is already the newest version (3.28.0-0ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I tried to remove gdm3 and fresh install but it still installs in version 3.28.0.

There is any way I can update gdm3 package? My Linux is Ubuntu 18.04.

Hi Mariusz! Welcome to AskUbuntu! Have you done an `sudo apt update` before you called `apt-get`? https://packages.ubuntu.com/bionic/gdm3 3.28.3 is in the security repository so it should update but you need to update the index with `sudo apt update` first.

Yes, I've already done `sudo apt update`. There was many hints and warning but I don't know what they mean. After all there were info `All packages are up to date.` so I guess everything is up to date. Maybe I'm missing some of the repositories?

If it's a fresh install, the security repos should already be enabled. Maybe check the contents of `/etc/apt/sources.list` and make sure there's `bionic-security` on the line of each repos. Something like this: `deb-src http://archive.ubuntu.com/pub/ubuntu/ubuntu/ bionic-security main ....`

Post the output of `sudo apt update`, please. Are you on a Raspberry Pi or something? https://packages.ubuntu.com/bionic/gdm3 says the newest version for ARM systems is indeed `3.28.0-0ubuntu1`

It is no clean install. I've added `deb-src http://archive.ubuntu.com/pub/ubuntu/ubuntu/ bionic-security main` because I did not found `bionic-security` repository but after `sudo apt-get update` I'm getting `Err:11 http://archive.ubuntu.com/pub/ubuntu/ubuntu bionic-security Release 404 Not Found [IP: 91.189.88.152 80]`

Edit your question and include the full output of `sudo apt update` if you are getting lots of warnings, you should not do anything else in `apt` until you sort out your problems with your package manager. Otherwise, you're likely to cause new problems.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
