As mentioned in @seyn6gk's comment

Without changing anything, since teamviewer 13 a desktop environment/login with display manager like lightdm/sddm/gdm is required.

startx users can follow workaround mentioned in @r7v s comment

Workaround for startx

Create drop-in /etc/systemd/system/getty@tty1.service.d/getty@tty1.service-drop-in.conf with

[Service]
Environment=XDG_SESSION_TYPE=x11

The PKGBUILD should source from dl.teamviewer.com instead of dl.tvcdn.de since teamviewer.com is the canonical TeamViewer domain and would allow to directly verify the authenticity of the Debian packages.

If you want to update the package before it's updated in AUR, you can use this script:

#!/bin/bash

# Set this to updated version
# and run the script.
_newver=15.5.3

_oldver=$(grep "pkgver=" PKGBUILD | grep -o '[0-9.]*')

if [[ "$_oldver" == "$_newver" ]]; then 
    echo "Nothing to do."
    exit 0
fi

echo "Updating..."
sed -i "s|^pkgver=.*$|pkgver=${_newver}|" PKGBUILD
updpkgsums
makepkg --printsrcinfo > .SRCINFO

The package installation does say:

The Teamviewer daemon must be running for Teamviewer to work.
Execute 'sudo systemctl enable teamviewerd' in a terminal.

But nobody seems to read it. I suggested a fix for it earlier, among automatic update script and other improvements, here is the updated patch: https://pastebin.com/UgHp4u3S

Hi all, just a heads up. If you're having trouble with starting team viewer (connections unavailable), just start the daemon first

$ sudo systemctl start teamviewerd

Make sure to enable on start.

Hello to all follow xsession guys. I have the same problem using ly session manager and sway WM. Some additional details: logs are available in ~/.local/share/teamviewer15/logfiles/. Most relevant one is TeamViewer15_Logfile.log which contains a bunch of the following errors:

2020/04/26 21:36:28.840 52749 140543546674496 G!! SysSessionInfoManager::GetOwnProcessSession: No session found!, Errorcode=11

I thought it might be related to SESSION_MANAGER env variable and tried to run it from under xsm which does set that variable, but it did not change anything.

TeamViewer 12 works for me, but it does not support newer protocol version.

I'm a startx guy, not able to start the GUI either, no error message, same as txtsd.

It seems that DNSSEC checks fail for router*.teamviewer.com because of bogus CNAME. Disabling DNSSEC will resolve the network error.

$ drill -DT router9.teamviewer.com @1.1.1.1
...
[B] Unable to verify denial of existence for router9.teamviewer.com., because of BOGUS CNAME

Just want to share a weird issue (and solution) I had. If you've ever launched the GUI without starting the daemon first, you may want to remove /etc/teamviewer/global.conf before relaunching the GUI otherwise it won't allow you to type in email/password fields sometimes.

Why it is sourced to tvcdn.de and not directly to teamviewer.com if it is deb from Microsoft?
