This might have something to do with TeamViewer, because i have it installed and have found it mentioned on the internet with it.

But still, http://LnxRelease-02/deb doesn't look like a real web domain - so what's going on here?

EDIT: I'm using Ubuntu desktop 20.04 focal fossa

EDIT 2: Here is an image of the issue: Screenshot of LnxRelease inside Software updates

  • This is something wierd and maybe unsafe. It is not related to teamviewr. It is something else.

  • This looks like malware to me. I suggest to remove it and re-install the system.

  • Well i don't remember installing any unknown softwares, except Signal messenger recently. It used this command, which felt safe for me because i manually downloaded and inspected the .asc file, it was only a private key. curl -s https://updates.signal.org/desktop/apt/keys.asc | sudo apt-key add - echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" | sudo tee -a /etc/apt/sources.list.d/signal-xenial.list sudo apt update && sudo apt install signal-desktop

This is from TeamViewer. Whomever built the .deb and .rpm packages incorrectly included their internal repository address, instead of the public external repository.

apt, zypper, yum, & etc. will fail as this is not resolvable outside of the TeamViewer internal network. At least for OpenSuSE, this repo is listed as 'tvinternal.repo'.

I went to the TeamViewer website and just downloaded the latest .rpm package, then uninstalled the old one, and installed the newly downloaded rpm package.

{21}# rpm -e `rpm -qa | grep teamviewer`
Removed /etc/systemd/system/multi-user.target.wants/teamviewerd.service.
Clearing assignments ...
warning: /etc/zypp/repos.d/tvinternal.repo saved as /etc/zypp/repos.d/tvinternal.repo.rpmsave

{22}# rm /etc/zypp/repos.d/tvinternal.repo.rpmsave

{23}# zypper -v in ./teamviewer-suse_15.5.3.x86_64.rpm

{24}# ls /etc/zypp/repos.d/t*.repo

Now updates work as expected.


  • I contacted their support long ago, there was no reply, so accepting this as an answer.
