Teamviewer stopped working for me

mcon

TeamViewer stopped working for me, presumably after some system upgrade; Im on a fairly up-to-date Debian GNU/Linux (Sid).

I am using it not very often, so I'm unsure exactly when and how things went wrong.

Today I tried to start the GUI and it silently failed; gui.log shows:

/opt/teamviewer/tv_bin/TeamViewer: /opt/teamviewer/tv_bin/RTlib/qt/lib/libQt5Core.so.5: version `Qt_5.12' not found (required by /usr/lib/x86_64-linux-gnu/libQt5WebKitWidgets.so.5)

Can someone suggest what to check?

UPDATE: it seems directory "/opt/teamviewer/tv_bin/RTlib" does not exist, neither on my machine nor in "teamviewer_14.6.2452_amd64.deb".

What am I missing?

 

Thanks in Advance

i just used apt to install the teamviewer  .deb file, and it automatically identifies the depending packages:

# apt install ./teamviewer_14.7.1965_amd64.deb

... libqt5core5a libqt5dbus5 libqt5gui5 libqt5network5 libqt5positioning5 libqt5printsupport5
    libqt5qml5 libqt5quick5 libqt5sensors5 libqt5svg5 libqt5webchannel5  libqt5webkit5 libqt5widgets5 libqt5x11extras5 ...

apt install whatever.deb

Will not work (unless "whatever" happens to be the NAME of a package). `apt` does *not* accept filenames.

Completely removing all TeamViewer leftovers and doing:

gdebi path/to/teamviewer/package/teamviewer_14.7.1965_amd64.deb
... or...
dpkg -i path/to/teamviewer/package/teamviewer_14.7.1965_amd64.deb
apt install -f

... will actually solve the problem.

I'm curious to know what distribution You are actually using.

On my Debian Sid `apt` does *not* behave that way.

mcon@cinderella:~$ ls -l Downloads/teamviewer_14.6.2452_amd64.deb 
-rw-r--r-- 1 mcon mcon 13966020 Oct 21 20:59 Downloads/teamviewer_14.6.2452_amd64.deb
mcon@cinderella:~$ sudo apt install Downloads/teamviewer_14.6.2452_amd64.deb

Installing using `dpkg -i` or `gdebi` works as expected though (but needs later fixing with `sudo apt install -f`).

i did the experiments using   Debian GNU/Linux 10 (buster)

I installed the VM using  debian-10.1.0-amd64-netinst.iso
