Couldn't run QGC


Under the Ground Control Stations, in topic “QGroundControl Installations”, when I run the executable ‘QGC.AppImage’, I’m getting a message about some missing versions(or files–screenshot shared). Before all this, while downloading QGC from the QGC website, I’d read from instructions given by them under Ubuntu Linux and executed the 3rd cmd–because 1st and 2nd was done in the start of the course). Now after installation, I’m not able to run QGC. Please correct me if I had done something wrong.

Cmds done(as shown in the QGC download and install page)

sudo usermod -a -G dialout $USER
sudo apt-get remove modemmanager -y
sudo apt install gstreamer1.0-plugins-bad gstreamer1.0-libav gstreamer1.0-gl -y

Thank you in advanced,


UPDATE: I was able to install GLIBCXX_3.4.26 from this website`GLIBC_2.29'+not+found
But I still have a problem with the installing the GLIBC_2.29 compiler


UPDATE 2: I got to the root cause of the problem and found out that Ubuntu uses only GLIBCXX 3.4.24 and GLIBC 2.27 as its compilation. However, the newest version of QGC is for Ubuntu 20.04 or above(I have installed 18.04). Hence you just have to download a less newer version(4.0.3 works for me).


Awesome, thanks for that! We are about due for a firmware/software version updating of the course, but in the meantime I will update the QGC recommendation for a 18.04 compatible version.
