Update: After extracting the files to any location (location does not matter, FileZilla can detect its own installation prefix), you can start the program using the filezilla executable in the bin/ subdirectory  (wiki.filezilla) Or compile FileZilla from source: Download and uncompress the downloaded file. tar -vxjf FileZilla_3.38.1_x86_64-linux-gnu.tar.bz2 Go to the newly extracted folder and install the missing libpng16 that FileZilla is requesting: Ubuntu 17.10 and older sudo apt install libpng16-dev Ubuntu 18.04 and newer sudo apt install libpng-dev Setup the ubuntu-toolchain-r PPA for installing the correct version of libstdc++.so.6 that FileZilla is looking for. sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt update sudo apt upgrade Copy over the updated FileZilla files to their correct locations: sudo cp -ravx * /usr/ Launch FileZilla as normal.…
