I am on Ubuntu 18.04.01 LTS on an old machine running Sandybridge i5 with 4 GB ram. After an update (and I havent run any updates for filezilla), the program has just stopped working.

I have followed all steps from this thread to try and revive, but nothing worked

unable to run filezilla

I did a full remove and purge of filezilla and after that installed the latest from the Ubuntu Software library (version 3.28), and started filezilla from the terminal. (Please see picture attached for the errors)

error on restarting filezilla

$ filezilla
filezilla: symbol lookup error: filezilla: undefined symbol: _ZN2fz6buffer3addEm

Any help and guidance will be appreciated. Thanks in advance.

  • Please try to start YOUR filezilla on YOUR Ubuntu and add its terminal output to the question. Linking to other questions is not useful. – N0rbert Sep 8 '18 at 8:19
  • Hi N0rbert - the second link has the picture of my terminal window, but pasting the error below for easy reference. PCSB16FG:~$ filezilla filezilla: symbol lookup error: filezilla: undefined symbol: _ZN2fz6buffer3addEm Thanks – Sameer Baya Sep 8 '18 at 8:38
  • Then please add output of which filezilla, ldd $(which filezilla) and apt-cache policy filezilla filezilla-common libfilezilla0 to the question. – N0rbert Sep 8 '18 at 9:15
  • Done Sir - added to the question – Sameer Baya Sep 8 '18 at 9:33

Your ldd output has one strange line:

$ ldd $(which filezilla)
...
libfilezilla.so.0 => /usr/local/lib/libfilezilla.so.0 (0x00007fc834bab000)
...

(it seems that you have installed filezilla from source before).

But correct line is:

libfilezilla.so.0 => /usr/lib/x86_64-linux-gnu/libfilezilla.so.0

So to fix the issue your should remove the problematic library manually:

sudo rm /usr/local/lib/libfilezilla.so.0*

and reinstall correct one from deb-package:

sudo apt-get install --reinstall libfilezilla0
