fahcontrol won't launch - libffi update required

[NickNackGus]

Your Environment

• F@H Software version: foldingathome 7.6.21-1, fahcontrol 7.6.21-1
• Operating System: Linux Manjaro Cinnamon, kernel 5.15
• Browser: N/A, but Firefox 94.0.2
• libffi: 8

---

Expected Behavior

The Folding at Home Control application launches successfully.

---

Current Behavior

Folding at Home Control fails to launch with the following stderr when launched from a terminal:

Traceback (most recent call last):
  File "/usr/bin/FAHControl", line 25, in <module>
    from fah import FAHControl, load_fahcontrol_db
  File "/usr/lib/python2.7/site-packages/fah/__init__.py", line 25, in <module>
    import util
  File "/usr/lib/python2.7/site-packages/fah/util/__init__.py", line 26, in <module>
    import gtk
  File "/usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py", line 30, in <module>
    import gobject as _gobject
  File "/usr/lib/python2.7/site-packages/gobject/__init__.py", line 47, in <module>
    from gobject.constants import *
  File "/usr/lib/python2.7/site-packages/gobject/constants.py", line 24, in <module>
    import gobject._gobject
ImportError: libffi.so.7: cannot open shared object file: No such file or directory

The browser interface and telnet interface both continue to allow control of the Folding At Home client.

---

Possible Solution (Optional)

Update Folding at Home Control to libffi 8. As a workaround, it is possible to install the older libffi 7, but this is not preferred. It is also possible to control Folding at Home through the browser interface or telnet interface.

---

Steps To Reproduce

1. Install an OS with libffi 8 instead of libffi 7, such as Manjaro Linux Cinnamon.
2. Open a terminal and run fahcontrol
3. Note the error message about libffi.so.7

Context

I tend to leave FAH Control open in the background so I can monitor and reconfigure my FAH client. While I can still do this by other means, FAH Control is the easiest interface for me.
