I've seen this before on Ubuntu; infuriatingly it happened on some machines and not others, presumably because they had different libraries installed

It's caused by an accent in the citations for Phenix on the splash screen that pops up not being interpreted properly.

For most of my machines, setting the locale worked.  In the end I got frustrated and edited the accented characters out of the citation in the source code (modules/cctbx_project/libtbx/citations.params).  My apologies to G Bunkóczi, who is now lacking an accent in his name on my machines.  The commands to set/update the locale are:

sudo locale-gen en_US.utf8
sudo locale-gen en_GB.ut8
sudo update-locale

If you don't want your machine to be US/GB English substituting other locales might work but I haven't tested it.

Having said all that, the Phenix developers probably have a much more elegant solution.

Regards,

Chris

Dears,
I am using Ubuntu 24.04 and have successfully installed phenix-1.21.2-5419. However, when I attempt to launch the GUI by running the phenix command, it fails with the following error:
Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/local/phenix-1.21.2-5419/modules/phenix/wxGUI2/App.py", line 961, in _excepthook

    if (app.bug_timer.IsRunning() is False):
AttributeError: 'PhenixApp' object has no attribute 'bug_timer'

Original exception was:

Could you kindly advise on how to resolve this issue? I would greatly appreciate your assistance.
Looking forward to your reply.
Best regards
