Hi Billy, thanks a lot for the response! It seems that creating the British locale indeed solved my problem. I am using the US utf8 locale as default, but the British one was not available. In case anyone else uses Debian: On Debian, locales are handled differently from Ubuntu: The command 'locale-gen' does not take any command line options, but generates all locales as listed in the file /etc/locale.gen Hence, I had to uncomment the line containing 'en_GB.UTF-8 UTF-8' and run locale-gen (as root or via sudo).

Hi Tim,

Can you try installing the en_GB.utf8 locale? For unicode support, the default locale is set to en_US.utf8 unless you define the LC_ALL to be some other locale with UTF8 support.

On Debian/Ubuntu distributions that locale seems to only work if en_GB.utf8 is also available.

You can check what locales are available by typing

locale -a

If en_US.utf-8 and en_GB.utf-8 are not available, you can install the locales with the instructions here

https://wiki.debian.org/Locale https://help.ubuntu.com/community/Locale#A.28Re-.29Generating_locales

Basically, if those two locales are not available, you can run

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

The last line may not be needed.

Let me know if it's still not working.

Dear all,

I installed phenix 1.19.2.4158 on Debian testing (version 11.0) and Debian stable (version 10.10).

On Debian stable, phenix works just fine. On Debian stable (kernel 5.10.0-7-amd64), when I type 'phenix' at the command prompt, I get the usually error about the locale 'en_GB' not being available, and the Phenix splash screen, that disappears automatically. After that, nothing happens. The prompt does not return, phenix is running tg@fibonacci:~$ ps -eLF | grep phenix tg 3823 3776 3823 0 1 33859 83056 6 09:36 pts/1 00:00:00 /xtal/Suites/Phenix/phenix-1.19.2-4158/build/../conda_base/bin/python2.7 -Qnew

/xtal/Suites/Phenix/phenix-1.19.2-4158/build/../modules/phenix/wxGUI2/command_line/main.py

but no GUI shows up.

I can use phenix through ssh on stable, so that this is not an urgent issue. I was just wondering if anyone might have a clue why phenix GUI won't show up on Debian testing? I tried two window managers, KDE and awesomewm on two different computers.

Best wishes, Tim
