What app is this about, and its version: all
What YunoHost version are you running: 12.1.39
What type of hardware are you using: Old laptop or computer
Describe your issue
When installing applications on YunoHost systems configured with a Turkish locale (tr_TR.UTF-8), application installations consistently fail during configuration file templating.
This issue affects multiple applications (e.g. Roundcube, SOGo, others) and is not app‑specific.
When the system locale is set to tr_TR.UTF-8, YunoHost helper scripts fail to correctly initialize variables used in configuration templates (such as INSTALL_DIR, ADMIN).
As a result, application installation aborts even when all configuration options are left at their defaults.
Changing the system locale to en_US.UTF-8 resolves the issue immediately, and all applications install successfully without any other changes.
Environment:
YunoHost version: 12.1.x
Debian: Bookworm
Affected locale:
LANG=tr_TR.UTF-8
Share relevant logs or error messages
During application installation, the following errors are reported:
Variable $install_dir wasn’t initialized when trying to replace INSTALL_DIR
In the logs, the variable name appears incorrectly due to locale-specific character handling:
Variable $ınstall_dır wasn’t initialized
Example error output:
ERROR - roundcube indirilmedi:
Uygulama indirme script’inde (betikde) bir hata oluştu :
Variable $ınstall_dır wasn’t initialized when trying to replace INSTALL_DIR
in /etc/nginx/conf.d/.d/roundcube.conf
After changing the system locale using:
Shellsudo locale-gen en_US.UTF-8sudo localectl set-locale LANG=en_US.UTF-8sudo rebootDaha fazla satır göster
the errors no longer occur and all applications install correctly.
