My system language is Chinese (traditional). Installing ttf-mscorefonts-installer doesn't help.
Workaround
According to https://github.com/AvaloniaUI/Avalonia/issues/4427#issuecomment-761074576, run muse-hub with LC_ALL=C, it works fine.
To Reproduce Steps to reproduce the behavior:
- Change system language to
zh_TW.UTF-8 - Run muse-hub
Expected behavior Muse-hub launch without error.
Platform information
- OS: fedora 6.0.9
- System language:
zh_TW.UTF-8, Chinese (traditional)
Additional context Install procedure (on fedora 6.0.9):
sudo ln -s /usr/lib64/liblttng-ust.so.1 /usr/lib64/liblttng-ust.so.0
sudo alien --to-rpm --scripts Muse_Hub.deb
sudo rpmrebuild -pe alien_output.rpm
# In editor:
# delete line Requires: liblttng-ust.so.0()(64bit)
# delete line %dir %attr(0755, root, root) "/usr/lib"
# delete line %dir %attr(0755, root, root) "/usr/bin"
# save and exit editor
sudo rpm -Uvh rpmrebuild_output.rpm
Thanks for the heads up! I'll look into patching this hopefully in the next release.
Thank you !But I meet a new problem now...I am using Ubuntu 2204,after I reinstall muse-hub,this workaround doens't work at all... I use Chinese (Simplified).The muse-hub version is 1.0.1.451.
Same thing for me here. Kubuntu 22.04, my system lang default is en_US, but I have also pt_BR , Muse hub doesn't work at all due to the same avalonia error. Tried a lot of things and none worked. Seems Muse-Hub was wrong package into .NET 6.
I lost track of this error, I'll take a look later today to see if I already patched this internally or not (otherwise I'll see how difficult it will be to fix).
I'm having the same error on Ubuntu 23.10 with an English language system:
