Thank you!

Hello,

Can you send us the ulog logs? The procedure to get ulog logs is described here: Troubleshooting - 2.11

[JTplanner]

updated, like this?

[ocrave]

It seems that, for some reason, the path to /var/cache/firmwared/mount_points/ contains unexpected Chinese characters.

Can you restart firmwared with extra logs:

echo 'FIRMWARED_VERBOSE_HOOK_SCRIPTS = "y"' | sudo tee /etc/firmwared.conf

And show us the ulog logs?

[JTplanner]

Like this? Thank you!

Chinese characters. 無效的選項 = invalid option

Can you please reinstall realpath with:

sudo apt install --reinstall coreutils

Then try to start sphinx again.

If that still does not work, can you check if the realpath command is the one that comes with coreutils:

$ which realpath
/usr/bin/realpath

And its version number:

$ realpath --version

[JTplanner]

sudo apt install --reinstall coreutils

error occurred.
Is it a problem with coreutil?

[ocrave]

You may have installed a realpath package then enters in conflict with the one in the coreutils package. Can you get rid of it with:

sudo apt purge realpath

Then try to reinstall coreutils.

Great, it works,
thank you very much!
