Various Muse-Hub issues on Linux; can't install Muse Sounds

• Dec 15, 2022 - 22:02

Hello -- Kubuntu 22.04 user here.

Muse Hub installs fine from the .deb. On first run, nothing happens (but I see in the task manager significant CPU usage from a Muse-related service.) On second run, the hub opens. (This pattern was the norm; however once it started up the first time.)

I changed the "Sounds install location" to a directory on another drive (NTFS). The download progresses fine, but installation apparently fails (there is not much notice given, just a dialog that says that the "Something went wrong", "ID: musesampler", "Type: Application") and there are no instruments visible in the mixer. I thought that dialog appeared just after downloading, but this last time it only appeared on the next run of muse-hub.

In the service_log.txt there are a variety of errors like this:
2022-12-15 13:07:12.2196|ERROR|Muse.Service.Interop.ServiceCore|Error when moving file /srv/muse-hub/downloads/Instruments: filesystem error: cannot rename: Invalid cross-device link [/srv/muse-hub/downloads/Instruments] [/my/alternative/path/to/muse-hub/Muse Hub Downloads/Instruments]

...not sure if that's relevant. Any idea how to get these sounds installed?

Some other issues and FRs:

• Muse Hub continually uses 100% CPU for a core (which comes to 12.5% total CPU usage on my system). Fans running, etc. Seems like something is busy for no reason. The process is Muse.Client.Lin
• FR: it would be great if MuseHub would check disk space before downloading -- I filled up / due to the downloads
• FR: the instruments should indicate their file size on the main page, not just in the detailed description; it's awesome but unusual (for a free scoring app) that these instruments would be so large, and the average user like me might assume that e.g. strings would be like a 50MB download :-) I had 3GB free on my root partition so I didn't even consider that these might fill that up
• once things are botched (e.g. when I filled my hard drive) clicking "clear Application cache" has no apparent effect no downloaded files (IIRC), i.e. disk space is still used.
• once a failure of some kind has happened, it's really unclear how to proceed. E.g. clearing the cache doesn't seem to change anything, and all the states of the instruments show that they've been downloaded but there's no clear way to "try again" with new settings, etc., no way to know what's happening in the background, what has been downloaded, what's corrupted, how to straighten it out, etc. [update: just found the alt-click hover-over tooltip; I appreciate the clean design, but a simple "uninstall" button might be more intuitive.]
• if I disable "Enable Community Acceleration" I still see ~300kb/s upload through my interface during download of the instruments; it seems like the preference is being ignored?
• FR: it would be great to have a separate way to download, install, and manage these instruments that didn't require an app.
• nit: the alternate "Sounds install location" dialog is unusably small when it first appears

For the record, in between attempts I've been doing "apt-get remove --purge muse-hub".

Please report Muse Hub issues on https://musehub.zendesk.com/

Note that MuseScore itself is currently unable to locate MuseSounds/Sampler if not installed in the default location (it seems that other locations on the internal drive do work, but not on external drives). You can however set up a symlink for that default location to wherever you want.
