To Reproduce
Copy and paste the commands (and their output) to execute in order to reproduce

$ trash-empty

Expected behavior
Run command and empty trays directory

Volumes detail
Seems trash-list --debug-volumes too has the same error

This seem be caused by this issue of psutil giampaolo/psutil#2191

I need help for this problem from someone that has access to an Termux PRoot Ubuntu installation and knows how it work.

A possible workaround is to add a flag in trash-empty to disable the search of partitions:

$ trash-empty --current-volume-only

@mizzunet Thank you for your detailed submission!
@mizzunet can you please send me the output of the command "df" on your Termux system?

[mizzunet]

$ trash-empty --current-volume-only

I'm afraid this one doesn't work either

...
 trash-empty: error: unrecognized arguments: --current-volume-only

So is trash-list

"df" on your Termux system?

@mizzunet
The workaround I mentioned earlier is something I think we need to have in trash-cli to workaround the problem in psutils under Termux. Sorry if weren't clear.

The option --current-volume-only yet is not available in your trash-cli installation because I started working on after I sent my last message.

I have finished it yet but during the working I discovered a possible temporary solution for you.

Try to prepend this the setting of the variable TRASH_VOLUMES before launching the trash-empty command.

$ TRASH_VOLUMES=$PWD trash-empty

It should at least empty the trash directory in the current volume.
The TRASH_VOLUMES variable works with trash-empy, trash-rm, and trash-list.

Please let me know if it works and also please send me the output of the following command on Termux

$ uname -a

So I can add a warning in trash-cli when it detects that is running under Termux if problems arises when searching for volumes.

[mizzunet]

Please let me know if it works

It does. Thanks :)
