I'd like to copy a firmware update file to my Canon 7D camera.

After it was auto-mounted by thunar + thunar-volman + gvfs-gphoto2 I tried the following:

$ cp eos7d-v205-win/7D000205.FIR /run/user/1000/gvfs/gphoto2\:host\=%5Busb%3A001%2C012%5D/
$ echo $?
$ ls /run/user/1000/gvfs/gphoto2\:host\=%5Busb%3A001%2C012%5D/

So that went into a black hole.

The first time I try to copy it with Ctrl-c and Ctrl-v prints the following error message when pasting the file:

Error writing file.

-108: No such file or directory.

Do you want to skip it?

If I try again after that it simply crashes:

$ thunar
Segmentation fault (core dumped)
$ echo $?

The Gphoto 2 shell has an undocumented put function which I also tried:

$ sudo umount /run/user/1000/gvfs
$ gphoto2 --shell
gphoto2: {.../eos7d-v205-win} /> help put
Help on "put":

Usage: put [directory/]filename
        Upload a file

* Arguments in brackets [] are optional

So this function takes a single argument with an optional directory. Weird, but should be doable. Some attempts at making it work:

$ gphoto2 --shell
gphoto2: {.../eos7d-v205-win} /> ls
gphoto2: {.../eos7d-v205-win} /> put 7D000205.FIR                       

*** Error ***              
You need to specify a folder starting with /store_xxxxxxxxx/
*** Error (-1: 'Unspecified error') ***
gphoto2: {.../eos7d-v205-win} /> put /store_00010001/7D000205.FIR

*** Error ***              
PTP Access Denied
*** Error (-1: 'Unspecified error') ***
gphoto2: {.../eos7d-v205-win} /> put /store_00010001/MISC/7D000205.FIR

*** Error ***              
PTP Access Denied
*** Error (-1: 'Unspecified error') ***

Maybe it's not supported?

Digikam has an upload feature, but that just reported 'Failed to upload file "7D000205.FIR".' Running it from the shell produced no more information.

Too many WTFs per minute. What do I need to do to copy a file to my camera in Arch Linux?

You can use gvfs-copy command. The syntax is:

gvfs-copy source-URI destination-URI

So this should work:

gvfs-copy file:///home/user/eos7d-v205-win/7D000205.FIR file:///run/user/1000/gvfs/gphoto2\:host\=%5Busb%3A001%2C012%5D/
