[gentoo-user] Advice needed regarding udisks

[gentoo-user] Advice needed regarding udisks

[Grant]

I'm having a problem detaching a USB camera from a desktop.  I found a
Ubuntu bug for the problem which states that it is a bug in udisks-1
which won't be fixed upstream and the solution is to upgrade to Ubuntu
12.10 which uses udisks-2.  Can anyone recommend a good course of
action for me here?

Here is the problem:

# udisks --detach /dev/sdb
Detach failed: Error detaching: helper exited with exit code 1:
Detaching device /dev/sdb
USB device: /sys/devices/pci0000:00/0000:00:02.0/usb2/2-6)
SYNCHRONIZE CACHE: FAILED: No such file or directory
(Continuing despite SYNCHRONIZE CACHE failure.)
STOP UNIT: FAILED: No such file or directory

Here is a pretend emerge of udisks:

# emerge -pv udisks
[ebuild  N     ] sys-apps/gptfdisk-0.8.6  USE="icu ncurses -static" 0 kB
[ebuild  NS    ] sys-fs/udisks-2.1.0:2 [1.0.4-r5:0] USE="gptfdisk
introspection -cryptsetup -debug (-selinux) -systemd" 0 kB

Here is the Ubuntu bug describing the problem (comments 81, 82, 85):

This is actually a portage question.  How can I install udisks-2 in a
way that will fix this problem?  I'm confused by how to handle the
slotting behavior.

emerge udisks:2


A SLOT is treated as two different packages that just happen to have the
same name, so there's a ":<something>" appended to differentiate them.

Other packages that use udisks will define which SLOT they DEPEND on in
their ebuild, if it's important to distinguish them that way.

It looks like installing udisks-2 to SLOT 2 would mean installing into
a new slot.  I don't think that will fix the behavior I described
below.  I think I need to upgrade one of the currently installed
udisks slots to udisks-2.  Is that correct, or am I misunderstanding
and I should just follow your instructions?

I think the issue here is that we are not understanding what the
problem is. It happens with an application in particular, or with a
desktop environment? It happens when you try to umount the device, or
when you disconnect it from the computer? Do you loose data in the
camera, or when transferring photos to your computer? Or is only that
you don't like the error reported?

udisks is deprecated and (AFAIK) unmaintained. Do you *really* need
it? Or perhaps is being pulled by a package that actually supports
udisks2, but you have a USE flag that pulls udisks1?

In GNOME, if you have gvfs with the gdu USE flag, it pulls libgdu,
which pulls udisks1. But you don't actually need it; everything is
covered by the udisks USE flag (which pulls udisks2).

Do a "equery depends udisks" and see what is pulling udisks1.

When trying to eject a USB camera in thunar in xfce4, the error
appears and the device does not umount.  Here is a command that also
produces the error:

# udisks --detach /dev/sdb
Detach failed: Error detaching: helper exited with exit code 1:
Detaching device /dev/sdb

I get the following:

# equery depends udisks
 * These packages depend on udisks:
gnome-base/gvfs-1.12.3-r1 (udisks ? >=sys-fs/udisks-1.90:2)
gnome-base/libgdu-3.0.2 (=sys-fs/udisks-1.0*:0)

Why is the udisks USE flag masked for gvfs? Try to emerge -C
sys-fs/udisks:0, and reemerge gvfs with USE="-gdu udisks". If you get
to emerge gvfs with the udisks USE flag and without the gdu one, I
believe your problem will go away.

                        ^^^^^^^

There's your problem.

thunar depends on gvfs, which can use udisks, but in your case the USE
flag is forced, masked, or removed.

You need to find out why that happened, it might be a profile thing,
maybe it's a local config. Try

grep -r udisks /etc/portage/

Nothing comes back from that grep.  My profile is
default/linux/amd64/13.0/desktop.  What else could be preventing me
from enabling that USE flag?

It might be masked by the profile. As I understand it, recent EAPIs
allow USE flags to be forced per-profile. This makes sense - a dev might
enable USE=udev everywhere except on gentoo-freebsd profiles, just as an
example. But I'm not yet up to speed on how to detect and over-ride such
things.

I think you should log a bug now at b.g.o. and let the devs tell you
what's really going on with your selections.

Will do, and I'll report back with the results.

OK, there it is.  If I keyword gvfs I get into trouble because
gobject-introspection wants <dev-libs/glib-2.33 and gvfs wants
>=dev-libs/glib-2.36.

Don't keyword gvfs,

for gvfs:

USE="-udisks gdu"

gvfs doesn't care what does the automounting, as long as something does

That's what I have now and I have this ejecting problem.  Should I
just emerge udisks-2 into a new slot?

I have a hunch that won't work and USE="udisks" is hard masked for gvfs.
Logic tells me that even if udisks:2 is available, gvfs won't use it.

But, it's worth a try.

I also think you need the maintainer to take a closer look - it all
looks like the ebuild needs some tweaking, or maybe it's just a magic
combination of USE that we missed.

I tried but no luck.  I should hear from the maintainer soon.

Another SLOT question.  udisks:0 was installed and now udisks:2.  What
about slot #1?

There is no SLOT 1 for udisks.

SLOTs have arbitrary names that can be anything, they are not named
numerically in sequence. The maintainers usually name a SLOT after the
major version number becuase that is very descriptive, but it's not required

There is only one SLOT name that has magic significance, SLOT:0, which
is the default if the package is not explicitly in a slot.

It's going to snowball from there. You could try to keyword
gobject-introspection, but it will probably need for you to keyword
more packages, which in turn will require even more keyworded
packages. It can be done automatically with the --autounmask emerge
option, but if you are mixing stable and unstable packages, you need
to know what you are doing.

GNOME 3.8 is going stable soon (or so I keep hearing); when that
happens, the parts of the stack that you need for the new gvfs will be
stable. You could wait for it to happen.

No help from B.G.O. yet and I'm wondering if I should update libgdu to
see if that fixes it.  Is libgdu the same thing as gnome-disk-utility?
 If so, the latest version is 3.9.0 compared to 3.0.2 in portage:

https://git.gnome.org/browse/gnome-disk-utility/

Alternatively, should I try hacking the ebuild to unmask the udisks USE flag?

Just saying you should be using `udisksctl` command instead of the now 
obsolete `udisks` command

udisksctl command = new udisks 2
udisks command = old udisks 1

OK, but first I need to figure out how to get gvfs to use udisks instead of gdu.

by emerging gnome-base/gvfs from ~arch with USE="udev udisks"

the stable gnome-base/gvfs is not compatible with UDisks 2.1

but by upgrading gnome-base/gvfs on stable to ~arch version with 
USE="udev udisks" is then again not compatible all the way with GNOME 
2.x, so that's why it's still in ~arch

If I keyword gvfs I get into trouble because gobject-introspection
wants <dev-libs/glib-2.33 and gvfs wants >=dev-libs/glib-2.36.

So?

Obviously I meant to say 'keyword gvfs *and it's dependencies* from 
~arch if you want to use USE="udev udisks"'

So that means bunch gobject-introspection, gobject-introspection-common, 
glib, and likely some others too, Portage will them you about them

The above glib dependencies are circular.  There is no way to satisfy them both.

Samuli means this:

$ grep dev-libs/glib /usr/portage/dev-libs/gobject-introspection/*.ebuild 
/usr/portage/dev-libs/gobject-introspection/gobject-introspection-1.32.1.ebuild:	>=dev-libs/glib-2.31.22:2
/usr/portage/dev-libs/gobject-introspection/gobject-introspection-1.32.1.ebuild:	<dev-libs/glib-2.33:2
/usr/portage/dev-libs/gobject-introspection/gobject-introspection-1.34.2-r1.ebuild:	>=dev-libs/glib-2.34.1:2
/usr/portage/dev-libs/gobject-introspection/gobject-introspection-1.36.0.ebuild:	>=dev-libs/glib-2.36:2

So you need >=gobject-introspection-1.34.2 to satisfy the dependencies.

OK, I was able to do this and ultimately emerge udisks-2 with
USE="-gdu udisks" if I un-emerged gobject-introspection first.  I
won't know if this fixed my original problem for a few days but I will
report back.  Thank you everyone for sticking with me on this.

You can't upgrade a slot, portage sees as if they were two different
packages. You can't "upgrade firefox to chrome" either for the same
reason. Instead, you unmerge the slot you do not want and fix everything
that remains (@preserved-rebuild, revdep-rebuild etc)

You haven't yet said which app you are using that won't umount the
camera, so it's a bit difficult to give proper advice. We'd need some
info first?

- what is the app in question?
- relevant USE flags it uses?
- what does it link to?
- does that pp support udisks:2?
