Bug 172023

It's not a bug with KDE4. Partitions in /etc/fstab can ONLY be mounted by the root user.

An optimum solution would be to ask the user for the root password so it can mount it; sorta like Kubuntu 8.10 does, but only make it part of KDE 4.

And why it works with KDE 3.5? 
And why it works as user in konsole?

man mount
man fstab

that error comes from mount, not KDE.

what user do you run your virtual machines sessions as? can you mount them from konsole inside the VMs?

I have this fstab entry since 5 years and it works in console and in kde < 4.0 but not in >= 4.0.

Here Screenshot from Kubuntu 8.04 (LiveCD Mode + 1 HDD) in Virtualbox.

And you can see... it works!

it's not a mount problem!

Works in console but not with KDE 4

If I remember well HAL has got its own set of permissions. Anyway it may be an HAL issue or it may be a Solid bug.

Hi I'm having the same problem, searching for solutions. In KDE 3.5 it worked fine.

Using /mnt/backup instead /dev/sda0 as device in plasma-icon could be a workaround for you on mounting BUT! Neither it works for unmounting nor opening folders in dolphin.

Is it really posible that no kde-dev can fix the problem in 4 month and no kde-dev knows kde 3.5 (it works on kde 3.5!!!) or can test it? -.-'

Same error since 4.0 to 4.2.0.

Find a KDE/Plasma bug for dummies:

KDE 3.5 Vid: http://www.2blabla.ch/stuff/Bugreports/KDE4-Bugs/kde3.5.avi (34MB - XVid4)
KDE 4 Vid: http://www.2blabla.ch/stuff/Bugreports/KDE4-Bugs/kde4.avi (36MB - XVid4)


i hope the kde devs see and understand the problem now. 

This one clearly goes through the old KDesktopFileActions facilities in kio. No idea if there's plan there to support solid. Reassign there.

Why would mount() in kio_file need to support solid? We just call `mount` there, (or pmount) like we did in 3.5. I don't remember changes in that code....

F. Di Milia: no need to call us dummies, and 4 months is nothing compared to some other open bugs. There are thousands of open bug reports, we're overloaded.

I need to see the contents of the desktop file, and the output from kio_file to find out more about the problem. You can find it in ~/.xsession-errors, most probably. Debug area 7101 (check with kdebugdialog that it's enabled), and a debug build is needed (otherwise debug output is turned off).

Right, I made no sense there. What's sure though is that this feature doesn't go through solid at all.

File created with "Link to dev"

[Desktop Entry]
Dev=/dev/sdd1
Icon=drive-harddisk
MountPoint=/mnt/backup
ReadOnly=false
Type=FSDevice
UnmountIcon=hdd_unmount


I've nothing in .xsession-error if i try to mount the HDD with link to dev.

I'll compile my Gentoo now with debug useflag on.


Btw. Sorry for the dummies but i was soooooo nerved.

Hm.

I compiled gentoo with debug useflag and i can see some output in .xsession-erro but nothing like 7107 kio_file and 7101 (kio_file) is turned on in kdebug.

Example:

angelus ~ $  cat .xsession-errors | tail -n 5
kded(3246)/khotkeys KHotKeys::ActionData::update_triggers: ### Update triggers:  "Vorheriges Unterfenster aktivieren" : false
knotify(3284) KNotify::event: 1297  ref= 0
yakuake(3341)/kdeui (KNotification) KNotification::slotReceivedId: 0
yakuake(3341)/kdeui (KNotification) KNotification::close: 0
yakuake(3341)/kdeui (KNotification) KNotification::~KNotification: -2
angelus ~ $

do i something wrong?


Btw. The contextmenu of root has a "u/mount" option for "link to device" but there is no "u/mount" option in the contextmenu of a normal user like in KDE 3. 


I found out:

Orginal created from Link to Device (u/mount doesn't work as user):

[Desktop Entry]
Dev=/dev/sdd1
Icon=drive-harddisk

Edited by me (only mount does work as user (double click on icon to mount)):

UnmountIcon=hdd_unmount

Hi David. 

Your tip with 'pmount' was a good hint.
pmount wasn't installed at all in my intrepid based kubuntu.

After installing pmount, i could mount my nfs device with the kde-link and it was opened automatically in Dolphin. Before I installed pmount, I had the same problems like F. Di Milla.

Right now I'm just missing the "u/mount" option in contextmenu of that icon.

angelus ~ $  pacman -Qs pmount
local/pmount 0.9.18-2
    mount removable devices as normal user
angelus ~ $


I've installed pmount but still not works.

KDE 3.5 = works
KDE 4 = not works

And i can't believe that all Distrobtion forgot to install pmount but kde 3 works.

I'm using it for a nfs-mount.

The bug is still in  KDE 4.3 RC3.

Testet with Kubuntu 9.10 Alpha 3.

Can pls someone fix it?

This bug is still reproducible in current trunk too.

I can confirm. Still in 4.3.1 - Gentoo.
Could someone fix it?

Link 2 Device works with KDE 4.3.2 for me. :)

Can someone comfirm it?

"Link to Device" works with KDE 4.3.2 for me. :)

Can someone comfirm it?

No, still without luck on 4.3.2 Gentoo. Still getting "Only root can do this" error. I have same issue also with NFS volume. Am I missing something in fstab or groups?

Sorry for badly posted reference to bug 203074

I can confirm, that this bug disapper when the MountPoint option in desktop file is leaved empty. When MountPoint is set than error ocurred.

Fstab

link to device works for me with...

Sama Shares (mount.cifs)
Linux Partitions (mount)
Windows Partitions (mount.ntfs-3g)

I can't test NFS. :(

Works NFS as user in the console?

Have you tried to setuid for mount.nfs and are the permissions for you mount-point right?

I ask because i needed setuid for mount.cifs.


Here my fstab

I forgot...

Here my link to device files.

Yes, mount as user in console works prefectly for win/linux partitions also for NFS volumes. Today I managed link to work properly with MountPoint left empty.

*** Bug 203074 has been marked as a duplicate of this bug. ***

Bug remains in KDE 4.3.3

This bug getting worse in KDE 4.3.4. The workaround, when MountPoint variable in the desktop file is left empty, stopped to work. Now following error appears: Could not mount device. The reported error was: mount.nfs: an incorrect mount option was specified.

I ask developers, please, do something with this annoying bug.

I think I found the bug, perhaps? Sorry but I have no time to try for myself...
Looking at the source code (I'm on Gentoo, KDE 4.3.3, don't know how is mapped on official repository) the file kioslave/file/file.cpp inside the archive kdelibs-4.3.3.tar.bz2):
- at line 972 there is a for statement to make 2 iteration and call "mount" with different parameters; but the variabile containing the string with the command line is initialized at line 969 (before the for cycle) and never resetted.

In the log file attached kdebug.dbg I saw this lines that seems to confirm my idea:
kio_file(4000) FileProtocol::mount: FileProtocol::mount _fstype=
>>> First try
kio_file(4000) FileProtocol::mount: "/bin/mount  /dev/sdd1 /mnt/backup 2>/tmp/kde-angelus/kio_fileSL4000.tmp" 
kio_file(4000) FileProtocol::mount: "mount: Nur „root“ kann dies tun
" 
kio_file(4000) FileProtocol::mount: Mounting with those options didn't work, trying with only mountpoint 
>>>Second try
kio_file(4000) FileProtocol::mount: "/bin/mount  /dev/sdd1 /mnt/backup 2>/tmp/kde-angelus/kio_fileSL4000.tmp  /mnt/backup 2>/tmp/kde-angelus/kio_fileSL4000.tmp" 

The second iteration should be "/bin/mount mnt/backup 2>/tmp/kde-angelus/kio_fileSL4000.tmp" (only the mount point, no device) instead is the first try with appended the parameters of the second.

I will attach a patch for you to review.

Regards,
Stefano

Command line for mount invocation

Move the declaration/intialization of the string with the mount command line inside the 'for' statement.

Still remains in KDE 4.4. No solution yet.

Hi all,
I'm a kubuntu user 9.10 with kde 4.4. I have the same problem.

I can confirm that the patch I attached some time ago is fixing this bug, at least in my case, an nfs share declared in /etc/fstab:
netsrv:/mnt/archivio /mnt/archivio nfs noauto,user,users,tcp,noatime 0 0

I tried it on Gentoo with kde 4.3.3 and 4.3.5.

But it is not included in the mainline.

Still not workeee in 4.4.1 :(

Can someone pls add the patch to mainline for 4.4.2 if it works?

We need to add patch to the mainline.

So this small nasty bug is here for almost two year. Will it be fixed in SC 4.5? Anybody knows???

Good question...

I mean 110 votes and two years gone and the bug is still there :/

I'm note hopefully that they ever fix the bug :/

So, still persist in KDE SC 4.5.0. This is really hopeless. Is there anybody able to fix this?
