[SOLVED]How to mount disks in Nemo without entering password?

silver-lasombra · 2024-08-27 06:45:56

I used cinnamon desktop and Nemo filemanager.
When I tried to mount disks by clicking in Nemo, it asked me to enter the password.
However in Linux Mint password is not needed.
How should I do to mount disks in Nemo without entering password, just like the same in Linux Mint?

nemo uses udisks and if that asks you for a password w/o you messing around w/ polkit the most likely cause is a degenerated session.

loginctl session-status

If you're using dbus-launch anywhere: don't.
If you're using startx/xinit - please post your xinitrc, it's likely broken (see last link below)

I find out that I'm using dbus; but I couldn't understand what I should do next. Could you make it more clearly?

Of course you're using "dbus", that's not the same as dbus-launch.
Post the requested outputs and files

loginctl session-status
cat ~/.xinitrc
echo $DBUS_SESSION_BUS_ADDRESS
ps aux | grep dbus

Do not mess around w/ polkit!
The default policy in /usr/share/polkit-1/actions/org.freedesktop.UDisks2.policy grants active users to mount things.

=> Fix your session, start by posting the output of the commands in #4

By the way, since I'm the only user of my PC, overwrite the default polkit rule maybe shouldn't be a problem?

The problem isn't so much security as that a broken session has wider implications.

That being said, you're starting the session w/ lightdm, not xinit, the session is active, $DBUS_SESSION_BUS_ADDRESS as expected, there's no extra dbus daemon/launch (at-spi aside)

But
1. Service: lightdm-autologin
What if you do not login automatically?

2.

1.After I disabled autologin and reboot, lightdm-slick-greeter didn't show up, with only a black screen left(and a short bar flashing on the top-left of the screen)
Switching to tty is almost impossible because it force me to jump to tty7 after I use ctrl+alt+(from f2 to f6).
I had to boot from arch live CD and install lightdm-gtk-greeter(which is conflicted with previously installed mint-artwork).
After that I repeat #4, this is the log: (seems nothing changed)

2. Yes because I need to go to /etc/polkit-1/rules.d to disable the rule I set in #5. I only ran Nemo as root for this and didn't do any other things.

I'd not expect any output to change here (that looks actually as expected and fine) but the question is whether w/o the autostart, nemo/udisks2 is now treated for an active session (ie. whether you can mount external drives/partitions w/o being asked for authentication)

Also, to get nemo out of the equation here, can you

udisksctl mount -b /dev/sdb1

(provided you've eg. plugged a usb key and there and it actually is sdb1)

silver-lasombra · 2024-08-31 14:32:27

It ask me for password:

After entering password it mounts as usual:

$ udisksctl mount -b /dev/sdb2

That's not expected, so it's not a nemo-specific problem.

=> Udisks2, lightdm or cinnamon's fault.

Boot the multi-user.target (2nd link below), log into a tty and try "udisksctl mount -b /dev/sdb2" from there.
If that works, install xorg-xinit, cp /etc/X11/xinit/xinitrc ~/.xinitrc, edit ~/.xinitrc and insert "exec cinnamon-session" before the "twm &" line (the script will end with that call, you can ignore the tail)
The run startx, should start cinnamon - try to mount the drive there.
If that works, post you lightdm config…

silver-lasombra · 2024-09-01 01:01:21

Still need password...
tty need password

seth · 2024-09-01 08:13:53

Can you "systemctl reboot" w/o being asked for your password (careful, obviously this will reboot the system and you migth not have to issue credentials)?
Otherwise please post your shellrc (~/.bash*, I guess)

Yes, it reboot immediately without password needed.

pacman -Qikk udisks2

To be clear: what you're trying to mount is some external media?
Because

  <!-- mount a device considered a "system device" -->
  <action id="org.freedesktop.udisks2.filesystem-mount-system">
    <description>Mount a filesystem on a system device</description>
    <message>Authentication is required to mount the filesystem</message>
    <defaults>
      <allow_any>auth_admin</allow_any>
      <allow_inactive>auth_admin</allow_inactive>
      <allow_active>auth_admin_keep</allow_active>
    </defaults>
  </action>

is normal (the polkit override you picked up from EOS steamrolls over both) and the correct-ish to manage internal/system partitions is via fstab.

udisks might have a different perception of the nature of the drive…

LC_ALL=C udisksctl info -b /dev/sdb1 # |grep HintSystem, but the rest might reveal why there'd be disagreement

There was https://bbs.archlinux.org/viewtopic.php … 6#p2172566 - but actually the other way round (internal drives detected as removeable because of hotplugging support)

Edit: in better news, your session is fine - sorry for chasing you down that road but it's the common breakage

No, it's internal partitions. Now it's a virtual disk in a virtual machine, and it will be a partition of an internal SATA SSD as mentioned below. Maybe there will also be an HDD.

Because I plan to install Windows and Arch dual boot, and since this is the first time I use Arch, I decide to try in VMware first.
The disk will be 3 partitions, one is Win, one is Arch and one is public data for them.
I don't want to mount the public data partition via fstab, because if I do something stupid like 'sudo rm -rf /*' by accident, the automatically mounted data partition will lost. I just want to mount it only when needed.

I checked out Archwiki again. The rules mentioned in Udisks wiki page meets my need best (similar to rules mentioned in #5 and I shall choose the one mentioned in archwiki).

Thank you for spending so much time.

https://man.archlinux.org/man/core/util … fstab.5.en - that's what the noauto entry is for. It allows you to mount the partition at will.
You can also use systemd features to implicitly mount it when the path gets accessed (though idk what's gonna happen for your disaster-command) and automatically unmount it after some time.
