@MaskedMan Can you post a screenshot?

Masked Man

19:34

@MarkYisri, post a screenshot of what?

user.dz

19:47

@MaskedMan hi, busy?

1 hour later…

Masked Man

20:53

@user.dz,hi, sorry for delay :)

user.dz

21:17

@MaskedMan, last time i was looking to ask you about :
`gvfs-mount --eject "file:///media/$USER/DISK_LABEL" `

Masked Man

give me a sec

user.dz

Masked Man

it's not working

the hard keep on spinning after gvfs-mount --eject

user.dz

21:37

Does it remove the /dev node

Masked Man

user.dz

which one , or all?

Masked Man

no one

user.dz

Masked Man

it does not remove anything

I think it relates to udev rules

user.dz

21:38

why?

Masked Man

cause when I safely remove it, it goes to be powered off but immediately is remounted

user.dz

let's check

run for that disk , sdb/ sdc ..

udevadm info /dev/sda

Masked Man

sda or sdb?

user.dz

Check it with

sudo fdisk -l

Masked Man

I know it's mounted as sdb

so run udevadm info /dev/sdb?

user.dz

21:43

yep

Masked Man

Here's the output: link

user.dz

then

udevadm test /devices/pci0000:00/0000:00:14.0/usb4/4-1/4-1:1.0/host7/target7:0:0/7:0:0:0/bloc‌k/sdb

Masked Man

It exited with error code 4

rules contain 393216 bytes tokens (32768 * 12 bytes), 36200 bytes strings
24247 strings (204685 bytes), 20679 de-duplicated (172054 bytes), 3569 trie nodes used
unable to open device '/sys/devices/pci0000:00/0000:00:14.0/usb4/4-1/4-1:1.0/host7/target7:0:0/7:0:0:0/bloc‌k/sdb'
Unload module index
Unloaded link configuration context.

user.dz

weird?

is there any partition mounted ?

Masked Man

You mean external drive partitions?

Yes

I was using HD just now

user.dz

21:50

I was expecting some like this

paste.ubuntu.com/23559947

I think i found something

your disk is detected as ATA (internal)

mine is USB (external)

now i think you right about udev

and i believe it is related to that error
`It exited with error code 4`

you have a corrupted/broken rules file.

Masked Man

So what should I do?

user.dz

let me see udev manual if there a verbose option

which tell more debug info

ls -l /etc/udev/rules.d/

Masked Man

22:08

total 0

user.dz

ls -l /lib/udev/rules.d/

Masked Man

output here

user.dz

Could you get them sorted with name?

It's hard to compare them when sorted by date

Masked Man

how to do it?

user.dz

it hte default

may be you have custom settings

let me check

Masked Man

22:16

yeah

I did some modification

I'll post the sorted now

user.dz

Masked Man

check here

user.dz

yeah better

Masked Man

I had to restart my computer, how can I access shutdown logs? It informed me about swap in my external HD!

user.dz

all logs in /var/log/

Masked Man

22:21

I'm missing messages

there

user.dz

I didn't get your point ?

Masked Man

in /var/log/ should be a messages file, should not?

user.dz

dmesg

kern.log

you mean these?

Masked Man

I think yes

user.dz

you should have one dmesg and some kern.log.X

+ some syslog.X

Masked Man

22:27

yes

which one is for the last reboot?

user.dz

either wihtout number or .1

Masked Man

it does not include what I saw on screen when Ubuntu was restarting

user.dz

ok, you mean then the systemd journal

journalctl but i don't know well

Masked Man

Thanks

user.dz

why do you have virtualbox rules ?

Masked Man

22:43

I have virtualbox

user.dz

i have too but no rules should be there

could you run

dpkg -S 40-bridge-network-interface.rules 40-usb-media-players.rules 55-dm.rules 60-qemu-system-common.rules 60-virtualbox-dkms.rules 60-virtualbox.rules 60-xdiagnose.rules 61-gnome-bluetooth-rfkill.rules 95-kpartx.rules

Masked Man

what does it do?

user.dz

check which package install these rules

Masked Man

`bridge-utils: /lib/udev/rules.d/40-bridge-network-interface.rules
media-player-info: /lib/udev/rules.d/40-usb-media-players.rules
dmsetup: /lib/udev/rules.d/55-dm.rules
qemu-system-common: /lib/udev/rules.d/60-qemu-system-common.rules
virtualbox-dkms: /lib/udev/rules.d/60-virtualbox-dkms.rules
virtualbox: /lib/udev/rules.d/60-virtualbox.rules
xdiagnose: /lib/udev/rules.d/60-xdiagnose.rules
gnome-bluetooth: /lib/udev/rules.d/61-gnome-bluetooth-rfkill.rules
kpartx: /lib/udev/rules.d/95-kpartx.rules`

user.dz

this a real machine (not virtual right?)

Masked Man

22:46

Yes

user.dz

sudo apt purge virtualbox-dkms

it is for guest systems not the host

Masked Man

what is virtualbox-dkms?

user.dz

wait

Masked Man

I purged that :|

user.dz

you could reinstall it , excuse me i mixed it with virtualbox-guest-dkms

Masked Man

22:50

no problem

user.dz

so all rules have packge

it hard to find the which file created the issue

I will think about and let you know

Masked Man

Keep in mind that I could not safely remove it in a live Ubuntu either (without any extra package installed)

thanks

I'll be back tomorrow

Good night :)

user.dz

so you mean the rules have a bug

Good night, c u tomorrow
