"Read-only file system" errors during install

[Daniel Richard G.]

Binary package hint: libsensors4

This concerns libsensors4 version 1:3.0.2-1ubuntu2 in Intrepid.

On installing libsensors4 for the first time, I see the following (excerpted) in the output of apt-get:

See bug #270043 for a similar problem reported against mdadm.

[ceg (ceg)]

seems or seemed to be a general issue with dpkg or udev or something (search bugs with "rm: cannot remove")

[james (james-nurealm)]

Yes, this bug effects more than one person. No, I haven't tested a version newer than Intrepid.

Trying:

sudo MAKEDEV -v fd0

repeated failures, similar to:

...

create fd0u1600 b 2 124 root:floppy 0660

rm: cannot remove `fd0u1600-': Read-only file system

mknod: `fd0u1600-': Read-only file system

makedev fd0u1600 b 2 124 root floppy 0660: failed

rm: cannot remove `fd0u1600-': Read-only file system

"makedev" is the function in the /sbin/MAKEDEV script.

ls -ld /dev

drwxr-xr-x 15 root root 14660 2010-06-18 10:43 /dev/

mount

...

udev on /dev type tmpfs (rw,mode=0755)

...

sudo touch /dev/test

ls -l /dev/test

-rw-r--r-- 1 root root 0 2010-06-18 11:56 /dev/test

sudo rm -v /dev/test

removed `/dev/test'

ls -l /sbin/MAKEDEV

-rwxr-xr-x 1 root root 53290 2010-06-18 11:49 /sbin/MAKEDEV*

sudo MAKEDEV -V

This is Debian MAKEDEV. For version info, try 'dpkg --list makedev'

See /usr/share/doc/makedev/ for more information on Debian MAKEDEV.

cat /proc/mounts

...

udev /dev tmpfs rw,mode=755 0 0

...

Something about "tmpfs" maybe?

This works though:

cd

sudo MAKEDEV -v fd0

...

sudo mv fd0* /dev
