I've had this machine for about a month, and after trying the daily build from the minefield about once a week, and i keep getting this error. xxxxx (read-only filesystem) buffer I/O error on device loop0 logical block xxxx at least that's as well as i can remember, not knowing any way to access a logfile. it seems to install properly, reboots, and seems to be nearly finished loading when i get this error. This is still present in Wubi 8.04 rev 459 using amd64 on real (cheap) hardware. Additionally, while i doubt this is related, i've also been unable to install the Ubuntu 8.04 beta (x64) from the live cd to a real partition, as it hangs after the migration assistant.

Even mouting with 'sync','data=writeback' does not help. I tried to losetup a device, but see the same behavior.

Are there any ways to get rid of the loop device? linux ubuntu mount share|improve this question asked May 4 '11 at 9:13 BiX 1271113 That's odd, you don't usually attach loop to usb devices. How did you do that? –Keith May error on device 4 '11 at 9:15 I was using LUKS encryption and thought I could encrypt my 1gb usb flash drive. –BiX May 5 '11 at 1:30 You can use LUKS for that, but not by using loop device. A LUKS partition has its own partition type. –Keith May 5 '11 at 2:37 Sorry noobness on my part, cannot find any clear instructions online. –BiX May 5 '11 at 3:20 Ask a new question. ;-) –Keith May 5 '11 at 5:04 add a comment| 6 Answers 6 active oldest votes up vote 7 down vote accepted are you sure, that the device isn't busy? Have you ever tried fuser to determine an possible PID? Precautionary get all possible informations: fuser -c /dev/loop0 fuser -d /dev/loop0 fuser -f /dev/loop0 try to stop the process, which could use /dev/loop0 if necessary use kill -9 or: try fuser -k to send the kill signal -> look at man fuser share|improve this answer answered May 4 '11 at 10:52 The Bndr 5,59273468 add a comment| up vote 25 down vote You may have to also use dmsetup to remove the device mapping. Easiest way, if it doesn't interfere with any other mappings is to use a dmsetup remove_all. share|improve this answer edited May 21 '15 at 21:30 A.D. 1,87511941 answered Jun 21 '12 at 0:38 Aaron Flin 25932 6 This worked for me,

You created (as root) a directory, then changed directory to the HOME directory of the logged-in user, then tried to mount the wildcard ubuntu-* over the root directory. The wildcard ubuntu-* did not match anything in the current directory, and mount told you. What were you trying to do? –waltinator Jun 10 '15 at 5:56 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote First make sure you have mounted loop device kernel module. So run: lsmod | grep loop If you get no output, that means you have to mount the loop device kernel module . So: modprobe loop Re-run the following to make sure the module is loaded. You should get some outputs: lsmod | grep loop Now, to mount an ISO file as loop device do the following: mount -o loop -t iso9660
