[SOLVED] Method mirror has died unexpectedly!

[effemmeffe]

Today I saw a message in XBMC telling me that there is some package upgrade available, so I went on my Mac a opened a ssh session and got this error:
xbian@xbian ~ $ sudo apt-get update
Hit http://archive.raspberrypi.org wheezy Release.gpg
Hit http://mirrordirector.raspbian.org wheezy Release.gpg
Hit http://archive.raspberrypi.org wheezy Release
Hit http://mirrordirector.raspbian.org wheezy Release
E: Method mirror has died unexpectedly!
E: Sub-process mirror received a segmentation fault.
xbian@xbian ~ $


Any idea on what's wrong?

Can you do a sudo apt-get update first?

At the end I found the problem: my sd was full. I removed some files from /home/xbian and now I'm able to update & upgrade.
But the problem just changed: why is my 8G SD is (now almost) full?

adding the biggest directories I am hardly near to 8G.
I found in the forum an user which had the same issue and I copied the command line he used:

Apparently there are no reason for my sd to be full.
I also checked and the partition is already resized to maximum.

Any help? I'm drowning here...

Try a sudo apt-get clean, there seems to be a lot of content in your /usr folder

[effemmeffe]

did it, i went from 37M free to 72M free:

Code:

xbian@xbian / $ df -h

solved: it was a cronjob that tries to write a full sd backup on a network share. if the network is not available the cronjob creates the file on a directory with the same name of the mountpint, then when the network share is available again the file is hidden.

do a test before you do the backup. you can test for mountpoint existence like this:

mountpoint -q /path/to/network_mount || { echo "network not available"; exit 1; }

this way the script will exit without trying to backups if the network share is not mounted.

( ... nicer output "du -xhd1 /" -x will not descent into different filesystem (mount), -h human readable numbers (G/M/K), -d deepness level)
