# Ubuntu – No space left on device even though there is

aptdiskdisk-usage

A laptop with broken screen that I access via SSH. The sudo apt-get autoremove command gives me the following errors

cp: error writing ‘/tmp/mkinitramfs_zN6ZvT//lib/x86_64-linux-gnu/libpthread.so.0’: No space left on device
cp: failed to extend ‘/tmp/mkinitramfs_zN6ZvT//lib/x86_64-linux-gnu/libpthread.so.0’: No space left on device

I get similar errors from various other commands but gparted tells me there is more than 20GB space left on the (single) partition on the laptop. Here is the output of df

Error started after I ran sudo apt-get upgrade.

sudo umount /tmp
