This question already has an answer here:

I get an error saying that I do not have enough space on /tmp to download a file. However, I have around 900 Mb of free space on the / partition. Is there a way for Ubuntu to actually use this space?

Here is the result of df -h:

Sys. de fichiers Taille Utilisé Dispo Uti% Monté sur
udev               1.8G     12K  1.8G   1% /dev
tmpfs              351M    1.3M  350M   1% /run
/dev/sda5           19G     18G     0 100% /
none               4.0K       0  4.0K   0% /sys/fs/cgroup

none               1.8G    352K  1.8G   1% /run/shm
none               100M     32K  100M   1% /run/user
/dev/sda2          923M    250M  611M  29% /boot
/dev/sda4           91G     29G   58G  33% /home
overflow           1.0M    448K  576K  44% /tmp

and here is the lsblk result:

sda           119.2G
├─sda1 swap     7.5G [SWAP]
├─sda2 ext4     954M /boot
├─sda3            1K      
├─sda4 ext4    92.2G /home
└─sda5 ext4    18.6G /

    Your drive is showing 100% utilization. Chances are that they OS is using that last gig of space to run in.. It needs space for its own temp files that grow and shrink. – John Orion May 23 '16 at 11:40
  • @Clément Also look at how you have an 'overflow' type of item for /tmp. Usually, this is also indicative of a 'full disk' as overflow is a tmpfs (which sits in RAM, really). I would suggest a much larger / partition as well, at least 30 - 40GB, if you intend to use it and install things on a daily basis outside of /home – Thomas Ward May 23 '16 at 11:44
  • If you want a quick fix you can run sudo apt autoclean and you can delete the cache directory from software downloads which may give another gig or so.. sudo apt clean – Bhikkhu Subhuti May 23 '16 at 11:49
