-RAM to 10GB or 12GB but for me it worked by only using 8GB of RAM for this VM.
 
 ### Modify <kbd>/etc/fstab</kbd> and increase <kbd>/tmp</kbd>
 
 To increase <kbd>/tmp</kbd> we log into the VM and modify the file <kbd>/etc/fstab</kbd>.
 
 ```fstab
-tmpfs /tmp tmpfs size=6G,nr_inodes=10k 0 0)
+tmpfs /tmp tmpfs size=10G 0 0

+Alternatively you can use another directory with more space as tmp storage:

+```console
+$ TMPDIR=/var/lib/libretranslate/tmp pip install --prefer-binary libretranslate
