When I try and run any app or tab auto complete it says I'm out of space ex. -bash: cannot create temp file for here-document: No space left on device

But when I run df -h it says I have 67% space used

Filesystem                      Size  Used Avail Use% Mounted on
udev                            7.8G     0  7.8G   0% /dev
tmpfs                           1.6G  1.2M  1.6G   1% /run
/dev/mapper/minecraft--vg-root   48G   31G   15G  67% /
tmpfs                           7.9G   20K  7.9G   1% /dev/shm

/dev/sda1                       719M  139M  544M  21% /boot
tmpfs                           1.6G     0  1.6G   0% /run/user/1000

Here is df -ih

Any help would be help full

    Did you also check the inode usage - as suggested here for example [bash: cannot create temp file for here-document: No space left on device](https://askubuntu.com/questions/948722/bash-cannot-create-temp-file-for-here-document-no-space-left-on-device) – steeldriver Jul 16 '23 at 17:46
  • @steeldriver I updated the post to include the inode stuff – Colin Sutter Jul 16 '23 at 17:50

    You've run out of inodes - meaning you have too many files on the disk. – Artur Meinild Jul 16 '23 at 17:51
  • https://askubuntu.com/questions/231585/running-out-of-inodes. So you are out of storage - just not space, but rather "reference points" (inodes). – Artur Meinild Jul 16 '23 at 17:51
  • thank you both for helping me find the problem – Colin Sutter Jul 16 '23 at 18:05

    I've added an answer to the duplicate post, explaining how to reformat your filesystem with more inodes. https://askubuntu.com/a/1478154/1066942 – Artur Meinild Jul 16 '23 at 18:17
  • [Ubuntu 18.04 LTS has reached the end of it's *standard* support life](https://fridge.ubuntu.com/2023/05/13/extended-security-maintenance-for-ubuntu-18-04-bionic-beaver-begins-31-may-2023/) thus is now off-topic here unless your question is specific to helping you move to a *fully supported* release of Ubuntu. Ubuntu 18.04 ESM support is available, but not on-topic here, see https://askubuntu.com/help/on-topic See also https://ubuntu.com//blog/18-04-end-of-standard-support – guiverc Jul 16 '23 at 22:12
  • When you create the file-system (*format* time) you give details and set size limits. Defaults work for most circumstances assuming sufficient maintenance is done on the system, but defaults won't work for all situations. – guiverc Jul 16 '23 at 22:14
