The error indicates that the ollama launch opencode command is failing because it cannot create a backup file in /tmp/ollama-backups/ due to permission denied on the target directory or file.

How to Solve This

1. Check /tmp Permissions

• /tmp is typically world-writable, but sometimes restrictions apply (e.g., on shared systems or custom configurations).
• Run:
  bash

  Copy

  ls -ld /tmp

• If /tmp is not writable by your user, contact your system administrator.

2. Create the Backup Directory Manually

• Try creating the directory yourself:
  bash

  Copy

  mkdir -p /tmp/ollama-backups/
  chmod 755 /tmp/ollama-backups/

• Then retry the ollama launch opencode command.

3. Use a Different Backup Location

• If /tmp is restricted, specify a different directory for backups.
• Set the TMPDIR environment variable to a writable location:
  bash

  Copy

  export TMPDIR=$HOME/tmp
  mkdir -p $TMPDIR
  ollama launch opencode --model qwen3.6

4. Run as Root (Not Recommended)

• If you have admin rights and are sure about the action, try:
  bash

  Copy

  sudo ollama launch opencode --model qwen3.6

• Warning: Running as root can be risky. Only do this if you understand the implications.

5. Check for Existing Backups

• If /tmp/ollama-backups/ already exists but is owned by another user, either:
  • Delete it (if safe):
    bash

    Copy

    sudo rm -rf /tmp/ollama-backups/

  • Or change ownership:
    bash

    Copy

    sudo chown -R $USER:$USER /tmp/ollama-backups/

Next Steps

Try option 2 or 3 first. If the issue persists, check the exact permissions of /tmp and the backup directory.
