# Free Up Space on Ubuntu
\
### 1. Clean the APT Cache (and do it regularly)
> Check how big your apt cache is
```bash
sudo du -sh /var/cache/apt/archives
```
> Clean the apt cache
```bash
sudo apt-get clean
```
\
### 2. Remove Old Kernels (if no longer required)
```bash
sudo apt-get autoremove --purge
```
\
### 3. Get rid of packages (if no longer required)
```bash
sudo apt-get autoremove
```
\
### 4. Clear systemd journal logs
> Check the log size
```bash
journalctl --disk-usage
```
> Clear the logs that are older than a certain days (3days in this example!!)
```bash
sudo journalctl --vacuum-time=3d
```
\
### 5. Clean the thumbnail cache
* Ubuntu automatically creates a thumbnail, for viewing in the file manager.
* It stores those thumbnails in a hidden directory in your user account at the location \~/.cache/thumbnails.
> Check the size of thumbnail
```bash
du -sh ~/.cache/thumbnails
```
> Clear the thumbnail cache (every few months or so!)
```bash
rm -rf ~/.cache/thumbnails/*
```
