Running out of disk space on Ubuntu? I’ve been getting low disk space warnings on a 40GB Ubuntu partition . The usual tips to free space on Ubuntu weren’t enough, so I opened Disk Usage Analyser – or run sudo du -sh /var/lib/snapd – and found nearly 8GB was eaten up by old snap versions. This will remove old snap versions and free up disk space. As installed snaps update, old versions are retained and you’ll eventually need to do repeat this again.
