6.42rc37 CCR Disk full - can't upgrade

Hey!

I am having a weird issue with my CCR - I was trying to upgrade but I found that I have like 9MB free although I have no files in /files, I am not using dude or user manager (which are known to generate lots of log as far as I found here)… I am also not using any additional packages I could uninstall. Is there something obvious I missed? Where is the free space taken? Where can I monitor any space usage taken by files which are not listed in ‘/files’ and how can I free up the space (which is not taken by anything important otherwise I’d know…)?

Thanks for any help!

Hey,
To what version of ROS are you trying to upgrade?

Tried 6.43.rc12 and 6.42.1 but both require 15MB free…

You could try upgrading through a Netinstall, as i think your total HDD size is somewhat less than it should be, that should fix the issue.
