Unable to upgrade to 6.7.0-rc2

Any  idea why your rootfs is so small? Here is my df for comparison.

You might try rebooting to see if it goes back to normal

 

Isn't the max size of root fs 50% of available memory? Which means that the system has 2G of memory, which is basically nothing nowadays.

I think you need a minimum of 4GB RAM to successfully upgrade via the Wub GUI

Yes, it's a VM with 2Gb.

 

Used to be able to upgrade normally, up until this release.

 

I'll set aside 4Gb for the VM.

 

Thanks a lot !
