Can't install app, discovery says: not enough space

Help
1

Although there is still 25GB of free space (VirtualBox machine), Discovery reports that I don’t have enough space to install an app (LibreOffice).

Note: At first, there wasn’t enough space, so I increased the partition size in VirtualBox – Media and then, after restarting, allocated the unallocated space to the partition. I still can’t install any apps!

Can you show the output of df -h ?

I’m wondering if you need to expand the btrfs filesystem inside the newly enlarged partition.

By the way, why does Dolphin display such a strange size specification?

So your / is almost full.

If you enlarged the partition, did you also take the next step of enlarging the btrfs filesystem to fill the partition?

run0 btrfs filesystem resize max /

From what I can see, it’s displaying the same data as df -h ?

Thanks.
That was the problem. It’s too bad Dolphin doesn’t make it clear what the problem is.
