Cannot install or update via zypper dup or YaST

Please let me know what system information you need to be able to help.
Thank you for the help

# zypper dup
The target filesystem is mounted as read-only. Please make sure the target filesystem is writeable.

Is the root file system full?

Check the output of

df /

If you are using "btrfs" (likely), then check the output of:

btrfs filesystem df /

And of course check if there are any file systems mounted read-only

mount

This is the first time I have installed with btrfs.
There are some things I am not familiar with.
If there is anything that needs to change, please let me know.

This one:

/dev/sda3 on / type btrfs (ro,relatime,space_cache,subvolid=266,subvol=/@/.snapshots/1/snapshot)

But why? So YaST is only reporting the truth and of course can not write to a ro file sytem

I am no Btrfs user. But looking in the logs might help. Maybe browse through

dmesg

Some 3 GiB free may not be enough for a "zypper dup", then the system went read-only to avoid corruption?
Maybe deleting some snapshots might fix things.

Maybe deleting some snapshots might fix things.

This is my first try with btrfs.
How do I remove the snapshots?
How do I limit them?
