Issues after installing latest PostMarket OS with POSH

[xen314]

Have dragged the PinePhone out of the cupboard to give it another try.
Have tried to install the Latest version of PostMarket OS to both EMMC and the SSD card.

The install was very easy but upon boot I get
can't create directory '/home/user/local/' :read only file system

then a string similar errors around cannot create files due to read only file system.

Would seem Postmarket Os has installed with a Read only filesystem.

Any ideas how to fix this?

thanks
