Only if you tried the unstable branch or lmdb branch. If you were always on master, it is not an issue. If you tried unstable or lmdb, you should remove the lmdb director and re-import from sqlite.
It sounds like a bug though, just not happening to everybody.
Interesting...I have another computer MacOS and it works fine there...I have not done anything different while updating. I will dig into it a bit on the other machine and see what is going on.
From the computer it works it was updating from below...
From https://github.com/mikedilger/gossip
e88cfe5..39d64a4 master -> origin/master
e88cfe5..5c61905 unstable -> origin/unstable
Where is the lmdm directory…I don’t see it. Below is all I can see. 
Wait…found these 2 in target/build…is that what I should delete
lmdb-rkv-sys-d9e52b79a4e3f566
lmdb-rkv-sys-e428970c930e8535
This is fixed now, but for future reference we use this directory:
https://docs.rs/dirs/latest/dirs/fn.data_dir.html
and append "gossip/" afterwards. Then we append "lmdb/" after that for the lmdb database.
thanks Mike
Tried a clean re-install…still getting the error
