Not worthless. The coinage had intrinsic value, being made of metals with a commodity value. So it’s not like holding a paper banknote when a government collapses. People would still have used them to hoard savings, for trade and melted down as a source of precious metals.
That was really the only value they ever had. Boosted a bit by confidence in the purity (but also reduced when Rome debased its coinage).
Is it possible that you didn’t enable snapshots during installation of TW, and then turned it on later?
That seems to be a common explanation on the openSUSE forum when .snapshots is missing from fstab (found by searching for the error you are hitting). There are some threads with workarounds. Basically, mount the .snapshots subvol manually, re-try the rollback and then add .snapshots to fstab so it works in the future.
Just tried this on a recent Trixie amd64 install.
locateisn’t installed by default, but there is alocate/stable 4.10.0-3package and it installs just fine for me.sudo apt update sudo apt install locate
