+Version 8.20210223 is quite old, it would be good to try with a newer
+version and see if the error message is different.
+
+You might also try strace and look to see what it says happens when it
+tries to open "repo/.git/annex/keysdb/db".
+
+I don't know if what you showed about file permissions means you can really
+read it. There might be ACLs or other complications? The best way to show
+you can read it is to actually try to read it, eg `cat db >/dev/null`
