I would say your error is not related to Mono, but to the access
privileges on your machine. Please look into the privilege settings of
the file which causes the error. If it looke somehow like -rw-------,
only root and nobody else can read and write it. Then you'll have to
change it to -rw-r--r--, so that an ordinary user can at least read it,
and retry.

A cleaner solution, however, would be to generate a separate keypair
for each user and store it in $HOME/.mono/keypairs, so that you won't
run into privilege issues.
