You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libmbedtls10 : Depends: libmbedcrypto1 (>= 2.7) but it is not going to be installed
libmbedx509-0 : Depends: libmbedcrypto3 (>= 2.14) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

api-trace {
This stanza controls binary API tracing. Unless there is a very strong reason,
please leave this feature enabled.
on
Additional parameters:
To set the number of binary API trace records in the circular buffer, configure nitems
nitems
To save the api message table decode tables, configure a filename. Results in /tmp/
Very handy for understanding api message changes between versions, identifying missing
plugins, and so forth.
