Hello,
error: Package requirements (libosmocore >= 1.3.0)
were not met:
libosmocore has already been the newest version (0.9.0-7)
it's obvious that your libosmocore is too old. I guess you're using a
non-official package repository with ancient unmaintained packages.
Osmocom provides up to date nightly [1] and latest release [2] binary
packages for Debian-based distributions. You should remove your old
package and use the one from Osmocom's repository. Or simply build the
recent libosmocore yourself.
