package Install issues - solved?

[mervincm]

In an attempt to test my Realtek NIC stability I have tried to install the iperf package from the package manager. Under available packages is a quite a bit older package for 2.0.5.5_3. regardless it is good enough for my purposes, so I attempted to install it via the GUI, and got an error.

pfSense-pkg-iperf installation failed!

searching the forum, I saw advice that you could install v3 via ssh command line (I didn't know there were any packages not in the package manager!) so I tried that. (pkg install iperf3) I got another sort of error

pfSense-core repository is up to date.

at this point I am wondering if something is wrong with my packaging, so I followed the advice in the documentation on fixing a broken pkg database, and that seemed to go bad as well ...

/root: /bin/mkdir -p /var/db/pkg/ /root/var/db/pkg/
/root: /usr/sbin/pkg-static update -f
/usr/sbin/pkg-static: Command not found.
/root: /usr/sbin/pkg-static install -yf pkg pfSense pfSense-kernel-pfSense
/usr/sbin/pkg-static: Command not found.
/root: /etc/rc.php_ini_setup

afterwards I tried to install another simple package (cron)

pfSense-pkg-Cron installation failed!

Strangely, I was able to upgrade an existing package

pfSense-pkg-acme reinstallation successfully completed.

and

pfSense-pkg-openvpn-client-export reinstallation successfully completed.

not knowing really how to handle this I reverted to my IT crowd training and turned it off and on again.

this time

pfSense-pkg-iperf installation successfully completed.

and since why not I tried the iperf3 package and this time..

so, other than to add my experience for the next person .. any ideas why I could reinstall existing packages, but not install new ones, and a simple reboot fixed it?
