Can't upgrade to 1.16.1

Help Section
#1

start the upgrade with OctoPkg; after fetched all packages and began to install-extract them, here are the first red messages:

[20/281] Upgrading libgpg-error from 1.39 to 1.41…

at the point of

a warning windows tells:

click on OK

and try to start the upgrade again then

"Starting package upgrade…

ld-elf.so.1: Shared object “libicui18n.so.67” not found, required by “libQt5Core.so.5”

Command finished with errors!"

and the system becomes unusable, non more applications can be opened.
How to get out from there?
Thank you

Could you please explain what you want to upgrade to 1.16.1?

What does freebsd-version -uk return?

#3

you can see:

with sakura
su
pkg delete -f librsvg2
pkg lock -y consolekit2-1.2.1_1
pkg lock -y e2fsprogs
pkg upgrade

Hi, forgot to tell that system is a full installation on a volume, not live usb.
Just accepted the package upgrade proposed in OktoPkg
"There is one outdated package in your system:
Name
Outdated version
Available version
pkg
1.15.10
1.16.1 "

mauro@NomadBSD ~> freebsd-version -uk
12.1-RELEASE-p6
12.1-RELEASE-p6

I made the upgrade by sakura using the command you’ve indicated, the upgrade goes well to the end, but then the system behaves weirdy (applet tray icons disappear, shutdown gadget not working when clicked). the upgrade is from 1.15.10 package to 1.16.1 as written before

I have the live persistent usb and I get the same. Upgrade or an install breaks NomadBSD for me.
