Mac OS Venture Update asks for MacPorts password, password unknown

[ChristianPfeiferPhD]

Dear MacPorts Community,

I am facing the following problem.

I migrated an older MacBookAir (2013, OS Mojave 10.14, Intel) to a new one (2022, OS Ventura 13.0, M2 Chip). Now when I want to install a OS update to 13.1 the system wants a password related to MacPorts from me, which I do not have.

How can I reset the password?

I tried to uninstall macports, which however also did not work. The terminal displays

dlopen(/opt/local/share/macports/Tcl/macports1.0/MacPorts.dylib, 0x000A): tried: '/opt/local/share/macports/Tcl/macports1.0/MacPorts.dylib' (fat file, but missing compatible architecture (have 'x86_64,i386', need 'arm64')), '/System/Volumes/Preboot/Cryptexes/OS/opt/local/share/macports/Tcl/macports1.0/MacPorts.dylib' (no such file), '/opt/local/share/macports/Tcl/macports1.0/MacPorts.dylib' (fat file, but missing compatible architecture (have 'x86_64,i386', need 'arm64'))

while executing

"load /opt/local/share/macports/Tcl/macports1.0/MacPorts.dylib"

("package ifneeded macports 1.0" script) invoked from within

"package require macports"

(file "/opt/local/bin/port" line 38)

Thanks for the help.
