A year later I am running into exactly the same issue. I just started today to explore M2P.
I used the latest downloadableimage and am now on Version 2.51.
Is it still expected that I have to manually update libcrypt-openssl-rsa-perl?
Or am I supposed to somehow trigger an apt-gt update anyway?
Even when just updating the single package the list of updated dependencies is quite long.
domus1024, thanks for the hint!
