Can you share following

apt show libmpc3

# apt show libmpc3

how does it behave if you install it manually

apt update
apt install libmpc3
7 
apt update
apt install libmpc3

The following information may help to resolve the situation:

ok let’s check next one

apt show libmpfr6

apt show libmpfr6

apt show -a libmpfr6

strange, can you share following

apt policy libmpfr6
12 
apt policy libmpfr6

libmpfr6:
  Installed: (none)
  Candidate: (none)
  Version table:
     4.2.0-1 -30000
        500 https://ftp.debian.org/debian bookworm/main arm64 Packages
13

Something or someone reduced priority down to -30000. Therefore package is not going to be installed.

I have a feeling what is could be. Please check related configs:

for i in /etc/apt/preferences{,.d/*}
do
[[ -f "$i" ]] || continue
echo "$i:"
cat "$i"
done
15 
 for i in /etc/apt/preferences{,.d/*}
do
[[ -f "$i" ]] || continue
echo "$i:"
cat "$i"
done

/etc/apt/preferences.d/apt-listbugs:

Hope there is a solution indeed priority down to -30000

Of course. Looks like you have installed apt-listbugs

Have a look at similar GitHub post Cant install Netdata · Issue #7132 · MichaIng/DietPi · GitHub
