Libcrypt.so.1 error after dist-update on Debian

Question

I have the following problem:

I was updating debian on my lenovo laptop from distro 4.19 to latest.

During upgrade the shell give me an error then I can't use sudo or su due authentication error.

So I rebooted and I need to boot in recovery mode.

I tried to do a apt--fix-broken install

But I get this error:

enter image description here

/usr/bin/python3: error while loading shared libraries: libcrypt.so.1: cannot open shared object file: no such file or directory E: Sub-process /usr/bin/apt-listchanges --apt || test$? -lt 10 returned an error code (1) E: failure running script/usr/bin/apt-listchanges --apt || test $? -lt 10

Actually I have a Debian 4.19.152-1 distro x86_64

I can't connect on internet cause dhcp server isn't installed.

Can u help me?

Thanks

I tried to solve using apt --fix-broken install but it give me the error up above.

Ran into this issue trying to upgrade a machine from Debian 10 (buster) to 12 (bookworm) and found this thread on the Debian bug tracker.

The thread is tagged wontfix, but one of the participants posted a workaround which ended up working for me. Reproducing it here, but full credit to the original author:

cd /tmp
apt -y download libcrypt1
dpkg-deb -x libcrypt1_1%3a*.deb  .
cp -av lib/x86_64-linux-gnu/* /lib/x86_64-linux-gnu/
apt -y --fix-broken install

After running these commands, I was able to retry the apt upgrade && apt full-upgrade that had originally failed with your error, and was successful.
