Having fun while upgrading Debian 10 to 11.
The Problem
The following error is thrown during a Debian upgrade from Buster to Bullseye:
/usr/bin/python3: error while loading shared libraries: libcrypt.so.1: cannot open shared object file: No such file or directory
The file /lib/x86_64-linux-gnu/libcrypt.so.1
used to be in package libc6
on Stretch and Buster until it was split off into a separate libcrypt in Bullseye (and in Sid).
When upgrading libc6
the system ends in a situation where libcrypt.so.1
is removed before a replacement from a new package is installed.
The Workaround
This is the repo file /etc/apt/sources.list
:
deb [arch=amd64] http://ftp.uk.debian.org/debian/ bullseye main contrib non-free deb-src http://ftp.uk.debian.org/debian/ bullseye main contrib non-free deb [arch=amd64] http://security.debian.org/debian-security bullseye-security main contrib non-free deb-src http://security.debian.org/debian-security bullseye-security main contrib non-free deb [arch=amd64] http://ftp.uk.debian.org/debian/ bullseye-updates main contrib non-free deb-src http://ftp.uk.debian.org/debian/ bullseye-updates main contrib non-free deb [arch=amd64] http://deb.debian.org/debian bullseye-backports main contrib non-free deb-src http://deb.debian.org/debian bullseye-backports main contrib non-free
And these are the steps that I used to resolve the problem:
$ cd /tmp $ apt download libcrypt1 $ dpkg-deb -x libcrypt1_1%3a4.4.33-2_amd64.deb . $ sudo cp -av lib/x86_64-linux-gnu/* /lib/x86_64-linux-gnu/ $ sudo apt --fix-broken install

This finally fixed my issues with upgrading buster. Thanks a lot!
No worries, you’re welcome!
Me too. Fixed my install as well. Many Thanks!
Thanks! This worked going from Buster to Bookworm too
You’re welcome!
