Package: liblz4-1 Version: 0.0~r131-2 Severity: important Hello,
In a recent reboot, I found that my system got stuck at cryptsetup part (I have encrypted / and /usr), with an error message from /bin/ps saying that liblz4.so.1 is not found. It appears that /bin/ps is linked to liblz4, and is required early during booting, but liblz4 is installed in /usr/lib/x86_64-linux-gnu/liblz4.so.1.7.1 thus unavailable before /usr is mounted. $ aptitude why procps liblz4-1:amd64 i procps Depends libprocps6 i A libprocps6 Depends libsystemd0 (>= 209) i A libsystemd0 PreDepends liblz4-1 (>= 0.0~r113) After booting to recovery mode and copying /usr/lib/x86_64-linux-gnu/liblz4.so.1.7.1 to /lib/x86_64-linux-gnu/liblz4.so.1, the system boots normally again. Therefore, please considering install the library to /lib instead of /usr/lib.
