I try to test the new full-disk backup feature but I cannot get it working. When I go to Full Disk Source, I see the drive sda (1,819 TB) but when I try to see the partitions an error window appears with: ```plaintext Failed to initialize disk: /dev/sda, Failed to initialize disk: Unable to load shared library 'libc_wrapper.so' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable: /usr/lib/duplicati/libc_wrapper.so: cannot open shared object file: No such file or directory /usr/lib/duplicati/liblibc_wrapper.so: cannot open shared object file: No such file or directory /usr/lib/duplicati/libc_wrapper.so.so: cannot open shared object file: No such file or directory /usr/lib/duplicati/liblibc_wrapper.so.so: cannot open shared object file: No such file or directory ``` ---

Do you see the file `/usr/lib/duplicati/libc_wrapper.so` on your system? What is the OS/CPU-arch you are running and what version/package of Duplicati are you using? If the file is missing and you want a quick-fix, you can download the matching file from here: > **[duplicati/proprietary/DiskImage/NativeLibraryWrappers at master ยท...](https://github.com/duplicati/duplicati/tree/master/proprietary/DiskImage/NativeLibraryWrappers)** > > master/proprietary/DiskImage/NativeLibraryWrappers ---

What I find on my system is: ```plaintext /usr/lib/duplicati/runtimes/linux-x64/native/libc_wrapper.so /usr/lib/duplicati/runtimes/linux-arm64/native/libc_wrapper.so /usr/lib/duplicati/runtimes/linux-x86/native/libc_wrapper.so /usr/lib/duplicati/runtimes/linux-arm/native/libc_wrapper.so ``` but not: /usr/lib/duplicati/libc\_wrapper.so I have a raspi5 with NextcloudPi v1.58.0 running and updated duplicati with: ```plaintext apt install ./duplicati-2.4.0.0_stable_2026-09-03-linux-arm64-gui.deb ``` The OS is Debian Trixie ---

The packaging does not put the `libc_wrapper.so` into the correct location so it fails to load. Additionally, we should not ship libraries that are not relevant to the package. > [@waki](#): > > I have a raspi5 In that case, you have the arm64 version, so try this command: ```plaintext sudo ln -s /usr/lib/duplicati/runtimes/linux-arm64/native/libc_wrapper.so /usr/lib/duplicati/libc_wrapper.so ``` That should put the library in the right place so Duplicati can load it. ---

Thank you. That did the trick. Will there be a new package? ---

> [@waki](#): > > Will there be a new package? Yes. The canary build has the fix: [https://duplicati.com/download?channel=canary](https://duplicati.com/download?channel=canary) If you have the option to try it out and report back, that would be much appreciated. Otherwise, the fix will be included in the next stable patch release (2.4.0.1).
