Arvados

arvados-client is linked against libfuse2. Its deb package requests fuse as a dependency, but in Ubuntu 24.04 fuse3 replaces fuse, so installing the package doesn't explicitly ask for libfuse2:

$ dpkg -l | grep fuse                                                                            15:23:21 [15/15]

When I run ldd against it, it shows the missing library:

$ ldd `which arvados-client`
        linux-vdso.so.1 (0x00007ffea75e8000)

If I ask to install libfuse2, the package libfuse2t64 gets installed and everything works as expected:

$ sudo apt install libfuse2
