Answer 1

If you try to run an executable and you get the "no such file or directory" error, this often means that the executable is unable to find the correct dynamic loader. If you look at the output from the file command, you see:

...interpreter /lib64/ld-lsb-x86-64.so.3...

Does your system have /lib64/ld-lsb-x86-64.so.3? If not, that suggests that these binaries were built for a different architecture (e.g., 64 bit vs 32 bit) or for a different version of the C library (glibc).

Solutions include:

• Install packages that contain the necessary interpreter.

• Find a set of executables that have been compiled for the version of the C library installed on your system.

• Run things inside a Docker container or chroot environment that has the appropriate C library installed.

A hacky solution would be to use the patchelf command to change the interpreter path embedded in the binaries. Depending on your environment, that might work or it just may make everything crash.

Also, just symlinking from the .so.2 to .so.3 might work.
