ld-linux-x86-64.so.2 links to a non-existent file

[Leo Arias]

In snapd, the file /snap/core/current/lib64/ld-linux-x86-64.so.2 is a link to /lib/x86_64-linux-gnu/ld-2.23.so, which doesn't exist.

$ ls -lah /snap/core/current/lib64/
totalo 0
lrwxrwxrwx 1 root root 32 Nov 16 16:50 ld-linux-x86-64.so.2 -> /lib/x86_64-linux-gnu/ld-2.23.so

$ ls /lib/x86_64-linux-gnu/ld-2.23.so
ls: ne eblas atingi '/lib/x86_64-linux-gnu/ld-2.23.so': Dosiero aŭ dosierujo ne ekzistas

$ ls /lib/x86_64-linux-gnu/ld-2.24.so
/lib/x86_64-linux-gnu/ld-2.24.so

It seems that the link has to be updated to point to 2.24.

This affects snapcraft, which uses this library when building classic snaps.

This problem was introduced by PR #1170 where the check for existence (and returning) happens before resolving the link into the core snap.

For what it is worth, I think the underlying bug here is in the core snap itself (the dynamic linker symlink should be relative). I've filed that separately as bug 1684063.
