That’s… tricky. >mount: failed to read mtab: No such file or directory This might be a container issue. >mount: /proc: mount(2) system call failed: Too many levels of symbolic links. Check if /proc outside of pbuilder but inside the container is right. There also might be a /dev/shm vs. /run/shm issue.
