[Bug 2127231] [NEW] /usr/bin/b3sum is a dangling symlink

[Keith Thompson]

Public bug reported:

A number of checksum commands are installed as symlinks in /usr/bin, 
pointing to the uutils command in ../lib/cargo/bin/coreutils .
 
uutils normally provides both "b2sum" and "b3sum" commands, but 
b3sum is missing in Ubuntu 25.10.

$ ls -l /usr/bin/b2sum /usr/bin/b3sum 
lrwxrwxrwx 1 root root 32 Sep 26 11:16 /usr/bin/b2sum -> ../lib/cargo/bin/coreutils/b2sum
lrwxrwxrwx 1 root root 32 Sep 26 11:16 /usr/bin/b3sum -> ../lib/cargo/bin/coreutils/b3sum
$ ls -lL /usr/bin/b2sum /usr/bin/b3sum 
ls: cannot access '/usr/bin/b3sum': No such file or directory
-rwxr-xr-x 115 root root 10828088 Sep 24 08:36 /usr/bin/b2sum
