[18:36] Hey! I'm observing something really strange on my 21.04 install here. I had problems using fuse3 and came to this: [18:36] ~$ ls -la /usr/bin/fusermount [18:36] lrwxrwxrwx 1 root root 11 Feb 8 21:21 /usr/bin/fusermount -> fusermount3 [18:36] ~$ ls -la /usr/bin/fusermount3 [18:36] -rwsr-xr-x 1 2001 2501 39296 Feb 8 21:21 /usr/bin/fusermount3 [18:38] I usually don't touch any executables and I'm wondering how it comes that uid 2001 & gid 2501 is owning the binary. There is no user on the system (as you can see in the ls -la output) and it smells like intermediate ids of a worker in your build system. [18:38] I see the same thing happening to other executables, too. [18:40] I can imagine some debhelper scripts to be skipped or dpkg-buildpackage (or what ever else you use) not run with fakeroot.
