"fusermount3: mount failed: Operation not permitted"

[uohmak4fvpqe]

I have a fresh install of Clearlinux on my laptop (not in a container);
installed tup from brew; I also built it from master
both of them show this error upon running /path/to/tup:

[ tup ] [0.000s] Scanning filesystem...
[ tup ] [0.003s] Reading in new environment variables...
[ tup ] [0.003s] Parsing Tupfiles...
fusermount3: mount failed: Operation not permitted
tup error: Timed out waiting for the FUSE file-system to be ready.
tup error: Unable to mount FUSE on .tup/mnt

Running tup as root bypasses this error, but the build will fail anyway due to environment variables and stuff

[gittup]

Do other FUSE clients work on your system? For example, can you mount something with sshfs? What are the permissions on the fusermount3 binary?

[uohmak4fvpqe]

So, in my case it was somehow the libfuse package from brew messing with the platform-native fusermount3. Removing it got rid of the error entierly.

Unsure whether the problem is on brew side or on clearlinux side

[gittup]

Oh weird, I wouldn't have thought of that. I guess the two libfuses are different (incompatible) versions?

[uohmak4fvpqe]

I can tell that clearlinux has version 3.14.0 currently : https://github.com/clearlinux-pkgs/fuse/blob/main/versions

Not sure if this is normal though that brew packages take precedence on native ones even for native softwares, but it's been a pain since i've been using brew for natively missing packages. Hopefully one can always brew uninstall --ignore-dependencies things to force the use of native dependencies instead

Same story on Ubuntu 23.10
