Error: too short control message length

[viluon]

I'm getting Error: too short control message length (no other output, exit code 1) when trying to mount a large 7-Zip archive. A quick GitHub search suggests the error comes from polyfuse. I installed archivefs with cargo install, so RUST_BACKTRACE=1 doesn't do anything.

Sadly, I cannot share the archive in question, but I can share some metadata. I will try to come up with an MRE and a backtrace later.

Type = 7z
Physical Size = 2785371007
Headers Size = 68985
Method = LZMA2:26 BCJ
Solid = +
Blocks = 13

Yep, it comes from plyfuse, so please file a bug there.

I had this issue too. Apparently fuse3 provide fusermount3 instead of fusermount.
Installing fuse2 fixed this.
