Bug Description

Binary package hint: fuse-utils


This seems to be a regression. On Jan 30, using fuse-utils 2.7.2-1ubuntu2, everything works fine, I mount a remote system using sshfs and unmounting via fusermount -u mountpoint

On Jan 30 I installed the upgrade of fuseutils and libfuse2 to version 2.7.2-1ubuntu2.1

Since then, fusermount -u mountpoint fails with this error message:
"fusermount: failed to clone namespace: Operation not permitted"

I was not able to find this phrase anywhere in the net using google.

Downgrade to 2.7.2-1ubuntu2 fixes the problem.

I hope that this is not somehow connected to the fact, that my affected machine is a OpenVZ vserver (Strato Hosting in Germany). With this technique, by server does not have kernel and modules in the visible file system, so perhaps it's a mismatch between fuse-module and fuse-utils?

Oh wow, overwhelming response after about one month. "Long Term Support" means I need to wait for a long term until there is support?

Not even anybody stating "works for me", so I can go for blaming my hoster or his OpenVZ solution?

You would need the sys_admin capability on the container for it to work. This is what your hosting provider could execute to enable that capability:

vzctl set 194 --capability sys_admin:on --save
