Unmount does not work

[linuxissuper]

It seems SiriKali doesn't use a command for unmounting:

I'm on NixOS and built it myself (I probably forgot something?)
But I also tried a version installed through AUR on distrobox and there I get the same error
QIODevice::read (QProcess): device not open

Am I missing some option?

The unmounting command should look something like below

Command: "/usr/bin/fusermount" "-u" "/home/_/gocryptfs"
-------
Exit Code: 0
Exit Status: 0

StdOut:

StdError:
*************************************

In your case, SiriKali is failing to find "fusermount" executable

[linuxissuper]

ah I see, thanks

[linuxissuper]

This may be a stupid question, but is there a way of making SiriKali aware of the PATH variable?

[mhogomchungu]

Where is fusermount located in your system?

This commit should solve your issue.

Please update your sources from git version and try again.

/run/wrappers/bin/fusermount (it's all a little different on NixOS)
hm, I've updated and rebuilt but it still doesn't work

but this is probably nix problem
and I have to adjust my build config

[mhogomchungu]

This should now be solved by this commit and it now shows a descriptive error when fusermount can not be found.

I am not sure of a reason but there was one that made me intentionally not including the PATH variable when searching for executables.

I think a lot of people will encounter this problem, when their distro upgrade to a newer libfuse package.
This bug report libfuse/libfuse#794 (from May) says that fusermount is not provided anymore by libfuse and that fusermount3 is not entirely compatible.

For now, I did :
$ sudo ln -s /usr/bin/fusermount3 /opt/bin/fusermount
and so far it works.

I tried with gocryptfs version 2.4.0 and my observations are on unlocking, gocryptfs tries to use mount command and if that fails then it uses fusermount3 if available and falls back to fusermount.

I think the best solution here is for gocryptfs to handle unmounting of its volume because it knows how it mounted them. The best i can do is guess work and that is not nice.

In the mean time, i will try with fusermount3 if present and fall back to fusermount.

[mhogomchungu]

I have opened a feature request to ask gocryptfs to also handle unmounting.

Meanwhile, I deleted my symlink and I just installed package fuse2.
I wrongly assumed there was only 1 package, but in fact (at least with Archlinux) : there are 2 separate packages : fuse2 and fuse3.
