Created attachment 186731 [details]
The only window i can have.

Plasma Vault isn't working for me. I get a window that doesn't let me choose the encryption method. The application only asks me to enter a directory name, which I do, but the 'next' button remains grayed out and I can't proceed.

My PATH includes gocryptfs, crypfs, and encfs. 
I compiled plasma-vault with the following cmake command:

      cmake -D CMAKE_INSTALL_PREFIX=$KF6_PREFIX \
            -D CMAKE_INSTALL_LIBEXECDIR=libexec \
            -D CMAKE_BUILD_TYPE=Release         \
            -D BUILD_QT5=OFF                    \
            -D BUILD_TESTING=OFF                \
            -W no-dev ..
            
and get :

Thanks for the bug report. I'm not able to reproduce this on Fedora 43 with Plasma 6.5.2 (before updates)
Can you try again with Plasma 6.5.3, using the Nobara package?

If you're building this yourself, then you probably need to fix how you're building it. In that case, you'll need to contact Nobara for assistance.
Comment 2 Alain 2025-11-26 12:35:55 UTC 
plasma-vaullt-6.5.3 doesn't work too. I have :
encfs version 1.9.5
CryFS Version 1.0.1
gocryptfs [unknown]; go-fuse v2.8.0; 2025-11-11 go1.23.2 linux/amd64
All of them are working fine in command line.
Comment 3 Alain 2025-11-26 14:16:55 UTC 
On my system, the `gocryptfs` command returned:
`gocryptfs [Unknown]; go-fuse v2.8.0; 2025-11-12 go1.23.2 linux/amd64`
                     ^^^^^^^
Plasma-vault doesn't like this 'unknown' version. After patching and recompiling `gocryptfs-2.6.1`, I now get:
`gocryptfs [2.6.1]; go-fuse v2.8.0; 2025-11-26 go1.23.2 linux/amd64`

Plasma-vault now works correctly with `gocryptfs`, but I still don't have the option to choose 'encfs' or 'cryfs'.

According to the source files `cryfsbackend.cpp` and `encfsbackend.cpp`, my versions of 'cryfs' and 'encfs' are correct. 
CryFS Version 1.0.1
encfs version 1.9.5
fusermount version: 2.9.9

Any ideas?

cryfs and encfs are no longer supported for new vaults
Comment 5 TraceyC 2025-11-26 17:02:21 UTC 
At this point, it sounds like plasma-vault is working as expected with gocryptfs. Are you having any other issues with it, Alain?

No more issue now. It works as expected. Thank you.
