Yes, this is a known bug on the Apache Java VFS libraries.
We have solved it in the interface by sanitizing the names when possible, but this is not always under control.
Here was the issue:
[root@xxx ~]# find /var/lib/nethserver/webtop/domains/NethServer/com.sonicle.webtop.vfs/mydocuments// -name ':’
find: ‘/var/lib/nethserver/webtop/domains/NethServer/com.sonicle.webtop.vfs/mydocuments//’: No such file or directory
[root@xxx ~]#
[root@xxx ~]# find /var/lib/nethserver/webtop/domains/NethServer/com.sonicle.webtop.vfs/mydocuments// -name ':’
find: ‘/var/lib/nethserver/webtop/domains/NethServer/com.sonicle.webtop.vfs/mydocuments//’: No such file or directory
[root@xxx ~]#
Now it’s also impossible to get access with the WebTop Admin.
There is a file named C: into admin /var/lib/nethserver/webtop/domains/NethServer/com.sonicle.webtop.vfs/mydocuments/admin folder.
You can rename it (if complete name is C: and you don’t have truncated result) launching command mv /var/lib/nethserver/webtop/domains/NethServer/com.sonicle.webtop.vfs/mydocuments/admin/C: /var/lib/nethserver/webtop/domains/NethServer/com.sonicle.webtop.vfs/mydocuments/admin/C.bak
