"[init] database is locked" when starting app

[kurja]

that returns a bunch of of permission denied notifications, running with sudo returns absolutely nothing for both /tmp and /var

Another thought, is this on a NFS-mount ... or directly from the local machine ?

local.

hi
ok let's try "strace".
open a terminal and run: strace -f -o bla.txt -e trace=open,fcntl,stat name_how_you_start_your_database
post the output of bla or have a look by yourself at the file. it is plain ascii. you have to look for the fcntl systemcall - looks like
fcntl(3, F_SETLK, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}) = 0
go back in the trace until you find the open-call with the file-descriptor (here 3)
the open-call looks like: open("blu", O_RDWR) = 3
and you can see that the process want to lock "blu". this should be the lockfile.
move this file "blu" to _blu and try to start your database again.
good luck
ciao

Could try looking at your hidden config files in your home directory.
Possibly a .lock file that wasn't released due to the crash.
Maybe delete ~/.config/darktable if it exists.

output of that strace command is the very same database locked- message

in bla.txt, I found ".config/darktable/library.db", O_RDWR|O_CREAT|O_LARGEFILE, 0644) = 4"

I renamed the file, and now darktable starts!! Apparently the database contained just thumbnail images.

Thank you all!
