[Solved] Cannot write file "/home/rpowell/.config/FreeFileSync/Install.dat.eace.tmp".

Posts: 10 · RogerP 21 Apr 2022, 18:12

I know this has been asked before, and I've read all the posts.

FFS simply doesn't even start, I get the above message along with `EACCES: Permission denied [open]`. Same with RTS.

I've had this problem since FFS v11.16; I have just installed 11.20 (I've been using FFS regularly for at least 8-9 years).

I use Endeavorous Linux (type of Arch Linux)

NAME="Arch Linux"

PRETTY_NAME="Arch Linux"

ID=arch

BUILD_ID=rolling

ANSI_COLOR="38;2;23;147;209"

HOME_URL="https://archlinux.org/"

DOCUMENTATION_URL="https://wiki.archlinux.org/"

SUPPORT_URL="https://bbs.archlinux.org/"

BUG_REPORT_URL="https://bugs.archlinux.org/"

LOGO=archlinux-logo

I have tried all possible permission settings in the folder. The file `Install.dat.eace.tmp` doesn't exist so it's not locked. I've tried creating an empty file with that name and giving permissions.

Any ideas?

You've started with a great step, of course. I'm guessing Arch Linux/Endeavorous doesn't use SELinux or AppArmor?
Have you checked that the application is running as the correct user? (No reason to think it isn't, but I don't have a lot.)
Are you comfortable running the application with strace, and grepping the output for /open\(/?
edit 1: I'm starting to look through the changes between 11.15 and 11.16. In the mean time, what kind of filesystem is ~/.config/FreeFileSync/ on?

The failing code is in zen/file_io.cpp (shortened)

const int fdFile = ::open(filePath, O_CREAT | O_EXCL | O_WRONLY  | O_CLOEXEC,

    S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH | S_IWOTH); //0666 

 if (fdFile == -1)

 {

 }

One trigger could be the O_EXCL, another the 0666.

Does this mean you've been unable to run any FFS version since 11.16?

What do you get for the following command:

strace touch "/home/rpowell/.config/FreeFileSync/Install.dat.123.tmp"

Looks like there is a general permission issue when accessing this folder, not just with FFS:

openat(AT_FDCWD, "/home/rpowell/.config/FreeFileSync/Install.dat.6e95.tmp", O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK, 0666) = -1 EACCES (Permission denied)

Can you indulge us with examining this directory in more details? Be prepared to scrub out any personal data, although I don't expect the filenames inside directory ~/.config/FreeFileSync should be a problem.

ls -alZ ~/.config/FreeFileSync

id

ls -aln ~/.config/FreeFileSync

The first one shows us the permissions (from the -l, long) including selinux context (-Z) and includes the directory itself (-a) which shows up as dot "." in the listing. The "id" command shows us your username and uid. The third command tells ls to show us uid and gid of the owners of the files. It is possible you copied this directory from another system and the uid is not the same.
Or perhaps this directory is mounted on a read-only filesystem (highly unlikely; and the error message usually makes that clear).

/home/bgstack15$ mount | grep "on $( df -PBM . | tail -n1 | awk '{print $NF}' ) type"

/dev/mapper/fedora_vm2-home on /home type ext4 (rw,noatime,seclabel)

Here is my output for a command that shows us the that my current directory is underneath mount point /home and it is mounted read-write (rw).

Let me jump the gun and say that if the uid/username of the owner of ~/.config/FreeFileSync is not your current uid/username, then you will need to chown it.

sudo chown --recursive ~/.config/FreeFileSync

Hm, the permissions clearly look good. I'm at a loss.

Can you show us the output of:

df -BM ~/.config/FreeFileSync

df -i ~/.config/FreeFileSync

mount | grep "on $( df -PBM . | tail -n1 | awk '{print $NF}' ) type"

It makes no sense that this one directory is unwriteable for your user. Perhaps you could try:

sudo touch /home/rpowell/.config/FreeFileSync/Install.dat.987.temp

The requested output:

[rpowell@roger-pc ~]$ df -BM ~/.config/FreeFileSync

/dev/sda1        928925M 184842M   696825M  21% /

[rpowell@roger-pc ~]$ mount | grep "on $( df -PBM . | tail -n1 | awk '{print $NF}' ) type"

/dev/sda1 on / type ext4 (rw,noatime)

And I already tried touching a new file. But when I do, FFS seems to try a new name and then doesn't have the permission to create it. I will try checking the Endeavouros forum.

??? According to your log (viewtopic.php?t=9309#p33765), touch fails, unrelated to FFS.

You are right. Sorry for being stupid. When FreeFileSync 11.20 Setup runs it assumes the username and the name of the home directory are the same. For reasons of ease of mounting a remote drive I changed the name of the home directory. E.g.:

[rpowell@roger-pc ~]$ pwd

/home/rogerp

Maybe I should install from

FreeFileSync_11.20_[Donation_Edition]_Linux.zip

instead. I'll give that a try. Sorry for being a time waster.

Apologies again! The zip file just contains the binaries, I thought for a minute it might be source.

Let me jump the gun and say that if the uid/username of the owner of ~/.config/FreeFileSync is not your current uid/username, then you will need to chown it.
sudo chown --recursive ~/.config/FreeFileSync

Thank you!

Now there's something for FFS to improve!

FFS should first consider the HOME environment variable, then fall back to getpwuid(getuid())->pw_dir. This is default Linux behavior and should solve your requirement, too: https://www.mediafire.com/file/qi2jdd4t0ouj676/FreeFileSync_11.22_beta_Linux.tar.gz
