1. Logion as user
2. > zellij
3. Error occurred: PermissionDenied

I installed zellij via cargo install --root /opt zellij. It works using root and doas zellij, but as soon as I try to use it without root permissions, it just fails. The error message can be improved by telling me which permissions are missing (e.g. which file? it tries to access). As it stands, I'd have to start debugging this application to get it working, which is unfortunate.

The debug option doesn't help and the log is empty. Here's a screenshot for your convenience:

The user's shell is nushell with starship prompt. I'm SSH'd onto a Proxmox VM - which I want to turn into my main PC as soon as it's configured and escape the claws of the Windozer :)

Looking at the screenshot on the right you posted, it seems that zellij is currently running under the user maru.

If you installed zellij as root, you need root privileges to run zellij.

Does this user have root privileges?

I would take zellij compiled version and stick it somewhere in the path --root seems to be the issue.

/opt is in the path. How is --root the issue?

Yes. The user does not have root rights, that would defeat the purpose of having a separate user from "root" ;)

Zellij was installed as root (like all other packages), but into a public directory (see --root /opt argument)

[qballer]

chmod +x ?

[minecrawler]

Now here's the thing:

so my guess is that Zellij tries to access some other location which my user does not have access to..

I'm having the same issue I've even copied zellij to ~/.local/bin but it didn't work.

• zellig --help work
• zellij -c <path to cinfig.kdl> does NOT work (PermissionDenied)

I suppose indeed it tries to access some file or some system resource?

EDIT: worked again after a system restart. Could it be that there was some process not closed and locking on some resource?

Had a similiar issue running zellij in WSL. Running with strace revealed that I had incorrect permissions for the folder /run/user/1001:

$ strace zellij
execve("/usr/local/bin/zellij", ["zellij"], 0x7ffdc5276fa0 /* 31 vars */) = 0
mmap(NULL, 1856, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fce45624000
arch_prctl(ARCH_SET_FS, 0x7fce45624660) = 0
set_tid_address(0x7fce457a94b8)         = 1056
[...]
getrandom(NULL, 0, GRND_NONBLOCK)       = 0
getrandom("\xd6\xbd\x1f\x29\x54\xa5\x69\x9d\xa7\x82\x05\xe9\x2d\x3b\x60\x65\x69\x77\x51\xff\x03\x48\x5f\xea\xc0\xa9\xc1\xcc\x7b\x69\x58\x4e", 32, 0) = 32

write(2, "Error occurred: ", 16Error occurred: )        = 16
write(2, "PermissionDenied", 16PermissionDenied)        = 16
write(2, "\n", 1
)                       = 1
sigaltstack({ss_sp=NULL, ss_flags=SS_DISABLE, ss_size=8192}, NULL) = 0
munmap(0x7fce45621000, 12288)           = 0
exit_group(1)                           = ?
+++ exited with 1 +++

Fixing the permission that it looks like so fixed the issue:

/run/user$ ls -lsah
total 0
0 drwxr-xr-x  3 root             root              60 May 29 16:51 .

0 drwx------  4 thg              thg              120 May 29 16:51 1001

I didn't know about strace, but that's a really good tool, thank you! I found the same entry:

openat(AT_FDCWD, "/run/user/0/zellij/0.36.0", O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = -1 EACCES (Permission denied)

However I'm not comfortable with Zellij trying to access my root's folder

I still have an open session with stuff to do, but I'll try to re-install Zellij with with regular user and hope the problem will be solved by that (for now). ALl in all, this sounds like a bug in ZelliJ, probably trying to access the folder of the user who installed the program. On Linux, that's not a good practice, since Linux is a multi-user system with at least root and a regular user being daily drivers.

Yeah, I'm running into a similar oddity. But under certain environment variables combination ( i.e. doing an su with or without the - before the username to switch to, it seems to use a totally different directory for the sockets.

In one case it even uses the /tmp dir: /tmp/zellij-1003/0.38.2.

I haven't found a way to configure which dir it uses, though.

[zicklag]

Ah, I figured out:

export ZELLIJ_SOCKET_DIR=/run/user/[userid]/zellij

I'm not sure how it determines the default value, but just set that dir to one appropriate for your user in your .profile or whatever, and you should be good.

PS: Strace is awesome, thanks for pointing that out!

This is just a status report, but I hope it helps someone!

I had get error message after write this to ~/.bashrc.

export ZELLIJ_SOCKET_DIR="/run/user/$USER/zellij"

More precisely,

1. Start zellij
2. Behavior similar to clear occurs
3. It looks like just a normal shell
4. Try sudo zellij
5. I can do sudo zellij normally.
6. exit
7. Previous zellij error appears
8. Try sudo zellij
9. I can do sudo zellij normally.
10. exit
11. Nothing happens. usually.
