Is there a way to fix this error?

General system Pacman

Lately, when I run sudo pacman -Syu, I get this message.

(3/4) Checking which packages need to be rebuilt
parallel: This should not happen. You have found a bug. Please follow
https://www.gnu.org/software/parallel/man.html#reporting-bugs

Include this in the report:

  • The version number: 20221022
  • The bugid: Cannot read /root/.parallel/tmp/sshlogin/arkeo/linelen
  • The command line being run
  • The files being read (put the files on a webserver if they are big)

If you get the error on smaller/fewer files, please include those instead.

I understand that the error is caused by the /root/.parallel/tmp/sshlogin/arkeo/linelen which isn’t readable, although I can see it with sudo ls -als /root/.parallel/tmp/sshlogin/arkeo.

Is there a simple way to fix that error?

For example, if I edit that file to contain the console line length, would that be sufficient to avoid the error?
Is putting 134 sufficient to set the line length?

What is this GNU? :thinking: :laughing:

I know I can report the bug. I was wondering if a workaround could be as simple as editing a file. I know that wouldn’t fix the bug, but I wouldn’t see that error message, at least. :wink:

I’m not sure. Not familiar with this. :man_shrugging:

So you are using this for something?
It is a dependency for rebuild-detector.
And can be used in many ways… not sure for what you set it up?

I didn’t set it up. Actually, I thought that was an error every user who runs pacman -Syu would get.

When I install something from AUR, I don’t remove the build dependencies. Could that be a build dependency used from an AUR package?

I checked with yay -Qi parallel why it was installed.

yay -Qi rebuild-detector got me the following.

So, it was a dependency of rebuild-detector I installed without understanding it runs every time I update packages.

I removed it with yay -Rs rebuild-detector.

rebuild-detector
is installed per default … to give some info in case about packages that needs rebuilding:

it does not give any error here on several installs… so I was assuming you set something up…

I started getting that error three/four days ago; before, I was getting only a message about pacman which was checking which Perl modules had to be updated.

I haven’t installed anything new, these days. I just keep updating EOS with yay -Syu.

Your previous reply helped me to understand it’s not an error caused by pacman but by a tool that “hooks” into pacman. Without that tool, att least, I can run pacman -Syu or yay -Syu without seeing that message error.
I will reinstall rebuild-detector later.
