Curl: (43) A libcurl function was given a bad argument

Install, Configure and Update

Hi Katherine,

Thank you for the update.

I encountered an error while attempting to update CryoSPARC to version v4.7.0. The command and output are shown below:

$ cryosparcm update --version=v4.7.0
CryoSPARC current version v4.6.0
update starting on Tue Jun 3 21:27:03 EDT 2025

=============================
Updating to version v4.7.0.

Removing previous downloads…
Downloading master update…
curl: (43) A libcurl function was given a bad argument

Would you mind advising on how to resolve this issue? Thanks!

Best regards,
Shuhui

@Shuhui05 Please can you post the output of this command (run on your CryoSPARC master computer)

curl -v -L "https://get.cryosparc.com/download/master-v4.7.0/" > /dev/null

Hi Wtempel,

It return as below.

$ curl -v -L “https://get.cryosparc.com/download/master-v4.7.0/” > /dev/null
curl: (43) A libcurl function was given a bad argument

Thanks @Shuhui05 . What are the outputs of the commands

which curl
head -n 1 /etc/*release
ldd $(which curl)

?

Hi all,
thanks for sharing

I got a similar issue when trying to update the system.
At the command cryosparcm update (which worked since now) the output is:

CryoSPARC current version v4.7.1
          update starting on Fri Aug 29 14:41:58 CEST 2025

No version specified - updating to latest version.

And it stops. Apparently I also have the same curl issue (43).
I reinstalled several curl versions as sudo but nothing changed.

This is the output of the command

head -n 1 /etc/*release

==> /etc/centos-release <==
Rocky Linux release 8.10 (Green Obsidian)

==> /etc/os-release <==

Sorry, just realized that is seems updated to v4.7.1, although I’m not sure of this. I tried to manually update it by downloading the master and worker folders and update via --skip-download.
In any case would be nice to have the standard cryosparcm update back in function.

Welcome to the forum @Luigi.

On rocky-8.10, I expect that the /usr/bin/curl command included in the Rocky Linux “official” curl (-7.61.1 as of August 2025) package would do the job, and that
ldd /usr/bin/curl would mostly show libraries in the /lib64/ directory.
The ldd output you posted suggests that either

  • the /usr/bin/curl installation is broken on your system
  • or a different curl binary is being used. You may try the command
    cryosparcm call which curl
    to find out.
  • or your configured user environment is in an otherwise incompatible state. What are the outputs of the commands:
    env | grep PATH
cryosparcm call /usr/bin/env | grep PATH

thanks for the super fast reply @wtempel.

this is what I was suspecting.
here the outputs:

cryosparcm call which curl
/bin/curl

thanks for helping

Hmm. On rocky linux, I’d expect

# ls -l /bin
lrwxrwxrwx 1 root root 7 Oct 11  2021 /bin -> usr/bin

but I’d also expect /usr/bin/ to precede /bin/ in the $PATH.
If you are still wondering about how to fix the issue, please can you post the outputs of the commands

dnf whatprovides "*bin/curl"
sha256sum /usr/bin/curl
sha256sum /bin/curl
ls -l /bin/curl
env | grep PATH
cryosparcm call /usr/bin/env | grep PATH

Do you know with which commands /bin/curl was installed on your system?

Hi @wtempel,
after some checks I figured out that the cryosparc account has user specific environments and startup programs in a separate /.bashrc_profile. Now I modified it to have curl pointing to usr/local/bin. Curl itself seems to work, but when I launch cryosparcm update (with list or check) gives me empty answer as before. Bah.
i need to recall which command I used to have the error 43 but I think it’s still there.
Will keep you posted
