curl: symbol lookup error: curl: undefined symbol: curl_url_cleanup

I'm facing this issue in my Ubuntu 20.04.2 LTS (fossa-charmander-14 X60). I've bought new DELL Latitude 5420. When I type the command "curl" this error shows up.

curl: symbol lookup error: curl: undefined symbol: curl_url_cleanup

parveen@eagle:~$ sudo apt install curl
[sudo] password for parveen:

curl is already the newest version (7.68.0-1ubuntu2.7).
0 upgraded, 0 newly installed, 0 to remove and 16 not upgraded.

It says I already have curl, but I think it's not properly linked. When I type "man curl" it shows all manual docs about curl. But it's not working, please help me guys.

here's my answer:

1- first remove current curl package

sudo apt purge curl

2- install curl using snap

sudo snap install curl

3- remove any older curl files

sudo rm -rf /usr/local/bin/curl*

4- link snap curl

type curl
#curl is hashed (/snap/bin/curl)
hash -d curl

On Alpine it is just needed to run apk upgrade before the install.

I'm using Ubuntu 20.04.2, Dell Latitude 3410. I was getting the following error.

~> curl
curl: symbol lookup error: curl: undefined symbol: curl_url_set, version CURL_OPENSSL_4

I reinstalled curl with snap and it solved my problem.

~> sudo apt remove curl
~> sudo snap install curl

I also had a curl image with docker if necessary.

~> docker run curlimages/curl google.com

I found a different solution for this problem. I did the following:

1st - find out where was the dependency of curl to libcurl. For some reason there is an issue with this link.

sudo ldd $(which curl) | grep libcurl

The output pointed to a link at the following location:

/usr/local/lib/libcurl.so.4

Then I used the command:

sudo apt-get purge curl

After purging curl, I checked to see if that file was there, and it was there indeed. So I did the following:

sudo rm /usr/local/lib/libcurl.so.4 (or the path that you got previously)

And than I reinstalled curl with the following commando:

sudo apt-get install curl

And everything started working afterwards!!!

Note: Problem returns after installing certain packages

After installing other packages the problem came back and I had to repeat the process. So it is not a very stable solution. Apparently the file that I deleted was created back again. I am still looking for a permanent solution.

I found a solution. First I used this command sudo rm -rf /usr/local/bin/curl* to remove curl from this location. Then if I type curl it shows me the error bash: /usr/local/bin/curl: No such file or directory. Then I used type curl which gave me the output curl is hashed (/snap/bin/curl). Then I used hash -d curl, after this my curl started working.

Comments from this answer really helped.
