[SOLVED] Unable to install curl

peter7089 · 01-18-2017, 05:47 AM

I am trying to install curl on Xubuntu. I run this command: apt-get install curl but i get missing dependencies:

Code:

root@osboxes:/home/osboxes# apt-get install curl
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
 curl : Depends: libcurl3 (= 7.35.0-1ubuntu2) but 7.35.0-1ubuntu2.5 is to be installed
E: Unable to correct problems, you have held broken packages.

But if i try to install the missing dependency libcurl3 it says that it is already the newest version:

Code:

root@osboxes:/home/osboxes# apt-get install libcurl3
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libcurl3 is already the newest version.
libcurl3 set to manually installed.
0 to upgrade, 0 to newly install, 0 to remove and 3 not to upgrade.

Did you update the APT database before trying to install?

Code:

apt-get update
apt-get install curl

Yes, i run apt-get update before trying to install curl.
I think the problem might be that i am trying to install curl on Xubuntu 14.04 which is older version, so i am not sure if i will be able to install libcurl3 package online.
Is it possible to install libcurl3 package manually? I found the download page for libcurl3 here: http://packages.ubuntu.com/trusty/libcurl3 which i think is the version for ubuntu 14.04 (trusty). But i am not sure which files i have to download. Do i have to download the files that are in 'Architecture' column?

Have you actually run:

apt update

apt upgrade

to check that all the programs you have installed from your repos are up-to-date?

You might find that apt upgrade produces some illuminating output.

apt-upgrade upgrades the Xubuntu version. What if i don't want to upgrade? Is it not possible to install curl without upgrading?

No it doesn't. apt upgrade (note, no hyphen) or apt-get upgrade updates your software packages to the latest ones in the repositories, after getting your confirmation that you want to proceed.

apt update (or apt-get update), despite the name, updates no packages. It merely looks at the repositories to update the system's knowledge of which of your installed packages are updateable dependent on the version numbers.

Ok, i run apt-get upgrade but i am still not able to install curl. Getting the same dependencies error.

I run also apt upgrade but no change.

There is no need for you to run both apt-get upgrade and apt upgrade - they are for all intents and purposes the same command, it's just that the latter uses the more modern apt command.

Just so we can be happy that everything is nice and up to date, please enter:

apt update

apt upgrade

and paste the output from both commands here.

I finally fixed it. I used aptitude to try to install curl and it asked me to downgrade the libcurl3 package, i choose 'yes' and it installed curl. Solving dependencies issues in linux is such a pain!
