Recently, for no reason, my clamav service stopped working. So I've uninstalled it with

yum install clamav

and now when I try to install it again it complains with:

...
--> Finished Dependency Resolution
Error: Package: clamav-update-0.103.11-1.el7.x86_64 (epel)
           Requires: libcurl.so.4()(64bit)
Error: Package: clamav-0.103.11-1.el7.x86_64 (epel)
           Requires: libcurl.so.4()(64bit)
 You could try using --skip-broken to work around the problem
 ...

How can this be solved? Can it be installed from sources into /usr/local instead using the system's one?

You can try executing these commands:

ldd -r /usr/lib64/libcurl.so.4
rm /usr/local/lib/libssh2.so.1

 

If upper solution doesn't solve this try to install/reinstall libcul and libcurl-devel package

yum install libcurl libcurl-devel
yum reinstall libcurl libcurl-devel

This gives the following:

ldd: /usr/lib64/libcurl.so.4: No such file or directory

These commands gives this in Centos 7:

No package libcurl available.
No package libcurl-devel available.
Error: Nothing to do

 

I should add, for the record, that I was using the cityfan repo (http://www.city-fan.org) to keep Curl updated. Recently this repo stopped working and I have had to remove it. But it leaved the problem previously metioned here.

First command returns nothing

The second one the same, nothing.

The third one's output:

        libcurl.so.4 (libc6,x86-64) => /usr/local/lib/libcurl.so.4

try this 

ln -s /usr/local/lib/libcurl.so.4 /usr/lib64/libcurl.so.4

and install clamd again

Same problem again. 

I've cleared also caches with

yum clean all

and then tried

yum install clamav

Error:

Error: Package: clamav-update-0.103.11-1.el7.x86_64 (epel)
           Requires: libcurl.so.4()(64bit)

can you provide this command output : 

ls -la /usr/lib64/ | grep libcurl

It gives me this:

lrwxrwxrwx   1 root root       27 Nov 26 23:46 libcurl.so.4 -> /usr/local/lib/libcurl.so.4

 

try this : 

rm -rf /lib64/libcurl.so.4
ln -s /usr/local/lib/libcurl.so /usr/lib64/libcurl.so.4
ln -s /usr/local/lib/libcurl.so /usr/lib64/libcurl.so

if this not works i think you need to use old version of curl 7.xx

also try

yum install clamav --skip-broken

also you can install latest clamav via this command : 
 

rpm -ivh https://www.clamav.net/downloads/production/clamav-1.0.4.linux.x86_64.rpm

Now tried

yum install clamd

and same error

This way there is no complains

rpm -ivh https://www.clamav.net/downloads/production/clamav-1.0.4.linux.x86_64.rpm

But now. How can I setup clamav? (service and so on)

systemctl start clamd

systemctl start clamd

systemctl status clamd

Remove the clamav

rpm -e --nodeps clamav 

and install via yum  :

yum install clamav --skip-broken

it gives:

Then you need to install base version of curl from centos 7 seems latest curl is not supported by old clamav.

Remove this lines "exclude=curl* libcurl*" from /etc/yum.conf

And install curl

yum install curl libcurl libcurl-devel

Now I was able to install it and also amavis. Problem is that now clamd service reports error status. Can't start it

Thanks a lot for all the tips. Finally I got it working after dealing with the clamd service. Initially there was a problem with a very high CPU usage, but fortunately I solved it with:

 sh /scripts/clamd_fix_100_cpu_usage

Now it seems that all goes fine. Fingers crossed 🙂
