A whole pile of my applications are no longer launching (xchat, vmware, etc) with this error.

xchat: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory

I did some searching and tried a few of the posts found (on this site and others) but I can't seem to get past this. I checked in /usr/lib/x86_64-linux_gnu -- assuming that is where it wants to find the file -- and sure enough there is no entry. I'm just not sure how to put it there.

Can someone help?

  • Is this a 64 bit system? Are the programs having problems 64 bit? – ubfan1 Sep 11 '15 at 22:10
  • Yes on both fronts. All these programs were working -- clearly I did something I wasn't supposed to. I was trying to get netExtender for a WebVPN working a few days back. Something I did then must have caused this. – jardineworks Sep 12 '15 at 12:05

Reinstall the package libssl1.0.0

sudo apt-get install libssl1.0.0:amd64

The 64 bit shared library should be at

/lib/x86_64-linux-gnu/libssl.so.1.0.0

with a link to it at

/usr/lib/x86_64-linux-gnu/libssl.so

The static library is at

/usr/lib/x86_64-linux-gnu/libssl.a

If it's just the links missing, you can replace them yourself without doing a package reinstall.

Looks like the file was deleted (or moved --see if locate libssl.so.1 finds it). Of course, the package manager would know nothing about that, so try the -f force on the install, and if that fails, try the apt-get --reinstall switch.

  • Hi ubfan, ... I ran the package installer command and the feedback I got was that libssl1.0.0 was already at the newest version. I checked /lib/x86_64-linux-gnu/libssl.so.1.0.0 and the file was not there, however the other two you referenced we're there. In fact the second one showed up as lrwxrwxrwx 1 root root 37 Jun 11 11:32 libssl.so -> /lib/x86_64-linux-gnu/libssl.so.1.0.0 .. but the fact that the file it is linking to is not there I suppose is the issue. Can I force it to install even it "it is already there"? (OS seems to be confused) – jardineworks Sep 14 '15 at 11:44
  • The --reinstall flag did the trick. I didn't even know that was an option. Thanks so much ubfan1 – jardineworks Sep 14 '15 at 20:55
  • Where should I get libssl1.0.0from? It's not in my sources and the only other option i get is libssl3. – Kyo Kazuto Apr 21 '23 at 14:10

  • I experienced a similar problem setting up a new system (Ubuntu 22.04.2 LTS, openssl 3.0.2-0ubuntu1.8). and successfully applied ubfan1's solution. Is the lack of a symlink a bug in the openssl (or some other) package? – NanoBotic Apr 23 '23 at 18:11
  • @nanobotic You should ask your own question. This answer predates the combination of /lib and /usr/lib, so doesn't fully apply to current releases. – ubfan1 Apr 23 '23 at 23:33
