Resolved Plesk 18.0.27 Installation Problem, Possibly bug

[DaveMurray]

Hello Plesk Team and all Pleskians out there.
Many days now we are trying to install the latest plesk release and always we are hiting in that error :

Traceback (most recent call last):
File "/usr/local/psa/bin/yum_install", line 264, in <module>
main()
File "/usr/local/psa/bin/yum_install", line 250, in main
inst, rem = installer.resolve(to_install, opts.remove, opts.tries)
File "/usr/local/psa/bin/yum_install", line 172, in resolve
raise Exception("Failed to solve dependencies:\n" + '\n'.join(msgs))
Exception: Failed to solve dependencies:
plesk-php74-mbstring-7.4.6-1centos.7.200514.1743.x86_64 requires libonig.so.2()(64bit)
Error: The Yum utility failed to install the required packages.

the fact is that we have already install oniguruma and oniguruma-devel packages but that error, again and again appears.
We try many things to try solve it without success. The host os is: CentOS 7.8 at AX41 Hetzner server
We cannot start as you can see our business and we loosing needed time.

That post is a kind of bug report, and we hope help us to find a solution

Thank you plesk team for your hard and professional work, and thanks in advance for any provided help to this issue

Make sure that you have the same output of following commands:


# rpm -qa | grep onig
oniguruma-5.9.5-3.el7.x86_64

# ll /usr/lib64/libonig.so.2
lrwxrwxrwx 1 root root 16 Jun 3 04:49 /usr/lib64/libonig.so.2 -> libonig.so.2.0.0

[root@core ~]# rpm -qa | grep onig
oniguruma-6.8.2-1.el7.x86_64
oniguruma-devel-6.8.2-1.el7.x86_64
[root@core ~]# ll /usr/lib64/libonig.so.2
ls: cannot access /usr/lib64/libonig.so.2: No such file or directory
[root@core ~]# ll /usr/lib64/libonig.so
libonig.so libonig.so.5 libonig.so.5.0.0

I assuming that a manual symbolic link will make it like your output
am i have right?

oniguruma installed from epel

oniguruma installed from epel

Bad idea to use third-party repos on Plesk server.

You could try at least.

i downgrade to oniguruma-5.9.5-3.el7.x86_64 (stable epel, not epel testing) and is fixed, So the learning lesson for me and for anyone is NOT to have any 3rd party repo for any reason in the installation of plesk or while using/operate plesk. Better and safer is the --enable-repo=somerepo if you need to install something special

thanks Igor, you give me the hint for what to search! -- its solved
