Solve the problem of Error-Perl execution failed prompt during webmin upgrade.

When you upgrade webmin, the following message is displayed:

Error-Perl execution failed
Undefined subroutine & WebminCore: translate_filename
Called at/usr/libexec/webmin/web-lib-funcs.pl line 14.

At this time, we can log on via ssh, root

Yum-y upgrade webmin

Then re-access the webmin background to see if it is normal
However, when you perform the upgrade, the following message is displayed:

TypeError: unsubscriptable object

You may need to execute

Yum clean metadata // This statement can be executed normally. If this statement cannot solve the problem, continue with the following operations:
Yum clean dbcache
Yum makecache

Then execute

Yum-y upgrade webmin

After executing the clear command, I upgraded webmin.
