Hi Tech support,

I am getting the error below when saving domain on Ubuntu 16.04. Please let me know how to resolve it. Thanks. Onesmus.

Hi Onesmus
There is a bug in some versions of perl

To fix.

copy $UMDIR/vn4.5/utils/perl/PrecisGeneral.pm to $UMDIR/vn4.5/utils/perl/PrecisGeneral.pm.backup
edit $UMDIR/vn4.5/utils/perl/PrecisGeneral.pm
and change all of instances of

m/(?<! \\) \${
to
m/(?<! \\) \$\{

where indicated by the error messages. There should be 4 instances.

If there are still issues you may need to change { to \{ and } to \} where indicated by the error message.

hopefully this will fix your problem.

The error is now as below,

Hi Onesmus
Are you getting this error when trying to save your domain as before or doing a different action?

Hi Saeed,

Yes, I am getting this error when saving domain.

Hi Onesmus

could you please check and see if the directory that the /home/ruirie/precis_expt/tmp/ directory exists and if so what are its content?

thanks,

Saeed

Hi Saeed,

The error "cp: cannot stat '/home/ruirie/precis_expt/tmp/new.gif': No such file or directory while executing" is NOW RESOLVED, but I can't explain how/why.

Here is what I did:
I imported the kenyan domain from the server into my laptop, loaded it into precis from regions folder, I was able to edit it and save. After which, I am able to define new domains and save.

The original error of m/(?<! \\) \${ was resolved by what you suggested, changing to m/(?<! \\) \$\{ or in short basically { to \{

Many thanks for the help.

Regards
Onesmus

Hi Onesmus,
glad to hear that the problem is sorted. I also saw your email with the screenshot attachment of the /tmp directory and looked alright, difficult to say what exactly could have caused it possible a temporarily system glitch!

Regards,

Saeed
