I made a full upgrade from Ubuntu v18 to Ubuntu v20.

Shutter was not upgraded - it was removed.
I was trying to install from CRAN or from source.
Both complain about old Perl libraries.

When I am trying to compile from source and run it, this is the message I get...
I read somewhere that I can have two Perl installations in my system. However, I do not know if the problem is of that kind - does it require for an older version of Perl or is it a problem of paths?

Using find / search I cannot locate the file "always.pm" (after some minutes, I break it).

Can't locate Carp/Always.pm in @INC (you may need to install the Carp::Always module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.30.0 /usr/local/share/perl/5.30.0 /usr/lib/x86_64-linux-gnu/perl5/5.30 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.30 /usr/share/perl/5.30 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at /usr/local/bin/shutter line 39.

    (F) You said to do (or require, or use) a file that couldn't be found.

    Perl looks for the file in all the locations mentioned in @INC, unless

    the file name included the full path to the file.  Perhaps you need

    to set the PERL5LIB or PERL5OPT environment variable to say where the

    extra library is, or maybe the script needs to add the library name

    to @INC.  Or maybe you just misspelled the name of the file.  See

    "require" in perlfunc and lib.

NOTE: Hugin is compiled from source with manual flags that I needed. I don’t want to install it from the official repository because it is missing these special flags (use of extra processing power).
However, I tried to remove it, but again, no luck.
