"Not enough space left" error even with "nodiskspace" option set

[tasso85]

I am currently facing an issue with an installer created with makeself, which when run would return the following error message:

[root@srv614 ~]# ./upgrade_626suite_20.1.0_to_20.2.0_encrypted.run.xz
Copying to a temporary location...
Verifying archive integrity...  100%    100%   All good.
Uncompressing Aggiornamento 626 Suite V64 alla versione 20.2.0
Not enough space left in /tmp (38159336 KB) to decompress /tmp/makeself.26402.200526083910.24453/makeself (12055782109125213 KB)
Use --nodiskspace option to skip this check and proceed anyway
Consider setting TMPDIR to a directory with more free space.

The problem is that, even when putting the option suggested by the error message itself, the error remains the same:

[root@srv614 ~]# ./upgrade_626suite_20.1.0_to_20.2.0_encrypted.run.xz --nodiskspace
Copying to a temporary location...
Verifying archive integrity...  100%    100%   All good.

The error happens on a CentOS 7.2.1511 server, yet not on a CentOS 7.8.2003; also I think that the size of the archive reported by makeself (12055782109125213 KB) is quite wrong, the RUN file itself is less than 100 MB.

I think you can disregard this, re-creating the installer with the latest version 2.4.2 seems to have solved the issue, sorry for the wrong report.

After another check, I found out that some error still persists.

In fact, when using the makeself script on WSL, I just noticed this:

Header is 695 lines long

About to compress Infinity KB of data...
Adding files to archive named "./upgrade.run.xz"...

It says "Infinity KB", which doesn't look right.
