After I carefully examined this code, I noticed that it leads to an error:

Error in tempdir() using /source/equivs.XXXXXX: Could not create directory /source/equivs.GUTb7J: Read-only file system at /usr/bin/equivs-build line 19.
This is obvious, because the source volume is mounted in read-only mode:
|
docker run \ |
|
--volume "${PACKDIR}:/pack:ro" \ |
|
--volume "${SOURCEDIR}:/source:ro" \ |
|
--volume "${BUILDDIR}:/build" \ |
Lets take a look at /usr/bin/equivs-build:
$ cat /usr/bin/equivs-build | grep "equivs\." -A 1
my $builddir = tempdir('equivs.XXXXXX', DIR => ($ENV{TMPDIR} || cwd), CLEANUP => 1) or
die "Cannot create temporary build dir: $!\n";Thus we should add a TMPDIR environment variable pointing to writable directory as follows:
