I want to install Oracle SQL Developer on Debian. Oracle doesn't provide a .deb installation package, only a .rpm installer. So I'm trying to use alien to convert the .rpm package to .deb

Some details on my environment...

I'm running Debian in the Linux container of Chrome OS (Crostini) on a Snapdragon 7C equipped Chromebook

uname -a -> Linux penguin 5.10.101-14958-ge846e44211d8 #1 SMP PREEMPT Sun Mar 27 19:06:58 PDT 2022 aarch64 GNU/Linux

cat /etc/debian_version -> 11.3

alien version 8.95.4

RPM version 4.16.1.2

I download the .rpm package (sqldeveloper-21.4.3-063.0100.noarch.rpm) from here here

and run sudo alien --to-deb sqldeveloper-21.4.3-063.0100.noarch.rpm

I get about 20 warnings of...

warning: RPM v3 packages are deprecated: sqldeveloper-21.4.3-063.0100.noarch

And then it errors out with...

Package build failed. Here's the log:

I've tried using fpm as suggested here that actually creates a .deb file but when trying to install that it errors out with...

dpkg: error processing archive sqldeveloper_21.4.3-063.0100_all.deb (--install):
 parsing file '/var/lib/dpkg/tmp.ci/control' near line 7 package 'sqldeveloper':
 'Depends' field, invalid package name '/bin/sh': must start with an alphanumeric character
Errors were encountered while processing:
 sqldeveloper_21.4.3-063.0100_all.deb

Any advice gratefully received...

Thanks!
