I have a custom package installed on my Ubuntu 10.10, and trying to remove it, I got:

$ sudo dpkg -r package
sub-process script post-installation installed returne an error state 127

(the message returned from the command was translated from portuguese(br).

So, I noted that on the installation script of this package, what it did was create an entry on my startup, create a folder on /opt and create a user.

I removed all it created. But now, I just want to remove it from dpkg list, because I want to make my linux like if I never installed this package.

How can I do this?

This question came from our site for professional and enthusiast programmers.

You may need to manually remove the package using:

sudo dpkg --purge --force-all package

Replace package with the name of the package.

Do note: its recommended to report a bug if the package is not yours or is unknown to you what the script does.

doesn't work when pre-removal script fails, as with xmail. – jcomeau_ictx Jan 18 '15 at 23:04
@jcomeau_ictx of course... the question is about post-removal, not about pre. – Braiam Jan 19 '15 at 0:27

trying to remove xmail with dpkg --purge --force-all xmail failed because the pre-removal script was exiting with a failure attempting to stop the xmail daemon. I found the solution here:

specifically, I edited /var/lib/dpkg/info/xmail.prerm and changed || exit $! to || true

I don't understand the downvote. the other solution doesn't cover all cases, and this provides some help for the remainder. – jcomeau_ictx Apr 7 at 13:47
If I have to guess, you answer "failed because the pre-removal script", this questions is about the "post-installation" script. You aren't answering the currently asked question. – Braiam Apr 7 at 23:34
OK, fair enough, thanks. – jcomeau_ictx Apr 8 at 3:01
