Downgrading ports

Usage

by ross at 07:56:21 on December 20, 2015

I use net/minidlna on the home server to watch films over WiFi on my TV. The latest version doesn't work well so I use it to show how to downgrade a port to any previous version.

We will use portdowngrade utility to downgrade ports:

> cd /usr/ports/ports-mgmt/portdowngrade
> sudo make install clean

Let's see..

> pkg query %n-%v minidlna
minidlna-1.1.5,1

OK, we have version 1.1.5,1 installed.

> sudo service minidlna stop
> sudo pkg remove minidlna

Now we need a revision number to downgrade to:

> portdowngrade net/minidlna | less
Choose a revision from this list and run /usr/local/sbin/portdowngrade net/minidlna revision

... output skipped ...

We've got a list of revisions in reverse order. Here we can see that r403959 is when the port switched to version 1.1.5. So we need the revision before that which is r397778.

Checked out revision 397778.
You should be done-- now cd into minidlna and you can run
# make deinstall install clean

Please note that portdowngrade no longer modifies the ports tree; the
checked out port is at
/home/ross/minidlna

The utility has created minidlna directory in my home with that revision.

Let's build and install it:

> cd ~/minidlna
> make build
> sudo make install

The last step is to lock the package so it won't get updated on next "pkg upgrade" or "portupgrade -a":

> sudo pkg lock minidlna

Remeber to clear the application files before starting it (as the format of the files sometimes changes with new version):

> sudo rm -rf /var/db/minidlna
> sudo service minidlna start
