Drush unable to selfupdate -- Cannot determine release date for drush

Hi,

To update Drush in quickstart, do the following (copied from the project home page):

cd ~/quickstart
git pull
bash -x update.sh

Drush in Quickstart is checked out from the git repo, not the packaged zip on drupal.org. This makes several things easier, but apparently "drush selfupdate" doesn't know how to deal with this situation.

Marking not a bug for Quickstart, but I think it's a bug for Drush.

Good luck!

update.sh displays the following, but doesn't actually appear to do anything to upgrade Drush:

quickstart@qs091:~/quickstart$ bash -x update.sh 
+ cd /home/quickstart/quickstart
+ DRUSH=7.x-4.4
+ DRUSH_MAKE=6.x-2.2
+ echo '*** Run '\''git pull'\'' before running this to get latest version ***'
*** Run 'git pull' before running this to get latest version ***
+ echo 'Updating Drush to 7.x-4.4'
Updating Drush to 7.x-4.4
+ cd /home/quickstart/drush
+ git checkout 7.x-4.4
+ echo 'Updating Drush Make to 6.x-2.2'
Updating Drush Make to 6.x-2.2
+ cd /home/quickstart/.drush/drush_make
+ git checkout 6.x-2.2

The messages might be confusing, but it does work.

Why is the detour through git pull necessary ?
Because Drush is now at 4.5 but quickstart only updates to 4.4
Quickstart has to be updated first to reflect this change ?

bump....

running update.sh didn't do anything for me. Drush still reports that it is 4.4. There have been some big improvements in Drush 4.5 that I think we need.

One example is using git to apply patches in a make file. A lot of distributions won't install because of the installed Drush 4.4.

If anyone knows of a way to install the latest, I'm all ears.

To update Drush to 4.5

cd ~/drush # where it's installed
git pull # grab the latest code
git tag # see the list of available official releases
git checkout 7.x-4.5 # Important ! Drush quickstart-create doesn't work with the latest 5.x-dev

Thanks @DjebbZ, that worked. Just what I needed.

You're welcome gmclelland :)

Marking it "needs work" because update.sh needs to change the Drush variable to update to 4.5. But I have no idea how to submit a patch for this image, neither if the file is actually versioned by Git to submit a patch... Maintainers ?

In case it may help someone else, the equivalent commands for Drush Make are:

cd /home/quickstart/.drush/drush_make
git pull
git tag
git checkout 6.x-2.3

FWIW, I'm having this same problem. I tried with both apt-get and pear installations, neither handled the self-update properly. Once I checked it out using git, I could do it (although I had to re-run pear to get the symbolic link working for /usr/bin/drush)

Is there a solution for fixing self updating that doesn't require starting with a clean git checkout?

Any chance to update Quickstart so that bash -x update.sh brings Drush to version 5 while making sure that quickstart-create (see #6) keeps functioning under Drush 5? Thanks!

See the patch at #1511728-2: Make quickstart-create compatible with Drush 5, @Vacilando.

Would you like to back up your current drush version 4.4 to /home/quickstart/drush-backups/unknown/20120503235138 and replace it with drush 5.1? (y/n): y

When i try:
quickstart@qs10:~$ drush dl drush
I'm getting:
File drush-7.x-5.7.tar.gz is corrupt (wrong md5 checksum).
no matter how many times I try I keep getting the md5 checksum error.

Can I fix this?

hmm seems I needed to be root this worked:
quickstart@qs10:~$ sudo drush dl drush

#6 worked great for me. Just getting involved with drush, had v 4.4 on a Quickstart 1.0 vm. Now it's at 5.8 and I'm all set. Thanks!
(initially got the same "unable to update" msg when I tried drush self-update)
