Application has issues after upgarde to Tomcat 7.0.52-1ubuntu0.6

Asked by bzlom on 2016-07-08

Hello,

We are running Ubuntu 14.04.4 LTS. After upgrading to the recently released Tomcat 7.0.52-1ubuntu0.6 from 7.0.52-1ubuntu0.3 some of our redirects stopped working, ex. www.site.com/webapp wouldn't redirect to www.site.com/webapp/login.action any longer.

At the same time when decided to rollback to the previous version 7.0.52-1ubuntu0.3 - it wasn't possible. Could you advise on how can we rollback to the previous stable version until we are able to identify and decide if we want to use 7.0.52-1ubuntu0.6?

We are also suffering from exactly this problem. I was hoping to easily roll back but apt-cache reverse provides no alternative versions.

You can download 7.0.52-1ubuntu0.3 directly from launchpad:

https://launchpad.net/~ubuntu-security/+archive/ubuntu/ppa/+build/7559378

Download the packages linked at the bottom of the page that correspond to the packages you currently have installed, and then use "dpkg -i" to manually install them.

I can confirm that rolling back to the previous version (and holding the rollback from future updates) as per Marc's advice has resolved my issue on three separate servers. Is this a bug that's likely to be resolved? Shall I post a bug report?

Downloading from launchpad is a solution that I have already implemented - and it works. But it is a rough workaround. We need to have a fast and easy way of rolling back, to at least the previous release (from the Ubuntu repo), in case the update broke some functionality in our app.

I realize that we can also create our own PPA and save all the necessary/stable packages and their dependencies there, and work with it in case things go south - but I expect the Ubuntu repo to at least have the previous stable release.

HI,

Last nights security update seems to have restated this bug. This from apt-history:

Start-Date: 2016-07-12 06:45:23
Upgrade: libnspr4:amd64 (4.10.10-0ubuntu0.14.04.1, 4.12-0ubuntu0.14.04.1), libgd3:amd64 (2.1.0-3ubuntu0.1, 2.1.0-3ubuntu0.2), libservlet3.0-java:amd64 (7.0.52-1ubuntu0.3, 7.0.52-1ubuntu0.6), libnss3-nssdb:amd64 (3.21-0ubuntu0.14.04.2, 3.23-0ubuntu0.14.04.1), libtomcat7-java:amd64 (7.0.52-1ubuntu0.3, 7.0.52-1ubuntu0.6), libnss3:amd64 (3.21-0ubuntu0.14.04.2, 3.23-0ubuntu0.14.04.1), libservlet3.0-java-doc:amd64 (7.0.52-1ubuntu0.3, 7.0.52-1ubuntu0.6)
End-Date: 2016-07-12 06:45:24

I suspect it is the libservlet3.0 update causes the problem but it is only evident after you restart tomcat7 - I have two concurrent instances, one I restarted after the update which shows the routing problem described in the question. The other hasn't been restarted and seems to be working fine.

Can you help with this problem?
