Comment 26 for bug 1998311

Jammy SRU Verification:

Fix works, 2.4.52-1ubuntu4.5 fixes the bug.

I've created the jammy container using steps from the [Test Plan] section listed above in the Bug Description and inside that container:

I have installed apache2 using:

$ apt install apache2

Then I typed in:

$ apt policy apache2

The output:

apache2:
  Installed: 2.4.52-1ubuntu4.4
  Candidate: 2.4.52-1ubuntu4.4
  Version table:
 *** 2.4.52-1ubuntu4.4 500
        500 http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu jammy-security/main amd64 Packages
        100 /var/lib/dpkg/status
     2.4.52-1ubuntu4 500
        500 http://archive.ubuntu.com/ubuntu jammy/main amd64 Packages

Then I repeated steps from [Test Plan] section.

I've noticed that nothing has changed there, so the problem still existed, because as we could see in the output, the package version was not the one where the fix is.

I have enabled proposed.

Then I've upgraded apache2 using:

$ apt install apache2=2.4.52-1ubuntu4.5

Later I've typed in:

$ apt policy apache2
to check if installed version is changed and we see that we have new version installed (with fix)

apache2:
  Installed: 2.4.52-1ubuntu4.5
  Candidate: 2.4.52-1ubuntu4.5
  Version table:
 *** 2.4.52-1ubuntu4.5 500
        500 http://archive.ubuntu.com/ubuntu jammy-proposed/main amd64 Packages
        100 /var/lib/dpkg/status
     2.4.52-1ubuntu4.4 500
        500 http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu jammy-security/main amd64 Packages
     2.4.52-1ubuntu4 500
        500 http://archive.ubuntu.com/ubuntu jammy/main amd64 Packages

Finally when I repeated steps from the [Test Plan] the problem did not exist, "Syntax OK" message. So the fix works.

Important NOTE: If a syntax error pops up in the terminal, please open /etc/apache2/sites-enabled/httpd-hcheck-ajp.conf and remember to keep:
BalancerMember ajp://127.0.0.1:8009/myapp route=app-route timeout=300 ping=3 connectiontimeout=3 hcmethod=CPING
in one line.
