Run omero server on Debian 10

Installation tested via travis

Corresponding doc PR https://github.com/ome/ome-documentation/pull/2084

Looks good. Tested it with a debian10 VM, works well, omero-server running. Although I couldn't connect to it with Insight from the host machine, but that's probably some port forwarding or firewall issue.

[dominikl]

Well actually, there is something weird going on. Sudo'ed to omero-server user, wanted to run diagnostics:

omero-server@debian10:/opt/omero/server/OMERO.server/bin$ ./omero admin diagnostics

[jburel]

you will have to do: . /home/omero-server/settings.env omero .... to export variable like OMERODIR or PATH

[dominikl]

Thanks. That works now. But can't login locally either:

omero-server@debian10:/opt/omero/server/OMERO.server/bin$ ./omero login
Server: [localhost:4064]
Username: [omero-server]root
Password:
WARNING:omero.client:..Ignoring error in client.__del__:<class 'Ice.SocketException'>
InternalException: Failed to connect: Ice.SocketException:
Cannot assign requested address

I'll try to run the install script again, this time carefully looking for errors in the output...

[jburel]

So far

• set omero config set Ice.IPv6 0
• comment out line with ip6-* in /etc/hosts I can now run omero login -s 127.0.0.1 -p 4064 -u root -w omero_root_password and omero login -s localhost -p 4064 -u root -w omero_root_password and have the same error

  WARNING:omero.client:..Ignoring error in client.__del__:<class 'Ice.ProtocolException'>
  InternalException: Failed to connect: exception ::Ice::ProtocolException
  {
  reason = SSL error occurred for new outgoing connection:
  remote address = 127.0.0.1:4064
  no protocols available
  }

Downgrading openssl from 1.1.1d to 1.1.0f did not change anything

[jburel]

I have tried the various protocols supported by Ice

• SSL3 -> IceSSL: OpenSSL was build without SSLv3 support
• TLS1 or TLS1_1 -> no protocols available
• TLS1_2 -> tlsv1 alert internal error: SSL alert number 80

running out of ideas

[dominikl]

I have the same issues with a debian VM installed from scratch (previously I was using vagrant). But I get another strange issue, when I run omero admin diagnostics I get FileNotFoundError: [Errno 2] No such file or directory: 'icegridadmin': 'icegridadmin'.

[mtbc]

Huh, did zeroc-ice-utils get installed?

[dominikl]

Apparently not... ah I had some bdist_wheel errors when running the install script. Maybe that's why? Still don't get it what this bdist_wheel stuff is.

[jburel]

ignore the bdist_wheel I do not have the error you indicated when running in docker

[dominikl]

No luck with a vanilla debian10 installation either. I also tried to install the ice stuff from zeroc directly, to rule out potential issues in https://github.com/ome/zeroc-ice-debian10 . Then also tried to use the python lib from zeroc too via pip install zeroc-ice=='3.6.5'. In either case I got the

InternalException: Failed to connect: exception ::Ice::ProtocolException
{
    reason = SSL error occurred for new outgoing connection:
remote address = 127.0.0.1:4064
no protocols available
}

Whish one could get more details about the error...

Btw @mtbc was right, when I ran the omero install script zeroc-ice-utils was missing. After installing it manually I didn't get the error about the missing icegridadmin any longer.

[dominikl]

Good to merge now 👍 Tested again with an vanilla debian10 VM in virtualbox.

[joshmoore]

@jburel : did I understand correctly that you wouldn't merge this until the omeroweb-install PR is passing as well?

[jburel]

I think it is better to have both at the same time. I think we should not include it in the 5.6 tag

[dominikl]

Makes sense. Btw, just followed the web installation docs for Ubuntu 18.04. Works fine, no problems. Just had to use the ice package for debian10 obviously.

[jburel]

Merging for 5.6
