Cta-frontend fail to start

Troubleshooting
1

Hi,

Trying to setup a standalong environment for CAT + dCache.

taped and rmcd seem fine, however, cta-frontend fails to start.
------ Protection system initialization completed.
Config Routing for pps06.lcg.triumf.ca: local pub4 prv4 pub6 prv6

I see the required libs are there with different version though.

[root@pps06 ~]# rpm -qf /usr/lib64/libXrdSsi-5.so
xrootd-server-libs-5.4.2-1.el7.x86_64
[root@pps06 ~]# rpm -qf /usr/lib64/libXrdSsiCta.so
cta-frontend-5.8.7-1.el7.cern.x86_64

Anyone has idea which package is missing ?

Used the CTA public repo

https://cta-public-repo.web.cern.ch/cta-5/el-7/cta/x86_64/

And, followed up the dCache CTA BOOK,

Of course I skipped some broken packages when doing that. Today, I tried to use the latest version(just came out Sep. 18th). I got very similar package missing/broken info like this.

Error: Package: cta-cli-5.10.0-2.el7.cern.x86_64 (cta-public-5-centos7)
Requires: libgrpc.so.7()(64bit)
Available: grpc-1.20.1-1.el7.x86_64 (centos-openstack-train)
libgrpc.so.7()(64bit)

I do have these package installed though(couldn’t fine specified required version)

rpm -qa | grep grpc

grpc-devel-1.36.0-1.el7.x86_64
cta-frontend-grpc-5.8.7-1.el7.cern.x86_64
grpc-1.36.0-1.el7.x86_64

rpm -qa | grep protobuf

protobuf-c-1.0.2-3.el7.x86_64
protobuf3-3.3.1-2.el7.cern.x86_64
eos-protobuf3-3.17.3-1.el7.cern.eos.x86_64
protobuf-2.5.0-8.el7.x86_64

Anyone have idea which exactly grpc and protobuf version is needed for CTA-frentend ? and where is the best location I can get them ?

thank you

Dear Simon,
could you try the Public RPMs installation instructions: this should contain everything you need to install CTA from public repositories.
Let us know if this procedure works for you.
