Hi everybody, the situation is the following: on a RHEL 8.5 machine, alongside GitLab installed as omnibus-package: ``` ➜ ~ yum --noplugins repolist -v --repo gitlab_gitlab-ee YUM version: 4.7.0 cachedir: /var/cache/dnf Repo-id : gitlab_gitlab-ee Repo-name : gitlab_gitlab-ee Repo-updated : Tue 07 Dec 2021 12:26:11 AM CET Repo-pkgs : 202 Repo-available-pkgs: 202 Repo-size : 175 G Repo-baseurl : https://packages.gitlab.com/gitlab/gitlab-ee/el/8/x86_64 Repo-expire : 300 second(s) (last: Wed 08 Dec 2021 03:38:20 PM CET) Repo-filename : /etc/yum.repos.d/gitlab_gitlab-ee.repo Total packages: 202 ``` I want to have td-agent installed (which is a distribution of fluentd): ``` ➜ ~ yum --noplugins repolist -v --repo treasuredata YUM version: 4.7.0 cachedir: /var/cache/dnf Last metadata expiration check: 0:53:52 ago on Wed 08 Dec 2021 02:51:07 PM CET. Repo-id : treasuredata Repo-name : TreasureData Repo-revision : 1638509802 Repo-updated : Fri 03 Dec 2021 06:36:42 AM CET Repo-pkgs : 6 Repo-available-pkgs: 6 Repo-size : 84 M Repo-baseurl : http://packages.treasuredata.com/4/redhat/8/x86_64 Repo-expire : 172,800 second(s) (last: Wed 08 Dec 2021 02:51:07 PM CET) Repo-filename : /etc/yum.repos.d/td.repo Total packages: 6 ``` Now, trying to install td-agent results in ``` Error: Transaction test error: file /usr/lib/.build-id/43/628674f17ad8eef26bdfe36f12978af5c53c4a from install of td-agent-4.2.0-1.el8.x86_64 conflicts with file from package gitlab-ce-14.2.0-ce.0.el8.x86_64 file /usr/lib/.build-id/4b/41a98372f36876cd1be483fa30caddeb0c3d5f from install of td-agent-4.2.0-1.el8.x86_64 conflicts with file from package gitlab-ce-14.2.0-ce.0.el8.x86_64 file /usr/lib/.build-id/6c/c52279cc0c5eb99a5330fe3e093851f62d6715 from install of td-agent-4.2.0-1.el8.x86_64 conflicts with file from package gitlab-ce-14.2.0-ce.0.el8.x86_64 file /usr/lib/.build-id/ce/3452804469ea64798b8df6a5d35400170b04ef from install of td-agent-4.2.0-1.el8.x86_64 conflicts with file from package gitlab-ce-14.2.0-ce.0.el8.x86_64 ``` Apparently, both packages contain the same files in /usr/lib/.build-id/ which are symbolic links to some binaries. Let's see what hides behind those links: ``` ➜ ~ readlink --canonicalize /usr/lib/.build-id/43/628674f17ad8eef26bdfe36f12978af5c53c4a /opt/gitlab/embedded/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/3.0/nokogiri.so ➜ ~ readlink --canonicalize /usr/lib/.build-id/4b/41a98372f36876cd1be483fa30caddeb0c3d5f /opt/gitlab/embedded/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/2.7/nokogiri.so ➜ ~ readlink --canonicalize /usr/lib/.build-id/6c/c52279cc0c5eb99a5330fe3e093851f62d6715 /opt/gitlab/embedded/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/2.5/nokogiri.so ➜ ~ readlink --canonicalize /usr/lib/.build-id/ce/3452804469ea64798b8df6a5d35400170b04ef /opt/gitlab/embedded/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/2.6/nokogiri.so ``` Okay, and what is included in td-agent? ``` ➜ ~ repoquery --list td-agent | grep 'nokogiri-1.11.7-x86_64-linux/lib/nokogiri/[[:digit:]].[[:digit:]]/nokogiri.so' Last metadata expiration check: 0:00:47 ago on Wed 08 Dec 2021 03:54:35 PM CET. /opt/td-agent/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/2.5/nokogiri.so /opt/td-agent/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/2.6/nokogiri.so /opt/td-agent/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/2.7/nokogiri.so /opt/td-agent/lib/ruby/gems/2.7.0/gems/nokogiri-1.11.7-x86_64-linux/lib/nokogiri/3.0/nokogiri.so ``` Thus, both packages ship their own ruby distributions which include several nokogiri gems, but they also include build-ids for nokogiri as symbolic links, with the links in gitlab-ee pointing to nokogiri binaries from ruby shipped with gitlab-ee and the links in td-agent to binaries from ruby shipped with td-agent. After research, it seems that the only way to work around it is to install the packages manually using `rpm --install --replacefiles`. But this is an unsatisfying solution since I can no longer update my system with yum update. I've already tried to find support from nokogiri-project (R1) and on RHEL-community forum (R2). Unfortunately, both postings were without success, no one of them is responsible for maintaining the packages. So I am asking here: maybe it would be possible to remove those build-id links from GitLab-RPM?
