leapp preupgradeしたら使ってないPostgreSQLのリポジトリがないと怒られる件

Posted at

ELevating CentOS 7 to RockyLinux 8

ZABBIX5.0+PostgreSQL13環境のCentOS7からRocky8へのアップグレードを試行中。
AlmaLinuxのこの記事を参考に実施したところ

leapp preupgradeを実行すると、以下のように怒られる

そもそもPostgreSQL11使ってないし、
このhttps://download.postgresql.org/pub/repos/yum/11/redhat/rhel-8-x86_64/repodata/repomd.xmlなんていうのは存在しないURLだし。。

どうやらleappが勝手に作ってるRepoファイルがある

/var/lib/leapp/el8userspace/etc/yum.repos.d/配下にもrepoファイルがあるんだけど、これをいくらイジってもleapp preupgradeすると再作成されて無駄。
/var/log/leapp/leapp-preupgrade.logを確認すると、どうやら雛形にしているファイル?があるらしく、そっちをイジるのが正解っぽい。
/etc/leapp/files/vendors.d/postgresql.repoel8-pgdg11をコメントアウト。

/etc/leapp/files/vendors.d/postgresql.repo
#[el8-pgdg11]
#name=PostgreSQL 11 for RHEL / Rocky 8 - $basearch
#baseurl=https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-8-$basearch
#enabled=1
#gpgcheck=1
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-PGDG
#module_hotfixes=true

ついでにpostgresql_map.jsonも怪しいので編集しちゃう。
jsonなのでコメントアウト出来ないから、念のためバックアップを残しておくこと。

これでleapp preupgradeしても怒られなくなった。
PostgreSQLに限らず、同じような事象で苦しむ人の助けになれば良いなと思ってメモ書き程度ですが、残しておくことにします。
