Hi,
Just registered here to say “thank you” to you all! You just saved me quite a few additional hours of frustration while migrating to my new workstation (CentOS 6.10 → RHEL8.5)…
What I did on my RedHat Enterprise Linux 8.5, first I removed RedHat’s version of Thunderbird:
# dnf remove thunderbird
Then, i dumped the Rocky plus repository into /etc/yum.repos.d/Rocky-plus.repo as superuser root in disabled form:
[plus]
name=Rocky Linux $releasever - Plus
mirrorlist=http://mirrors.rockylinux.org/mirrorlist?arch=$basearch&repo=rockyplus-$releasever
#baseurl=http://dl.rockylinux.org/$contentdir/$releasever/rockyplus/$basearch/os/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
To make gpgcheck=1 work, I had to import Rocky Linux’ official GPG key:
# rpm --import https://dl.rockylinux.org/pub/rocky/RPM-GPG-KEY-rockyofficial
Blacklisted RedHat’s thunderbird package, similar to what jlehtone mentioned (I had to change the repo name as seen below):
# dnf config-manager --save --setopt=rhel-8-for-x86_64-appstream-rpms.excludepkgs=thunderbird
Alright, now the repository isn’t enabled by default (not sure if it would be safe after all), so I explicitly request thunderbird for installation from it:
# dnf --enablerepo=plus install thunderbird
And it’s solved! While not actually running Rocky Linux, it still made my life on RHEL8 a little easier, so again: Thank you for that!
