Title: Actor vsftpd_config_read
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe3 in position 3736: ordinal not in range(128)

エラーの内容を見ると、vsftpdのコンフィグファイルにasciiでない文字、たぶん日本語、が含まれているのが原因っぽいですね。
vsftpdのコンフィグ(たぶん /etc/vfstpd.conf)を修正してみてはいかがでしょうか。

/etc/vsftpd/vsftpd.conf の中に含まれている日本語コメントを全て削除して #leapp preupgrade を実行したところ、コンソールメッセージが下記のように変わりました。 Errors:は0になりましたが、 Inhibitors:が3に増えました。－－－－－ ============================================================ REPORT OVERVIEW ============================================================ Upgrade has been inhibited due to the following problems: 1.

Remediation: [hint] Remove all but one kernel-devel packages before running Leapp again. [command] yum -y remove kernel-devel-3.10.0-1160.119.1.el7 kernel-devel-3.10.0-1160.105.1.el7 kernel-devel-3.10.0-1160.118.1.el7 kernel-devel-3.10.0-1160.108.1.el7 Key: 8ceea81afbbb1a329b7d82ca7212b21509e5b256 ---------------------------------------- Risk Factor: high (inhibitor) Title: Upgrade requires links in root directory to be relative Summary: After rebooting, parts of the upgrade process can fail if symbolic links in / point to absolute paths. Please change these links to relative ones.

Key: 45608d77dbf0f5b3c0903831a3130c641eb60889 ---------------------------------------- Risk Factor: high Title: Difference in Python versions and support in RHEL 8 Summary: In RHEL 8, there is no 'python' command. Python 3 (backward incompatible) is the primary Python version and Python 2 is available with limited support and limited set of packages. If you no longer require Python 2 packages following the upgrade, please remove them. Read more here: https://red.ht/rhel-8-python Remediation: [hint] Please run "alternatives --set python /usr/bin/python3" after upgrade Key: 0c98585b1d8d252eb540bf61560094f3495351f5 ---------------------------------------- Risk Factor: high Title: GRUB2 core will be automatically updated during the upgrade Summary: On legacy (BIOS) systems, GRUB2 core (located in the gap between the MBR and the first partition) cannot be updated during the rpm transaction and Leapp has to initiate the update running "grub2-install" after the transaction. No action is needed before the upgrade. After the upgrade, it is recommended to check the GRUB configuration.

Summary: The following RHEL 7 device drivers are no longer maintained RHEL 8: - e1000 - e1000 Key: 0ff2413fd3cb0358736bf9be597f4dbdf58f2c4d ---------------------------------------- Risk Factor: medium Title: spamc no longer allows specifying the TLS version and no longer supports SSLv3 Summary: spamc no longer allows using the "--ssl" option with an argument specifying the TLS version - the option can only be used without an argument. Also, spamc no longer supports SSLv3. Remediation: [hint] Please update your scripts and configuration, if there are any.

Remediation: [hint] Please update your scripts and configuration, if there are any. Key: 174eb9ad0aed3013f829e892ee753967058f51d5 ---------------------------------------- Risk Factor: medium Title: The type of the spamassassin systemd service has changed Summary: The type of spamassassin.service has been changed from "forking" to "simple". The spamassassin sysconfig file will be updated. Key: 3ed08dd692315c1f736daf2a0f533f6ebca70cc4 ---------------------------------------- Risk Factor: low Title: Some enabled RPM repositories are unknown to Leapp Summary: The following repositories with Red Hat-signed packages are unknown to Leapp: - elevate - centos-sclo-rh And the following packages installed from those repositories may not be upgraded: - python27-python-babel - leapp-upgrade-el7toel8-deps - leapp-data-almalinux - python27-python-sphinx - python27-python-tools - leapp-upgrade-el7toel8 - python27-python-virtualenv - python27-python-werkzeug - python27-python-markupsafe - python27-runtime - python2-leapp - python27-python-devel - python27-python-sqlalchemy - python27 - python27-python-pygments - python27-python-pip - python27-python-jinja2 - python27-python-docutils - python27-tkinter - python27-python-simplejson - leapp - python27-python-nose - python27-python-libs - leapp-deps - python27-python-wheel - python27-python - python27-python-setuptools Remediation: [hint] You can file a request to add this repository to the scope of in-place upgrades by filing a support ticket Key: 8e89e20c645cea600b240156071d81c64daab7ad ---------------------------------------- Risk Factor: low Title: Grep has incompatible changes in the next major version Summary: If a file contains data improperly encoded for the current locale, and this is discovered before any of the file's contents are output, grep now treats the file as binary. The 'grep -P' no longer reports an error and exits when given invalid UTF-8 data. Instead, it considers the data to be non-matching. In locales with multibyte character encodings other than UTF-8, grep -P now reports an error and exits instead of misbehaving. When searching binary data, grep now may treat non-text bytes as line terminators. This can boost performance significantly. The 'grep -z' no longer automatically treats the byte '\200' as binary data. Context no longer excludes selected lines omitted because of -m. For example, 'grep "^" -m1 -A1' now outputs the first two input lines, not just the first line. Remediation: [hint] Please update your scripts to be compatible with the changes. Key: 94665a499e2eeee35eca3e7093a7abe183384b16 ---------------------------------------- Risk Factor: low Title: sa-update no longer supports SHA1 validation Summary: sa-update no longer supports SHA1 validation of filtering rules, SHA256/SHA512 validation is done instead. This may affect you if you are using an alternative update channel (sa-update used with option --channel or --channelfile), or if you install filtering rule updates directly from files (sa-update --install). Key: 5f94c35aab24e5ce2033c8bec5b83902caedecc3 ---------------------------------------- Risk Factor: low Title: Dosfstools incompatible －－－－－
