昨天通过’sudo do-release-upgrade -d’将ubuntu 20.04升级到了ubuntu 22.04 (注：从LTS版本升级到LTS版本一般得等8月份第1个小版本出来才会正式将22.04标为LTS，在此之前应加-d参数).

autofs与sssd冲突的问题

升级之后，今天发现一个问题，autofs不好使了．通过下列命令调试时看到了sssd字眼．

sudo systemdctl stop autofs
sudo automount --debug -f

发现sssd无法启动，将sssd删除之后(apt purge sssd) autofs就恢复正常了．

nfsv4不work的问题

还有一个问题，在升级之后nfs4不work了（mount -t nfs -s -o nfsvers=4,rw,rsize=32768,wsize=32768 nas:/Public /nas），待查，先不得不降到nfs3

$ cat /etc/auto.direct
/nas    -fstype=nfs,nfsvers=3,rw,rsize=32768,wsize=32768     nas:/Public
$ cat /etc/auto.direct
/nas    -fstype=nfs,nfsvers=3,rw,rsize=32768,wsize=32768     nas:/Public

使用下列方法debug nfs(也可使用：rpcdebug -m nfs -s all）, 并看到下列错误，似乎是kernel 5.15与nfsv4(nfs-common)不work　－　https://bugzilla.redhat.com/show_bug.cgi?id=1719903

# https://www.serverstack.com/blog/2012/11/21/debugging-nfs-file-access-on-server-and-client-side/index.html
sudo rpcdebug -m nfs -s proc
sudo tail -f /var/log/syslog
sudo mount -t nfs -o nfsvers=4 nas:/Public /mnt/tmp

正常的切换到ubuntu 18.04，nfsv4正常并有下列日志：

无法ssh到dropbear的问题

另外，还遇到一个ssh问题，报：no matching host key type found. Their offer: ssh-rsa, 通过下列方法解决：

$ tail -n3 /etc/ssh/ssh_config
    KexAlgorithms +diffie-hellman-group1-sha1
    HostkeyAlgorithms +ssh-dss,ssh-rsa
    PubkeyAcceptedKeyTypes +ssh-dss,ssh-rsa

gnome lunar-calendar插件无法显示中文的问题

升级到ubuntu 22.04之后，发现我之前在20.04下一直使用的一些gnome插件消失了(如跨时区显示时间，如天气，截屏, 具体见：　https://extensions.gnome.org/local/ ). 在运行下列命令并重启机器之后截屏恢复了，但天气和跨时区显示时间的还是未恢复．

sudo apt install gnome-shell-extensions gnome-tweaks gnome-shell-extension-manager chrome-gnome-shell -y
then need to reboot the machine
sudo systemctl status display-manager

另外，发现之前安装的农历日历无论怎么弄也无法显示中文了，只好临时禁用掉　－　https://extensions.gnome.org/extension/675/lunar-calendar/

其他设置

也做了其他一些设置：

# avoid: update-notifier.desktop[132410]: Cannot stat file /proc/3829/fd/1023: Permission denied
sudo apt purge update-notifier update-notifier-common -y

# avoid: /usr/lib/systemd/system-generators/netplan failed with exit status 1.
sudo mv /etc/netplan/01-network-manager-all.yaml /etc/netplan/01-network-manager-all.yaml_bak
sudo netplan apply
