上一篇讲了Proxmox7目前一些不支持的地方。比如sit隧道之类的。
但是在我们升级Proxmox7的时候也需要注意一些地方，在这里我把我遇到的都记录下来。
先把参考教程放上。
root强制登录：
cat >> /etc/ssh/sshd_config << EOF
PasswordAuthentication yes
PermitRootLogin yes
EOF
service ssh restart
这个应该算是Debian的要求，因为我买的独服不允许root登录，我就一块记录了。
apt-get dist-upgrade升级失败
W: (pve-apt-hook) !! WARNING !!
W: (pve-apt-hook) You are attempting to remove the meta-package 'proxmox-ve'!
W: (pve-apt-hook)
W: (pve-apt-hook) If you really want to permanently remove 'proxmox-ve' from your system, run the following command
W: (pve-apt-hook) touch '/please-remove-proxmox-ve'
W: (pve-apt-hook) run apt purge proxmox-ve to remove the meta-package
W: (pve-apt-hook) and repeat your apt invocation.
W: (pve-apt-hook)
W: (pve-apt-hook) If you are unsure why 'proxmox-ve' would be removed, please verify
W: (pve-apt-hook) - your APT repository settings
W: (pve-apt-hook) - that you are using 'apt full-upgrade' to upgrade your system
E: Sub-process /usr/share/proxmox-ve/pve-apt-hook returned an error code (1)
E: Failure running script /usr/share/proxmox-ve/pve-apt-hook
这个报错是因为Proxmox6旧的内核不兼容最新7的内核。需要删除旧的内核再次运行 apt-get dist-upgrade 即可。
apt remove linux-image-amd64
Proxmox库无法授权
E: Failed to fetch https://enterprise.proxmox.com/debian/pve/dists/bullseye/InRelease 401 Unauthorized [IP: 2607:5300:203:7dc2::162 443]
E: The repository 'https://enterprise.proxmox.com/debian/pve bullseye InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
这个问题是由于自带的库有收费的版本的deb库，需要屏蔽这些库替换成免费的版本。
nano /etc/apt/sources.list
deb http://ftp.debian.org/debian bullseye main contrib
deb http://ftp.debian.org/debian bullseye-updates main contrib
#PVE pve-no-subscription repository provided by proxmox.com,
#NOT recommended for production use
deb http://download.proxmox.com/debian/pve bullseye pve-no-subscription
#security updates
deb http://security.debian.org/debian-security bullseye-security main contrib
同时要将以下两个库屏蔽掉：
nano /etc/apt/sources.list.d/pve-install-repo.list
nano /etc/apt/sources.list.d/pve-enterprise.list
然后再次升级即可。
