我正在运行 Ubuntu 19-04。
我正在尝试安装 ifupdown2
当我做
dpkg -i ../ifupdown2_1.2.1_all.deb
它说
Selecting previously unselected package ifupdown2.
dpkg: considering removing ifupdown in favour of ifupdown2 ...
dpkg: no, cannot proceed with removal of ifupdown (--auto-deconfigure will help):
pppoeconf depends on ifupdown (>= 0.7.44~)
ifupdown is to be removed.
dpkg: regarding ../ifupdown2_1.2.1_all.deb containing ifupdown2:
ifupdown2 conflicts with ifupdown
ifupdown (version 0.8.34ubuntu2) is present and installed.
dpkg: error processing archive ../ifupdown2_1.2.1_all.deb (--install):
conflicting packages - not installing ifupdown2
Errors were encountered while processing:
../ifupdown2_1.2.1_all.deb
有人知道这个问题的解决办法吗？
答案1
cat /etc/network/interfaces
回
# ifupdown has been replaced by netplan(5) on this system. See
# /etc/netplan for current configuration.
# To re-enable ifupdown on this system, you can run:
# sudo apt install ifupdown
我希望我的网络连接由 Network Manager 而不是 Netplan 控制。如果必须安装 ifupdown，那么我想要 ifupdown2。
我试过
apt install ifupdown

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
ifupdown2 : Conflicts: ifupdown
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or
specify a solution).
所以我做了
apt --fix-broken install

The following packages were automatically installed and are no longer
required:
rsplib-docs spl-dkms
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
pppoeconf
0 upgraded, 0 newly installed, 1 to remove and 10 not upgraded.
1 not fully installed or removed.
After this operation, 135 kB disk space will be freed.

然后我就这么做了
dpkg -i ../ifupdown2_1.2.1_all.deb
返回

似乎已经安装了
apt list --installed | grep -i ifupdown2
WARNING: apt does not have a stable CLI interface. Use with caution in
scripts.
ifupdown2/now 1.2.1 all [installed,upgradable to: 1.2.5-1]
然后我在 /etc/network/interfaces 中添加了以下内容
auto lo
iface lo inet loopback
auto enp11s0
iface enp11s0 inet dhcp
添加
[ifupdown]
managed=false
到 /etc/NetworkManager/NetworkManager.conf 并执行
systemctl stop systemd-networkd
systemctl disable systemd-networkd
service NetworkManager restart
一切似乎都还好，但如果有人知道如何将 ifupdown2 从 1.2.1 升级到 1.2.5-1 那就好了。
