I am running an up-to-date Ubuntu system on a physical PC:
Linux 5.13.0-35-generic x86_64
NAME="Ubuntu"
VERSION="20.04.4 LTS (Focal Fossa)"
and I am experiencing the following collection of issues:
- Boot times are suddenly 10x longer than "before"
- The DNS configuration (the DNS addresses to use) is not persisted across reboots (after reboot, need to netplan apply and it is fine)
- It is impossible to login through the UI (with a directly connected monitor and keyboard): the screen accepts a password then asks again -- the "login loop"
These problems started happening after I replaced the main router to which the device is connected. It is configured with a static IP address:
xxxxxxxxxxxx:~$ cat /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
ethernets:
enp1s0:
addresses: [192.168.8.221/24]
gateway4: 192.168.8.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]
dhcp4: no
The PC is connected over a wired network to a consumer router that is in turn directly connected to a FIOS ONT. As noted, this problem started after I replace the Verizon-supplied router with my own (and at the same time, the connection speed to the device was increased to 1 GBPS from 100 MBPS).
I literally have no idea where to look for a solution to this -- any advice is welcomed!
