Kind of complicated, but works. Proxmox uses NoVNC to connect to the primary user (in my case, pi=1000). I can start another Xsession at :1 but the desktop sharing doesn’t work well. pcmanfm-qt loads new windows in the :0 session instead of :1, and things aren’t well separated. Easier to just create a new user…

InfluxDB as an example (taken from here): 1. Obtain and verify the new key : wget -q https://repos.influxdata.com/influxdata-archive_compat.key gpg –with-fingerprint –show-keys ./influxdata-archive_compat.key 2. Install the new key: cat influxdata-archive_compat.key | gpg –dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null 3. Update your APT sources to use the new key: echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg] https://repos.influxdata.com/debian stable main' |…

OpenVPN will fail to start in an unprivileged LXC with the following error as shown in journalctl -xeu openvpn@server: ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2) The Proxmox wiki has a nice guide to solving this problem.

journal size grows huge in a default debian installation, but can be limited by editing /etc/systemd/journald.conf and adding a limit on the line SystemMaxUse=. Something like 100M.

Sometimes the GRUB bootloader gets messed up, and you get dumped into the EFI Shell. A few key commands to get things working again… map gets a list of all the discovered partitions FS0: gets you to the file structure of the FS0 partition bcfg boot dump -b lists all the EFI boot entries bcfg…

Debian LXQT desktop environment (DE) doesn’t come with a pre-installed VNC server. I usually want to log into an existing Xsession, and X11VNC is the easiest VNC server I’ve found to do that. Others like TigerVNC or TightVNC were harder to configure to connect to existing X sessions. So I did sudo apt install x11vnc…
