This article contains all problems that I encountered when upgrading Debian from 10/Buster to 11/Bullseye.
isc-dhcp-server failed to start
Unfortunately, all you see at first using systemctl status isc-dhcp-server is
Sep 30 20:51:28 host systemd[1]: isc-dhcp-server.service: Control process exited, code=exited, status=1/FAILURE Sep 30 20:51:28 host systemd[1]: isc-dhcp-server.service: Failed with result 'exit-code'. Sep 30 20:51:28 host systemd[1]: Failed to start LSB: DHCP server.
journalctl -xe -u isc-dhcp-server contains relevant information:
Okt 01 09:22:26 host dhcpd[47376]: Server starting service. Okt 01 09:22:28 host isc-dhcp-server[47361]: Starting ISC DHCPv4 server: dhcpd. Okt 01 09:22:28 host isc-dhcp-server[47361]: Launching IPv6 server only. Okt 01 09:22:28 host dhcpd[47388]: Wrote 0 NA, 0 TA, 0 PD leases to lease file. Okt 01 09:22:28 host dhcpd[47388]: Okt 01 09:22:28 host dhcpd[47388]: No subnet6 declaration for vmnet (2001:0DB8::/32). Okt 01 09:22:28 host dhcpd[47388]: ** Ignoring requests on vmnet. If this is not what Okt 01 09:22:28 host dhcpd[47388]: you want, please write a subnet6 declaration Okt 01 09:22:28 host dhcpd[47388]: in your dhcpd.conf file for the network segment Okt 01 09:22:28 host dhcpd[47388]: to which interface vmnet is attached. **
The simple solution is to add the required subnet declaration in /etc/dhcp/dhcpd6.conf:
subnet6 2001:0DB8::/32 {
range6 2001:0DB8::1 2001:0DB8::efff;
}
scanimage exits with "Out of memory" error
scanimage: open of device escl:http://127.0.0.1:60000 failed: Out of memory
It seems that version 1.0.31 has a bug that was fixed in 1.0.32, according to this bug report. Unfortunately, Debian only provides 1.0.31 to Debian 11 (there's no "updates" or "backports" package).
Providing scanimage in a chroot environment
mkdir bookworm debootstrap --arch=amd64 bookworm bookworm/ https://deb.debian.org/debian/ mount -t proc proc bookworm/proc mount -t devpts devpts bookworm/dev/pts mount --bind /dev bookworm/dev mount --bind /sys bookworm/sys chroot bookworm/ /bin/bash --login apt install locales dpkg-reconfigure locales LANG=en_US.UTF-8 echo "LANG=en_US.UTF-8" >> /etc/profile apt install sane-utils
Using scanimage in the chroot environment by unprivileged users
For this purpose I wrote a small program named chroot_scanimage.
