I have a minimal Ubuntu Server 16.04 installation on an old x86_64 desktop PC. Tried installing graphic UI with tasksel (selected Lubuntu desktop and OpenSSH Server), but near 90% of process at Configuring memtest86+ I got the following error:
EXT4-fs (sda3): write access unavailable, cannot proceed
EXT4-fs (sda1): write access unavailable, cannot proceed
and now tasksel is stalled.
The whole sda disk is not actually mounted, root and home directories are mounted from sdb1 and sdb3. The system boots from the sdb disk (it's selected in BIOS). Swap uses sdb2 partition. So I'm not sure why sda got involved.
How can I fix it or interrupt the process without breaking things?
Via another console I mounted sda1 and sda3, but of course tasksel is still frozen.
Also, tasksel was started by root user, ps -ef shows it as root's process.
/etc/fstab. Do a recovery-mode boot, so you mustmount -o remount, rw /and see where is sda in fstab file. – Redbob Sep 26 '17 at 14:07taskselprocess, ransudo dpkg --configure -awithsdapartitions mounted, it seems nothing broke.. – xealits Sep 26 '17 at 17:07
