DPKG install fails with read only filesystem on non read-only filesystem
Hello,
for various reasons I am currently writing a script to install packages
by calling dpkg -i package.deb.
This mechanism has worked fine for a while. Now I need to call said
script using sudo noninteractively from a webserver.
This leads me to my error:
Mar 26 11:36:42 debbuilder package-updater[32246]: (Reading database ...
124404 files and directories currently installed.)
Mar 26 11:36:42 debbuilder package-updater[32246]: Preparing to unpack

(--install):

mess surrounding `./usr/share/doc/package' before installing another
version: Read-only file system
Mar 26 11:36:42 debbuilder package-updater[32246]: Errors were
encountered while processing:
Mar 26 11:36:42 debbuilder package-updater[32246]:
/tmp/package-update-unpack/unpack/package_0.2_all.deb
Neither /tmp nor /usr is non writeable.
Calling the package install script manually via sudo from a normal user
runs everything as normal without any error. So the package itself is
not a problem ( apparently ).
I've been trying to find the source of this error since a couple of
hours now. I haven't been able to make any real progress and was
wondering whether anyone here would have an idea whats going wrong.
This error is happening on two independent debian systems.
/ is mounted
/dev/sda1 on / type ext4 (rw,relatime,data=ordered)
tmp is a normal folder not another mountpoint
The packages are uploaded via a python webserver. However the package
integrity is checked before applying the install. The packages
themselves are intact.
Best regards,
Felix
