Installing FS Archiver takes a couple of steps beyond what is described on their website.

Get it from from https://www.fsarchiver.org/installation/;

  • wget https://github.com/fdupoux/fsarchiver/releases/download/0.8.6/fsarchiver-0.8.6-1.el7.x86_64.rpm

Install it (spoiler alert, it won't work);

  • yum install fsarchiver-0.8.6-1.el7.x86_64.rpm

Error:

Problem: conflicting requests

  - nothing provides libgcrypt.so.11()(64bit) needed by fsarchiver-0.8.6-1.el7.x86_64

  - nothing provides libgcrypt.so.11(GCRYPT_1.2)(64bit) needed by fsarchiver-0.8.6-1.el7.x86_64

OK, get that package (it isn't available with Rocky / CentOS 8 or 9, but it is with Cent OS 7)

  • wget https://rpmfind.net/linux/centos/7.9.2009/os/x86_64/Packages/libgcrypt-1.5.3-14.el7.x86_64.rpm

Install it (spoiler alert, it won't work);

yum install libgcrypt-1.5.3-14.el7.x86_64.rpm

Error:

Problem: problem with installed package systemd-libs-239-68.el8_7.2.x86_64

  - package systemd-libs-239-68.el8_7.2.x86_64 requires libgcrypt.so.20()(64bit), but none of the providers can be installed

  - package systemd-libs-239-68.el8_7.2.x86_64 requires libgcrypt.so.20(GCRYPT_1.6)(64bit), but none of the providers can be installed

  - package systemd-libs-239-68.el8.x86_64 requires libgcrypt.so.20()(64bit), but none of the providers can be installed

  - package systemd-libs-239-68.el8.x86_64 requires libgcrypt.so.20(GCRYPT_1.6)(64bit), but none of the providers can be installed

  - cannot install both libgcrypt-1.5.3-14.el7.x86_64 and libgcrypt-1.8.5-7.el8_6.x86_64

  - conflicting requests

This "conflict" makes no sense in terms of files.

Let's take a look at what's inside the libgcrypt-1.5.3-14.el7.x86_64.rpm file;

Extract it: rpm2cpio libgcrypt-1.5.3-14.el7.x86_64.rpm | cpio -idmv (from https://www.cyberciti.biz/tips/how-to-extract-an-rpm-package-without-installing-it.html)

Contents of libgcrypt-1.5.3-14.el7.x86_64.rpm;

./etc/gcrypt
./usr/lib64/.libgcrypt.so.11.hmac
./usr/lib64/libgcrypt.so.11
./usr/lib64/libgcrypt.so.11.8.2
./usr/share/doc/libgcrypt-1.5.3
./usr/share/doc/libgcrypt-1.5.3/AUTHORS
./usr/share/doc/libgcrypt-1.5.3/COPYING.LIB
./usr/share/doc/libgcrypt-1.5.3/NEWS
./usr/share/doc/libgcrypt-1.5.3/THANKS

OK, what's inside the /usr/lib64 Directory on Rocky Linux;

libgcrypt.so -> libgcrypt.so.20
libgcrypt.so.20 -> libgcrypt.so.20.2.5
libgcrypt.so.20.2.5
.libgcrypt.so.20.hmac

...hmmm, no conflicts are going to arise there. Let's check CentOS 7;

libgcrypt.so.11 -> libgcrypt.so.11.8.2
libgcrypt.so.11.8.2
.libgcrypt.so.11.hmac

...confirmed. Ain't gonna be no conflict there!

Cool, let's install libgcrypt-1.5.3-14.el7.x86_64.rpm (spoiler alert, it wont work either);

  • yum install libgcrypt-1.5.3-14.el7.x86_64.rpm

Error:

Problem: problem with installed package systemd-libs-239-68.el8_7.2.x86_64

  - package systemd-libs-239-68.el8_7.2.x86_64 requires libgcrypt.so.20()(64bit), but none of the providers can be installed

  - package systemd-libs-239-68.el8_7.2.x86_64 requires libgcrypt.so.20(GCRYPT_1.6)(64bit), but none of the providers can be installed

  - package systemd-libs-239-68.el8.x86_64 requires libgcrypt.so.20()(64bit), but none of the providers can be installed

  - package systemd-libs-239-68.el8.x86_64 requires libgcrypt.so.20(GCRYPT_1.6)(64bit), but none of the providers can be installed

  - cannot install both libgcrypt-1.5.3-14.el7.x86_64 and libgcrypt-1.8.5-7.el8_6.x86_64

  - conflicting requests

Forget it. Do it manually;

  • Copy the libgcrypt.so.11.8.s and .libgcrypt.so.11.hmac to /usr/lib64 from the extracted RPM file (see above)
  • Create a symbolic link: ln -s libgcrypt.so.11.8.2 libgcrypt.so.11

OK, back to installing FSArchiver (spoiler alert yet again, nothing happens / nothing is accomplished);

  • yum install fsarchiver-0.8.6-1.el7.x86_64.rpm

Dependencies resolved.

Nothing to do.

Complete!

Forget this crap. And to forget it we'll need to jump slightly outside of the YUM / DNF paradigm;

  • rpm -Uhv /usr/src/fsarchiver-0.8.6-1.el7.x86_64.rpm --nodeps

Done! Installed! Finished! Working;
