I tried to upgrade my older laptop (which is taking dust) from Trisquel 7 to
Trisquel 8. I first disabled the external repositories (e.g., jxself's since
I use the latest Linux-libre). After discovering that neither
'update-manager -d' nor 'sudo do-release-upgrade -d' would propose me to
update, I changed all "belenos" in /etc/apt/sources.list to "flidas" ('sudo
sed -i s/belenos/flidas/' /etc/apt/sources.list) and:
I ran 'sudo apt upgrade'. At that point I thought everything went well and
just copied the errors/warnings into "1. original-apt-upgrade.txt". However,
I was about to discover that the last logged error is malignant:
Errors were encountered while processing:
libclutter-imcontext-0.1-bin
ibus-clutter:amd64
sa-compile
E: Sub-process /usr/bin/dpkg returned an error code (1)
A reboot later, GDM did not start. I logged into tty1 and tried again 'sudo
apt upgrade'. In vain. The log, "2. failed-apt-upgrade-after-reboot.txt",
ends with:
/usr/bin/clutter-scan-immodules: relocation error:

libclutter-imcontext-0.1-bin

E: Sub-process /usr/bin/dpkg returned an error code (1)
Since before that, there was a long list of packages to "autoremove", I did
'sudo apt-get autoremove' and, again, 'sudo apt upgrade', which upgraded 43
packages and installed 131 packages. However, the log, "3.
apt-upgrade-after-autoremove.txt", ended like before:
Errors were encountered while processing:
libclutter-imcontext-0.1-bin
ibus-clutter:amd64
sa-compile
E: Sub-process /usr/bin/dpkg returned an error code (1)
I therefore decided to 'sudo apt remove sa-compile', what went well,
according to "4. apt-remove-sa-compile.txt".
I proceeded to 'sudo apt remove libclutter-imcontext-0.1-bin', that went well
too, according to "5. apt-remove-libclutter-imcontext-0.1-bin.txt" (and
"ibus-clutter" depending on "libclutter-imcontext-0.1-bin", it was removed as
well).
After all that, I still could not get a graphical session, probably because
'sudo apt-get autoremove' removed too much. I therefore decided to install
the default desktop with 'sudo apt install trisquel', which apparently went
well (I did not save the logs). On the contrary, 'sudo apt install
trisquel-recommended' does not work, for depending on packages that are still
absent (if I remember well the error).
I executed 'sudo start lightdm' and could log into the MATE desktop... but
the icons on the desktop did not load, the cursor spun forever and the system
was lagging a lot. I managed after some time to get back to tty1 and 'top'
showed me that 'mate-settings-daemon' (if I remember well) and X were
occupying the CPU.
Worse, any attempt to use 'apt' or 'apt-get' (even to just show its version
with "-v") now gives this error:
apt: relocation error: /usr/lib/x86_64-linux-gnu/libapt-pkg.so.5.0: symbol
_ZNKSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE7compareERKS4_, version
GLIBCXX_3.4.21 not defined in file libstdc++.so.6 with link time reference
I hope that helps to fix issues in the upgrade process. It does not look
ready. At least not for my selection of packages. I did not think of saving
that selection (which notably includes GNOME Shell) before the upgrade.
However, my current laptop has a similar selection. Indeed, I used
https://trisquel.info/en/wiki/cloning-system-or-how-make-copy-installed-packages-one-computer-another
to initially set it up a few months ago. I can give its list of installed
packages, if useful.
I will try to install from ISO on the older laptop.
