I updated my Ubuntu 20.04.4 to be able to upgrade it to 22.04.1, but I am experiencing problems with
libdeflate0. As already mentioned in the title, there is a dependency conflict:
sudo apt list --upgradable -a Listing... Done libdeflate0/focal 1.12-1~20.04.sav0 amd64 [upgradable from: 1.8-1ubuntu1~20.04.sav0] libdeflate0/now 1.8-1ubuntu1~20.04.sav0 amd64 [installed,upgradable to: 1.12-1~20.04.sav0] libdeflate0/focal 1.5-3 amd64
none of the above is a suitable option, because of unmet dependencies. Thus, I tried:
sudo aptitude remove libdeflate0 The following packages will be REMOVED: libdeflate0 0 packages upgraded, 0 newly installed, 1 to remove and 0 not upgraded. Need to get 0 B of archives. After unpacking 129 kB will be freed. The following packages have unmet dependencies: libtiff5 : Depends: libdeflate0 (>= 1.0) but it is not going to be installed The following actions will resolve these dependencies: Keep the following packages at their current version: 1) libdeflate0 [1.8-1ubuntu1~20.04.sav0 (now)] Accept this solution? [Y/n/q/?]
with no suitable results. Typing
n, the other options (more than 15) suggested removing many programs (e.g., wine and wine32), because of the spread of this packages across the dependencies. Then I tried:
sudo dpkg -l --force-remove-reinstreq libdeflate0 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-=================-=======================-============-============================================================== ri libdeflate0:amd64 1.8-1ubuntu1~20.04.sav0 amd64 fast, whole-buffer DEFLATE-based compression and decompression ii libdeflate0:i386 1.8-1ubuntu1~20.04.sav0 i386 fast, whole-buffer DEFLATE-based compression and decompression
without success. Do you have any suggestion on how to proceed?
n to the question. If this removes a lot of packages, then have these removed. Then fully update the system with a
sudo apt dist-upgrade and proceed with the upgrade to Ubuntu 22.04. Once booted into Ubuntu 22.04, reinstall the packages. All user configuration will have been preserved.
